It helps to instantiate, initialize and coordinate the many - objects that make up your app. - - Each Ember app has one and only one `Ember.Application` object. In fact, the - very first thing you should do in your application is create the instance: - - ```javascript - window.App = Ember.Application.create(); - ``` - - Typically, the application object is the only global variable. All other - classes in your app should be properties on the `Ember.Application` instance, - which highlights its first role: a global namespace. - - For example, if you define a view class, it might look like this: - - ```javascript - App.MyView = Ember.View.extend(); - ``` - - By default, calling `Ember.Application.create()` will automatically initialize - your application by calling the `Ember.Application.initialize()` method. If - you need to delay initialization, you can call your app's `deferReadiness()` - method. When you are ready for your app to be initialized, call its - `advanceReadiness()` method. - - You can define a `ready` method on the `Ember.Application` instance, which - will be run by Ember when the application is initialized. - - Because `Ember.Application` inherits from `Ember.Namespace`, any classes - you create will have useful string representations when calling `toString()`. - See the `Ember.Namespace` documentation for more information. - - While you can think of your `Ember.Application` as a container that holds the - other classes in your application, there are several other responsibilities - going on under-the-hood that you may want to understand. - - ### Event Delegation - - Ember uses a technique called _event delegation_. This allows the framework - to set up a global, shared event listener instead of requiring each view to - do it manually. For example, instead of each view registering its own - `mousedown` listener on its associated element, Ember sets up a `mousedown` - listener on the `body`. - - If a `mousedown` event occurs, Ember will look at the target of the event and - start walking up the DOM node tree, finding corresponding views and invoking - their `mouseDown` method as it goes. - - `Ember.Application` has a number of default events that it listens for, as - well as a mapping from lowercase events to camel-cased view method names. For - example, the `keypress` event causes the `keyPress` method on the view to be - called, the `dblclick` event causes `doubleClick` to be called, and so on. - - If there is a bubbling browser event that Ember does not listen for by - default, you can specify custom events and their corresponding view method - names by setting the application's `customEvents` property: - - ```javascript - var App = Ember.Application.create({ - customEvents: { - // add support for the paste event - paste: 'paste' - } - }); - ``` - - By default, the application sets up these event listeners on the document - body. However, in cases where you are embedding an Ember application inside - an existing page, you may want it to set up the listeners on an element - inside the body. - - For example, if only events inside a DOM element with the ID of `ember-app` - should be delegated, set your application's `rootElement` property: - - ```javascript - var App = Ember.Application.create({ - rootElement: '#ember-app' - }); - ``` - - The `rootElement` can be either a DOM element or a jQuery-compatible selector - string. Note that *views appended to the DOM outside the root element will - not receive events.* If you specify a custom root element, make sure you only - append views inside it! - - To learn more about the advantages of event delegation and the Ember view - layer, and a list of the event listeners that are setup by default, visit the - [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation). - - ### Initializers - - Libraries on top of Ember can add initializers, like so: - - ```javascript - Ember.Application.initializer({ - name: 'api-adapter', - - initialize: function(container, application) { - application.register('api-adapter:main', ApiAdapter); - } - }); - ``` - - Initializers provide an opportunity to access the container, which - organizes the different components of an Ember application. Additionally - they provide a chance to access the instantiated application. Beyond - being used for libraries, initializers are also a great way to organize - dependency injection or setup in your own application. - - ### Routing - - In addition to creating your application's router, `Ember.Application` is - also responsible for telling the router when to start routing. Transitions - between routes can be logged with the `LOG_TRANSITIONS` flag, and more - detailed intra-transition logging can be logged with - the `LOG_TRANSITIONS_INTERNAL` flag: - - ```javascript - var App = Ember.Application.create({ - LOG_TRANSITIONS: true, // basic logging of successful transitions - LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps - }); - ``` - - By default, the router will begin trying to translate the current URL into - application state once the browser emits the `DOMContentReady` event. If you - need to defer routing, you can call the application's `deferReadiness()` - method. Once routing can begin, call the `advanceReadiness()` method. - - If there is any setup required before routing begins, you can implement a - `ready()` method on your app that will be invoked immediately before routing - begins. - ``` - - @class Application - @namespace Ember - @extends Ember.Namespace - */ - - var Application = Namespace.extend(DeferredMixin, { - _suppressDeferredDeprecation: true, - - /** - The root DOM element of the Application.

The underlying data object of the selected `<option>` is - stored in the `Element.Select`'s `value` property. - - ## The Content Property (array of strings) - - The simplest version of an `Ember.Select` takes an array of strings as its - `content` property.

The `optionLabelPath` - specifies the path on each object to the desired property for the - element's text. Both paths must reference each object itself as `content`: - - ```javascript - App.ApplicationController = Ember.ObjectController.extend({ - programmers: [ - {firstName: "Yehuda", id: 1}, - {firstName: "Tom", id: 2} - ] - }); - ``` - - ```handlebars - {{view "select" - content=programmers - optionValuePath="content.id" - optionLabelPath="content.firstName"}} - ``` - - Would result in the following HTML: - - ```html - <select class="ember-select"> - <option value="1">Yehuda</option> - <option value="2">Tom</option> - </select> - ``` - - The `value` attribute of the selected `<option>` within an `Ember.Select` - can be bound to a property on another object: - - ```javascript - App.ApplicationController = Ember.ObjectController.extend({ - programmers: [ - {firstName: "Yehuda", id: 1}, - {firstName: "Tom", id: 2} - ], - currentProgrammer: { - id: 2 - } - }); - ``` - - ```handlebars - {{view "select" - content=programmers - optionValuePath="content.id" - optionLabelPath="content.firstName" - value=currentProgrammer.id}} - ``` - - Would result in the following HTML with a selected option: - - ```html - <select class="ember-select"> - <option value="1">Yehuda</option> - <option value="2" selected="selected">Tom</option> - </select> - ``` - - Interacting with the rendered element by selecting the first option - ('Yehuda') will update the `id` of `currentProgrammer` - to match the `value` property of the newly selected `<option>`. - - Alternatively, you can control selection through the underlying objects - used to render each object by binding the `selection` option. When the selected - `<option>` is changed, the property path provided to `selection` - will be updated to match the content object of the rendered `<option>` - element: - - ```javascript - - var yehuda = {firstName: "Yehuda", id: 1, bff4eva: 'tom'} - var tom = {firstName: "Tom", id: 2, bff4eva: 'yehuda'}; - - App.ApplicationController = Ember.ObjectController.extend({ - selectedPerson: tom, - programmers: [ yehuda, tom ] - }); - ``` - - ```handlebars - {{view "select" - content=programmers - optionValuePath="content.id" - optionLabelPath="content.firstName" - selection=selectedPerson}} - ``` - - Would result in the following HTML with a selected option: - - ```html - <select class="ember-select"> - <option value="1">Yehuda</option> - <option value="2" selected="selected">Tom</option> - </select> - ``` - - Interacting with the rendered element by selecting the first option - ('Yehuda') will update the `selectedPerson` to match the object of - the newly selected `<option>`. In this case it is the first object - in the `programmers` - - ## Supplying a Prompt - - A `null` value for the `Ember.Select`'s `value` or `selection` property - results in there being no `<option>` with a `selected` attribute: - - ```javascript - App.ApplicationController = Ember.ObjectController.extend({ - selectedProgrammer: null, - programmers: ["Yehuda", "Tom"] - }); - ``` - - ``` handlebars - {{view "select" - content=programmers - value=selectedProgrammer - }} - ``` - - Would result in the following HTML: - - ```html - <select class="ember-select"> - <option value="Yehuda">Yehuda</option> - <option value="Tom">Tom</option> - </select> - ``` - - Although `selectedProgrammer` is `null` and no `<option>` - has a `selected` attribute the rendered HTML will display the - first item as though it were selected. You can supply a string - value for the `Ember.Select` to display when there is no selection - with the `prompt` option: - - ```javascript - App.ApplicationController = Ember.ObjectController.extend({ - selectedProgrammer: null, - programmers: [ "Yehuda", "Tom" ] - }); - ``` - - ```handlebars - {{view "select" - content=programmers - value=selectedProgrammer - prompt="Please select a name" - }} - ``` - - Would result in the following HTML: - - ```html - <select class="ember-select"> - <option>Please select a name</option> - <option value="Yehuda">Yehuda</option> - <option value="Tom">Tom</option> - </select> - ``` - - @class Select - @namespace Ember - @extends Ember.View - */ - var Select = View.extend({ - instrumentDisplay: 'Ember.Select', - - tagName: 'select', - classNames: ['ember-select'], - defaultTemplate: Ember.Handlebars.template({"1":function(depth0,helpers,partials,data) { - var stack1, buffer = ''; - data.buffer.push("<option value=\"\">"); - stack1 = helpers._triageMustache.call(depth0, "view.prompt", {"name":"_triageMustache","hash":{},"hashTypes":{},"hashContexts":{},"types":["ID"],"contexts":[depth0],"data":data}); - if (stack1 != null) { data.buffer.push(stack1); } - data.buffer.push("</option>"); - return buffer; - },"3":function(depth0,helpers,partials,data) { - var stack1; - stack1 = helpers.each.call(depth0, "group", "in", "view.groupedContent", {"name":"each","hash":{},"hashTypes":{},"hashContexts":{},"fn":this.program(4, data),"inverse":this.noop,"types":["ID","ID","ID"],"contexts":[depth0,depth0,depth0],"data":data}); - if (stack1 != null) { data.buffer.push(stack1); } - else { data.buffer.push(''); } - },"4":function(depth0,helpers,partials,data) { - var escapeExpression=this.escapeExpression; - data.buffer.push(escapeExpression(helpers.view.call(depth0, "view.groupView", {"name":"view","hash":{ - 'label': ("group.label"), - 'content': ("group.content") - },"hashTypes":{'label': "ID",'content': "ID"},"hashContexts":{'label': depth0,'content': depth0},"types":["ID"],"contexts":[depth0],"data":data}))); - },"6":function(depth0,helpers,partials,data) { - var stack1; - stack1 = helpers.each.call(depth0, "item", "in", "view.content", {"name":"each","hash":{},"hashTypes":{},"hashContexts":{},"fn":this.program(7, data),"inverse":this.noop,"types":["ID","ID","ID"],"contexts":[depth0,depth0,depth0],"data":data}); - if (stack1 != null) { data.buffer.push(stack1); } - else { data.buffer.push(''); } - },"7":function(depth0,helpers,partials,data) { - var escapeExpression=this.escapeExpression; - data.buffer.push(escapeExpression(helpers.view.call(depth0, "view.optionView", {"name":"view","hash":{ - 'content': ("item") - },"hashTypes":{'content': "ID"},"hashContexts":{'content': depth0},"types":["ID"],"contexts":[depth0],"data":data}))); - },"compiler":[6,">= 2.0.0-beta.1"],"main":function(depth0,helpers,partials,data) { - var stack1, buffer = ''; - stack1 = helpers['if'].call(depth0, "view.prompt", {"name":"if","hash":{},"hashTypes":{},"hashContexts":{},"fn":this.program(1, data),"inverse":this.noop,"types":["ID"],"contexts":[depth0],"data":data}); - if (stack1 != null) { data.buffer.push(stack1); } - stack1 = helpers['if'].call(depth0, "view.optionGroupPath", {"name":"if","hash":{},"hashTypes":{},"hashContexts":{},"fn":this.program(3, data),"inverse":this.program(6, data),"types":["ID"],"contexts":[depth0],"data":data}); - if (stack1 != null) { data.buffer.push(stack1); } - return buffer; - },"useData":true}), - attributeBindings: ['multiple', 'disabled', 'tabindex', 'name', 'required', 'autofocus', - 'form', 'size'], - - /** - The `multiple` attribute of the select element.

Example: - - ```handlebars - {{repeat text count=numRepeats}} - ``` - - In this example, count will be bound to the value of - the `numRepeats` property on the context. If that property - changes, the helper will be re-rendered. - - ## Example with extra dependencies - - The `Ember.Handlebars.registerBoundHelper` method takes a variable length - third parameter which indicates extra dependencies on the passed in value. - This allows the handlebars helper to update when these dependencies change. - - ```javascript - Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) { - return value.get('name').toUpperCase(); - }, 'name'); - ``` - - ## Example with multiple bound properties - - `Ember.Handlebars.registerBoundHelper` supports binding to - multiple properties, e.g.: - - ```javascript - Ember.Handlebars.registerBoundHelper('concatenate', function() { - var values = Array.prototype.slice.call(arguments, 0, -1); - return values.join('||'); - }); - ``` - - Which allows for template syntax such as `{{concatenate prop1 prop2}}` or - `{{concatenate prop1 prop2 prop3}}`.

Each string can be: - - * a string return value of an object's property. - * a boolean return value of an object's property - * a hard-coded value - - A string return value works identically to other uses of `bind-attr`. The - return value of the property will become the value of the attribute. For - example, the following view and template: - - ```javascript - AView = View.extend({ - someProperty: function() { - return "aValue"; - }.property() - }) - ``` - - ```handlebars - <img {{bind-attr class="view.someProperty}}> - ``` - - Result in the following rendered output: - - ```html - <img class="aValue"> - ``` - - A boolean return value will insert a specified class name if the property - returns `true` and remove the class name if the property returns `false`. - - A class name is provided via the syntax - `somePropertyName:class-name-if-true`. - - ```javascript - AView = View.extend({ - someBool: true - }) - ``` - - ```handlebars - <img {{bind-attr class="view.someBool:class-name-if-true"}}> - ``` - - Result in the following rendered output: - - ```html - <img class="class-name-if-true"> - ``` - - An additional section of the binding can be provided if you want to - replace the existing class instead of removing it when the boolean - value changes: - - ```handlebars - <img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}> - ``` - - A hard-coded value can be used by prepending `:` to the desired - class name: `:class-name-to-always-apply`. - - ```handlebars - <img {{bind-attr class=":class-name-to-always-apply"}}> - ``` - - Results in the following rendered output: - - ```html - <img class="class-name-to-always-apply"> - ``` - - All three strategies - string return value, boolean return value, and - hard-coded value – can be combined in a single declaration: - - ```handlebars - <img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}> - ``` - - @method bind-attr - @for Ember.Handlebars.helpers - @param {Hash} options - @return {String} HTML string - */ - function bindAttrHelper(options) { - var attrs = options.hash; - - Ember.assert("You must specify at least one hash argument to bind-attr", !!keys(attrs).length); - - var view = options.data.view; - var ret = []; - - // we relied on the behavior of calling without - // context to mean this === window, but when running - // "use strict", it's possible for this to === undefined; - var ctx = this || window; - - // Generate a unique id for this element.

The contents of this block will render - if the collection is empty. - - ``` - {{#each person in developers}} - {{person.name}} - {{else}} - <p>Sorry, nobody is available for this task.</p> - {{/each}} - ``` - - ### Specifying an alternative view for each item - - `itemViewClass` can control which view will be used during the render of each - item's template. - - The following template: - - ```handlebars - <ul> - {{#each developer in developers itemViewClass="person"}} - {{developer.name}} - {{/each}} - </ul> - ``` - - Will use the following view for each item - - ```javascript - App.PersonView = Ember.View.extend({ - tagName: 'li' - }); - ``` - - Resulting in HTML output that looks like the following: - - ```html - <ul> - <li class="ember-view">Yehuda</li> - <li class="ember-view">Tom</li> - <li class="ember-view">Paul</li> - </ul> - ``` - - `itemViewClass` also enables a non-block form of `{{each}}`. The view - must {{#crossLink "Ember.View/toc_templates"}}provide its own template{{/crossLink}}, - and then the block should be dropped. An example that outputs the same HTML - as the previous one: - - ```javascript - App.PersonView = Ember.View.extend({ - tagName: 'li', - template: '{{developer.name}}' - }); - ``` - - ```handlebars - <ul> - {{each developer in developers itemViewClass="person"}} - </ul> - ``` - - ### Specifying an alternative view for no items (else) - - The `emptyViewClass` option provides the same flexibility to the `{{else}}` - case of the each helper. - - ```javascript - App.NoPeopleView = Ember.View.extend({ - tagName: 'li', - template: 'No person is available, sorry' - }); - ``` - - ```handlebars - <ul> - {{#each developer in developers emptyViewClass="no-people"}} - <li>{{developer.name}}</li> - {{/each}} - </ul> - ``` - - ### Wrapping each item in a controller - - Controllers in Ember manage state and decorate data. In many cases, - providing a controller for each item in a list can be useful. - Specifically, an {{#crossLink "Ember.ObjectController"}}Ember.ObjectController{{/crossLink}} - should probably be used. Item controllers are passed the item they - will present as a `model` property, and an object controller will - proxy property lookups to `model` for us. - - This allows state and decoration to be added to the controller - while any other property lookups are delegated to the model. An example: - - ```javascript - App.RecruitController = Ember.ObjectController.extend({ - isAvailableForHire: function() { - return !this.get('isEmployed') && this.get('isSeekingWork'); - }.property('isEmployed', 'isSeekingWork') - }) - ``` - - ```handlebars - {{#each person in developers itemController="recruit"}} - {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} - {{/each}} - ``` - - @method each - @for Ember.Handlebars.helpers - @param [name] {String} name for item (used with `in`) - @param [path] {String} path - @param [options] {Object} Handlebars key/value pairs of options - @param [options.itemViewClass] {String} a path to a view class used for each item - @param [options.emptyViewClass] {String} a path to a view class used for each item - @param [options.itemController] {String} name of a controller to be created for each item - */ - function eachHelper(path) { - var options = arguments[arguments.length - 1]; - var helperName = 'each'; - var keywordName; - - if (arguments.length === 4) { - Ember.assert("If you pass more than one argument to the each helper," + - " it must be in the form #each foo in bar", arguments[1] === "in"); - - keywordName = arguments[0]; - path = arguments[2]; - - helperName += ' ' + keywordName + ' in ' + path; - - options.hash.keyword = keywordName; - } else if (arguments.length === 1) { - path = ''; - } else { - helperName += ' ' + path; - } - - Ember.deprecate('Using the context switching form of {{each}} is deprecated.

The value of this property should be a string representing a path - to another object or a custom binding instance created using Binding helpers - (see "One Way Bindings"): - - ``` - valueBinding: "MyApp.someController.title" - ``` - - This will create a binding from `MyApp.someController.title` to the `value` - property of your object instance automatically. Now the two values will be - kept in sync. - - ## One Way Bindings - - One especially useful binding customization you can use is the `oneWay()` - helper. This helper tells Ember that you are only interested in - receiving changes on the object you are binding from. For example, if you - are binding to a preference and you want to be notified if the preference - has changed, but your object will not be changing the preference itself, you - could do: - - ``` - bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") - ``` - - This way if the value of `MyApp.preferencesController.bigTitles` changes the - `bigTitles` property of your object will change also. However, if you - change the value of your `bigTitles` property, it will not update the - `preferencesController`. - - One way bindings are almost twice as fast to setup and twice as fast to - execute because the binding only has to worry about changes to one side. - - You should consider using one way bindings anytime you have an object that - may be created frequently and you do not intend to change a property; only - to monitor it for changes (such as in the example above). - - ## Adding Bindings Manually - - All of the examples above show you how to configure a custom binding, but the - result of these customizations will be a binding template, not a fully active - Binding instance. The binding will actually become active only when you - instantiate the object the binding belongs to. It is useful however, to - understand what actually happens when the binding is activated. - - For a binding to function it must have at least a `from` property and a `to` - property. The `from` property path points to the object/key that you want to - bind from while the `to` path points to the object/key you want to bind to. - - When you define a custom binding, you are usually describing the property - you want to bind from (such as `MyApp.someController.value` in the examples - above). When your object is created, it will automatically assign the value - you want to bind `to` based on the name of your binding key. In the - examples above, during init, Ember objects will effectively call - something like this on your binding: - - ```javascript - binding = Ember.Binding.from("valueBinding").to("value"); - ``` - - This creates a new binding instance based on the template you provide, and - sets the to path to the `value` property of the new object. Now that the - binding is fully configured with a `from` and a `to`, it simply needs to be - connected to become active. This is done through the `connect()` method: - - ```javascript - binding.connect(this); - ``` - - Note that when you connect a binding you pass the object you want it to be - connected to. This object will be used as the root for both the from and - to side of the binding when inspecting relative paths. This allows the - binding to be automatically inherited by subclassed objects as well. - - This also allows you to bind between objects using the paths you declare in - `from` and `to`: - - ```javascript - // Example 1 - binding = Ember.Binding.from("App.someObject.value").to("value"); - binding.connect(this); - - // Example 2 - binding = Ember.Binding.from("parentView.value").to("App.someObject.value"); - binding.connect(this); - ``` - - Now that the binding is connected, it will observe both the from and to side - and relay changes. - - If you ever needed to do so (you almost never will, but it is useful to - understand this anyway), you could manually create an active binding by - using the `Ember.bind()` helper method. (This is the same method used by - to setup your bindings on objects): - - ```javascript - Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); - ``` - - Both of these code fragments have the same effect as doing the most friendly - form of binding creation like so: - - ```javascript - MyApp.anotherObject = Ember.Object.create({ - valueBinding: "MyApp.someController.value", - - // OTHER CODE FOR THIS OBJECT... - }); - ``` - - Ember's built in binding creation method makes it easy to automatically - create bindings for you. You should always use the highest-level APIs - available, even if you understand how it works underneath. - - @class Binding - @namespace Ember - @since Ember 0.9 - */ - // Ember.Binding = Binding; ES6TODO: where to put this? - - - /** - Global helper method to create a new binding.

In this case, no additional parameters will be passed. - - If you provide additional parameters to the helper: - - ```handlebars - <button {{action 'edit' post}}>Edit</button> - ``` - - Those parameters will be passed along as arguments to the JavaScript - function implementing the action. - - ### Event Propagation - - Events triggered through the action helper will automatically have - `.preventDefault()` called on them. You do not need to do so in your event - handlers. If you need to allow event propagation (to handle file inputs for - example) you can supply the `preventDefault=false` option to the `{{action}}` helper: - - ```handlebars - <div {{action "sayHello" preventDefault=false}}> - <input type="file" /> - <input type="checkbox" /> - </div> - ``` - - To disable bubbling, pass `bubbles=false` to the helper: - - ```handlebars - <button {{action 'edit' post bubbles=false}}>Edit</button> - ``` - - If you need the default handler to trigger you should either register your - own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html) - 'Responding to Browser Events' for more information. - - ### Specifying DOM event type - - By default the `{{action}}` helper registers for DOM `click` events. You can - supply an `on` option to the helper to specify a different DOM event name: - - ```handlebars - <div {{action "anActionName" on="doubleClick"}}> - click me - </div> - ``` - - See `Ember.View` 'Responding to Browser Events' for a list of - acceptable DOM event names. - - ### Specifying whitelisted modifier keys - - By default the `{{action}}` helper will ignore click event with pressed modifier - keys. You can supply an `allowedKeys` option to specify which keys should not be ignored. - - ```handlebars - <div {{action "anActionName" allowedKeys="alt"}}> - click me - </div> - ``` - - This way the `{{action}}` will fire when clicking with the alt key pressed down. - - Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys. - - ```handlebars - <div {{action "anActionName" allowedKeys="any"}}> - click me with any key pressed - </div> - ``` - - ### Specifying a Target - - There are several possible target objects for `{{action}}` helpers: - - In a typical Ember application, where templates are managed through use of the - `{{outlet}}` helper, actions will bubble to the current controller, then - to the current route, and then up the route hierarchy. - - Alternatively, a `target` option can be provided to the helper to change - which object will receive the method call. This option must be a path - to an object, accessible in the current context: - - ```handlebars - {{! the application template }} - <div {{action "anActionName" target=view}}> - click me - </div> - ``` - - ```javascript - App.ApplicationView = Ember.View.extend({ - actions: { - anActionName: function(){} - } - }); - - ``` - - ### Additional Parameters - - You may specify additional parameters to the `{{action}}` helper. These - parameters are passed along as the arguments to the JavaScript function - implementing the action. - - ```handlebars - {{#each person in people}} - <div {{action "edit" person}}> - click me - </div> - {{/each}} - ``` - - Clicking "click me" will trigger the `edit` method on the current controller - with the value of `person` as a parameter. - - @method action - @for Ember.Handlebars.helpers - @param {String} actionName - @param {Object} [context]* - @param {Hash} options - */ - function actionHelper(actionName) { - var length = arguments.length;

This argument will become - the model context of the linked route: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); - }); - ``` - - ```handlebars - {{#link-to 'photoGallery' aPhoto}} - {{aPhoto.title}} - {{/link-to}} - ``` - - ```html - <a href="/hamster-photos/42"> - Tomster - </a> - ``` - - ### Supplying multiple models - For deep-linking to route paths that contain multiple - dynamic segments, multiple model arguments can be used. - As the router transitions through the route path, each - supplied model argument will become the context for the - route with the dynamic segments: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() { - this.route("comment", {path: "comments/:comment_id"}); - }); - }); - ``` - This argument will become the model context of the linked route: - - ```handlebars - {{#link-to 'photoGallery.comment' aPhoto comment}} - {{comment.body}} - {{/link-to}} - ``` - - ```html - <a href="/hamster-photos/42/comment/718"> - A+++ would snuggle again. - </a> - ``` - - ### Supplying an explicit dynamic segment value - If you don't have a model object available to pass to `{{link-to}}`, - an optional string or integer argument can be passed for routes whose - paths contain dynamic segments. This argument will become the value - of the dynamic segment: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); - }); - ``` - - ```handlebars - {{#link-to 'photoGallery' aPhotoId}} - {{aPhoto.title}} - {{/link-to}} - ``` - - ```html - <a href="/hamster-photos/42"> - Tomster - </a> - ``` - - When transitioning into the linked route, the `model` hook will - be triggered with parameters including this passed identifier. - - ### Allowing Default Action - - By default the `{{link-to}}` helper prevents the default browser action - by calling `preventDefault()` as this sort of action bubbling is normally - handled internally and we do not want to take the browser to a new URL (for - example). - - If you need to override this behavior specify `preventDefault=false` in - your template: - - ```handlebars - {{#link-to 'photoGallery' aPhotoId preventDefault=false}} - {{aPhotoId.title}} - {{/link-to}} - ``` - - ### Overriding attributes - You can override any given property of the Ember.LinkView - that is generated by the `{{link-to}}` helper by passing - key/value pairs, like so: - - ```handlebars - {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}} - Uh-mazing! - {{/link-to}} - ``` - - See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a - complete list of overrideable properties. Be sure to also - check out inherited properties of `LinkView`. - - ### Overriding Application-wide Defaults - ``{{link-to}}`` creates an instance of Ember.LinkView - for rendering. To override options for your entire - application, reopen Ember.LinkView and supply the - desired values: - - ``` javascript - Ember.LinkView.reopen({ - activeClass: "is-active", - tagName: 'li' - }) - ``` - - It is also possible to override the default event in - this manner: - - ``` javascript - Ember.LinkView.reopen({ - eventName: 'customEventName' - }); - ``` - - @method link-to - @for Ember.Handlebars.helpers - @param {String} routeName - @param {Object} [context]* - @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkView - @return {String} HTML string - @see {Ember.LinkView} - */ - function linkToHelper(name) { - var options = slice.call(arguments, -1)[0]; - var params = slice.call(arguments, 0, -1); - var view = options.data.view; - var hash = options.hash; - var hashTypes = options.hashTypes; - var types = options.types; - var shouldEscape = !hash.unescaped; - var queryParamsObject; - - Ember.assert("You must provide one or more parameters to the link-to helper.", params.length); - - if (params[params.length - 1] instanceof QueryParams) { - hash.queryParamsObject = queryParamsObject = params.pop(); - } - - if (hash.disabledWhen) { - hash.disabledBinding = hash.disabledWhen; - hashTypes.disabledBinding = hashTypes.disabledWhen; - delete hash.disabledWhen; - delete hashTypes.disabledWhen; - } - - if (!options.fn) { - var linkTitle = params.shift(); - var linkTitleType = types.shift(); - if (linkTitleType === 'ID') { - hash.linkTitle = linkTitle = view.getStream(linkTitle); - options.fn = function() { - return stringifyValue(linkTitle.value(), shouldEscape); - }; - } else { - options.fn = function() { - return linkTitle; - }; - } - } - - // Setup route & param streams - for (var i = 0; i < params.length; i++) { - var paramPath = params[i]; - if (types[i] === 'ID') { - var lazyValue = view.getStream(paramPath); - - // TODO: Consider a better approach to unwrapping controllers. - if (paramPath !== 'controller') { - while (ControllerMixin.detect(lazyValue.value())) { - paramPath = (paramPath === '') ?

- }); - }); - - App.Router.reopen({ - location: 'hash' - }); - ``` - - This will result in a posts.new url of `/#/posts/new`. - - ### HistoryLocation - - Using `HistoryLocation` results in URLs that are indistinguishable from a - standard URL. This relies upon the browser's `history` API. - - Example: - - ```javascript - App.Router.map(function() { - this.resource('posts', function() { - this.route('new'); - }); - }); - - App.Router.reopen({ - location: 'history' - }); - ``` - - This will result in a posts.new url of `/posts/new`. - - Keep in mind that your server must serve the Ember app at all the routes you - define. - - ### AutoLocation - - Using `AutoLocation`, the router will use the best Location class supported by - the browser it is running in. - - Browsers that support the `history` API will use `HistoryLocation`, those that - do not, but still support the `hashchange` event will use `HashLocation`, and - in the rare case neither is supported will use `NoneLocation`. - - Example: - - ```javascript - App.Router.map(function() { - this.resource('posts', function() { - this.route('new'); - }); - }); - - App.Router.reopen({ - location: 'auto' - }); - ``` - - This will result in a posts.new url of `/posts/new` for modern browsers that - support the `history` api or `/#/posts/new` for older ones, like Internet - Explorer 9 and below. - - When a user visits a link to your application, they will be automatically - upgraded or downgraded to the appropriate `Location` class, with the URL - transformed accordingly, if needed. - - Keep in mind that since some of your users will use `HistoryLocation`, your - server must serve the Ember app at all the routes you define. - - ### NoneLocation - - Using `NoneLocation` causes Ember to not store the applications URL state - in the actual URL. This is generally used for testing purposes, and is one - of the changes made when calling `App.setupForTesting()`. - - ## Location API - - Each location implementation must provide the following methods: - - * implementation: returns the string name used to reference the implementation. - * getURL: returns the current URL. - * setURL(path): sets the current URL. - * replaceURL(path): replace the current URL (optional). - * onUpdateURL(callback): triggers the callback when the URL changes. - * formatURL(url): formats `url` to be placed into `href` attribute. - - Calling setURL or replaceURL will not trigger onUpdateURL callbacks. - - @class Location - @namespace Ember - @static - */ - __exports__["default"] = { - /** - This is deprecated in favor of using the container to lookup the location - implementation as desired. - - For example: - - ```javascript - // Given a location registered as follows: - container.register('location:history-test', HistoryTestLocation);

The last argument is - required to be an options object. The options object can have the - following three properties. - - `initialize` - An optional initialize function. Typically this will be used - to set up state on the instanceMeta object. - - `removedItem` - A function that is called each time an element is - removed from the array. - - `addedItem` - A function that is called each time an element is - added to the array. - - - The `initialize` function has the following signature: - - ```javascript - function(array, changeMeta, instanceMeta) - ``` - - `array` - The initial value of the arrayComputed, an empty array. - - `changeMeta` - An object which contains meta information about the - computed. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed. For example a - unique computed might use this to store the number of times a given - element is found in the dependent array. - - - The `removedItem` and `addedItem` functions both have the following signature: - - ```javascript - function(accumulatedValue, item, changeMeta, instanceMeta) - ``` - - `accumulatedValue` - The value returned from the last time - `removedItem` or `addedItem` was called or an empty array. - - `item` - the element added or removed from the array - - `changeMeta` - An object which contains meta information about the - change. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `index` the index of the added or removed item - - `item` the added or removed item: this is exactly the same as - the second arg - - `arrayChanged` the array that triggered the change. Can be - useful when depending on multiple arrays. - - For property changes triggered on an item property change (when - depKey is something like `someArray.@each.someProperty`), - `changeMeta` will also contain the following property: - - - `previousValues` an object whose keys are the properties that changed on - the item, and whose values are the item's previous values. - - `previousValues` is important Ember coalesces item property changes via - Ember.run.once. This means that by the time removedItem gets called, item has - the new values, but you may need the previous value (eg for sorting & - filtering). - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed.

The last argument is - required to be an options object. The options object can have the - following four properties: - - `initialValue` - A value or function that will be used as the initial - value for the computed. If this property is a function the result of calling - the function will be used as the initial value. This property is required. - - `initialize` - An optional initialize function. Typically this will be used - to set up state on the instanceMeta object. - - `removedItem` - A function that is called each time an element is removed - from the array. - - `addedItem` - A function that is called each time an element is added to - the array. - - - The `initialize` function has the following signature: - - ```javascript - function(initialValue, changeMeta, instanceMeta) - ``` - - `initialValue` - The value of the `initialValue` property from the - options object. - - `changeMeta` - An object which contains meta information about the - computed. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed. For example a - unique computed might use this to store the number of times a given - element is found in the dependent array. - - - The `removedItem` and `addedItem` functions both have the following signature: - - ```javascript - function(accumulatedValue, item, changeMeta, instanceMeta) - ``` - - `accumulatedValue` - The value returned from the last time - `removedItem` or `addedItem` was called or `initialValue`. - - `item` - the element added or removed from the array - - `changeMeta` - An object which contains meta information about the - change. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `index` the index of the added or removed item - - `item` the added or removed item: this is exactly the same as - the second arg - - `arrayChanged` the array that triggered the change. Can be - useful when depending on multiple arrays. - - For property changes triggered on an item property change (when - depKey is something like `someArray.@each.someProperty`), - `changeMeta` will also contain the following property: - - - `previousValues` an object whose keys are the properties that changed on - the item, and whose values are the item's previous values. - - `previousValues` is important Ember coalesces item property changes via - Ember.run.once. This means that by the time removedItem gets called, item has - the new values, but you may need the previous value (eg for sorting & - filtering). - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed. For example a - unique computed might use this to store the number of times a given - element is found in the dependent array. - - The `removedItem` and `addedItem` functions should return the accumulated - value. It is acceptable to not return anything (ie return undefined) - to invalidate the computation. This is generally not a good idea for - arrayComputed but it's used in eg max and min. - - Note that observers will be fired if either of these functions return a value - that differs from the accumulated value. When returning an object that - mutates in response to array changes, for example an array that maps - everything from some other array (see `Ember.computed.map`), it is usually - important that the *same* array be returned to avoid accidentally triggering observers. - - Example - - ```javascript - Ember.computed.max = function(dependentKey) { - return Ember.reduceComputed(dependentKey, { - initialValue: -Infinity, - - addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) { - return Math.max(accumulatedValue, item); - }, - - removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) { - if (item < accumulatedValue) { - return accumulatedValue; - } - } - }); - }; - ``` - - Dependent keys may refer to `@this` to observe changes to the object itself, - which must be array-like, rather than a property of the object. This is - mostly useful for array proxies, to ensure objects are retrieved via - `objectAtContent`. This is how you could sort items by properties defined on an item controller. - - Example - - ```javascript - App.PeopleController = Ember.ArrayController.extend({ - itemController: 'person', - - sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) { - // `reversedName` isn't defined on Person, but we have access to it via - // the item controller App.PersonController.

to change what's displayed, simply swap out the - `model` property on the controller. - - For example, imagine you wanted to display a list of items fetched via an XHR - request. Create an `Ember.ArrayController` and set its `model` property: - - ```javascript - MyApp.listController = Ember.ArrayController.create(); - - $.get('people.json', function(data) { - MyApp.listController.set('model', data); - }); - ``` - - Then, create a view that binds to your new controller: - - ```handlebars - {{#each person in MyApp.listController}} - {{person.firstName}} {{person.lastName}} - {{/each}} - ``` - - Although you are binding to the controller, the behavior of this controller - is to pass through any methods or properties to the underlying array. This - capability comes from `Ember.ArrayProxy`, which this class inherits from. - - Sometimes you want to display computed properties within the body of an - `#each` helper that depend on the underlying items in `model`, but are not - present on those items. To do this, set `itemController` to the name of a - controller (probably an `ObjectController`) that will wrap each individual item. - - For example: - - ```handlebars - {{#each post in controller}} - <li>{{post.title}} ({{post.titleLength}} characters)</li> - {{/each}} - ``` - - ```javascript - App.PostsController = Ember.ArrayController.extend({ - itemController: 'post' - }); - - App.PostController = Ember.ObjectController.extend({ - // the `title` property will be proxied to the underlying post. - titleLength: function() { - return this.get('title').length; - }.property('title') - }); - ``` - - In some cases it is helpful to return a different `itemController` depending - on the particular item. Subclasses can do this by overriding - `lookupItemController`. - - For example: - - ```javascript - App.MyArrayController = Ember.ArrayController.extend({ - lookupItemController: function( object ) { - if (object.get('isSpecial')) { - return "special"; // use App.SpecialController - } else { - return "regular"; // use App.RegularController - } - } - }); - ``` - - The itemController instances will have a `parentController` property set to - the `ArrayController` instance. - - @class ArrayController - @namespace Ember - @extends Ember.ArrayProxy - @uses Ember.SortableMixin - @uses Ember.ControllerMixin - */ - - __exports__["default"] = ArrayProxy.extend(ControllerMixin, SortableMixin, { - - /** - The controller used to wrap items, if any.

This is one of the fundamental ways that - models, controllers and views communicate with each other in an Ember - application. - - Any object that has this mixin applied can be used in observer - operations. That includes `Ember.Object` and most objects you will - interact with as you write your Ember application. - - Note that you will not generally apply this mixin to classes yourself, - but you will use the features provided by this module frequently, so it - is important to understand how to use it. - - ## Using `get()` and `set()` - - Because of Ember's support for bindings and observers, you will always - access properties using the get method, and set properties using the - set method. This allows the observing objects to be notified and - computed properties to be handled properly. - - More documentation about `get` and `set` are below. - - ## Observing Property Changes - - You typically observe property changes simply by adding the `observes` - call to the end of your method declarations in classes that you write. - For example: - - ```javascript - Ember.Object.extend({ - valueObserver: function() { - // Executes whenever the "value" property changes - }.observes('value') - }); - ``` - - Although this is the most common way to add an observer, this capability - is actually built into the `Ember.Object` class on top of two methods - defined in this mixin: `addObserver` and `removeObserver`. You can use - these two methods to add and remove observers yourself if you need to - do so at runtime. - - To add an observer for a property, call: - - ```javascript - object.addObserver('propertyKey', targetObject, targetAction) - ``` - - This will call the `targetAction` method on the `targetObject` whenever - the value of the `propertyKey` changes. - - Note that if `propertyKey` is a computed property, the observer will be - called when any of the property dependencies are changed, even if the - resulting value of the computed property is unchanged. This is necessary - because computed properties are not computed until `get` is called. - - @class Observable - @namespace Ember - */ - __exports__["default"] = Mixin.create({ - - /** - Retrieves the value of a property from the object. - - This method is usually similar to using `object[keyName]` or `object.keyName`, - however it supports both computed properties and the unknownProperty - handler. - - Because `get` unifies the syntax for accessing all these kinds - of properties, it can make many refactorings easier, such as replacing a - simple property with a computed property, or vice versa. - - ### Computed Properties - - Computed properties are methods defined with the `property` modifier - declared at the end, such as: - - ```javascript - fullName: function() { - return this.get('firstName') + ' ' + this.get('lastName'); - }.property('firstName', 'lastName') - ``` - - When you call `get` on a computed property, the function will be - called and the return value will be returned instead of the function - itself. - - ### Unknown Properties - - Likewise, if you try to call `get` on a property whose value is - `undefined`, the `unknownProperty()` method will be called on the object. - If this method returns any value other than `undefined`, it will be returned - instead. This allows you to implement "virtual" properties that are - not defined upfront. - - @method get - @param {String} keyName The property to retrieve - @return {Object} The property value or undefined. - */ - get: function(keyName) { - return get(this, keyName); - }, - - /** - To get the values of multiple properties at once, call `getProperties` - with a list of strings or an array: - - ```javascript - record.getProperties('firstName', 'lastName', 'zipCode'); - // { firstName: 'John', lastName: 'Doe', zipCode: '10011' } - ``` - - is equivalent to: - - ```javascript - record.getProperties(['firstName', 'lastName', 'zipCode']); - // { firstName: 'John', lastName: 'Doe', zipCode: '10011' } - ``` - - @method getProperties - @param {String...|Array} list of keys to get - @return {Hash} - */ - getProperties: function() { - return apply(null, getProperties, [this].concat(slice.call(arguments))); - }, - - /** - Sets the provided key or path to the value. - - This method is generally very similar to calling `object[key] = value` or - `object.key = value`, except that it provides support for computed - properties, the `setUnknownProperty()` method and property observers. - - ### Computed Properties - - If you try to set a value on a key that has a computed property handler - defined (see the `get()` method for an example), then `set()` will call - that method, passing both the value and key instead of simply changing - the value itself. This is useful for those times when you need to - implement a property that is composed of one or more member - properties. - - ### Unknown Properties - - If you try to set a value on a key that is undefined in the target - object, then the `setUnknownProperty()` handler will be called instead. This - gives you an opportunity to implement complex "virtual" properties that - are not predefined on the object. If `setUnknownProperty()` returns - undefined, then `set()` will simply set the value on the object. - - ### Property Observers - - In addition to changing the property, `set()` will also register a property - change with the object. Unless you have placed this call inside of a - `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers - (i.e. observer methods declared on the same object), will be called - immediately. Any "remote" observers (i.e. observer methods declared on - another object) will be placed in a queue and called at a later time in a - coalesced manner. - - ### Chaining - - In addition to property changes, `set()` returns the value of the object - itself so you can do chaining like this: - - ```javascript - record.set('firstName', 'Charles').set('lastName', 'Jolley'); - ``` - - @method set - @param {String} keyName The property to set - @param {Object} value The value to set or `null`. - @return {Ember.Observable} - */ - set: function(keyName, value) { - set(this, keyName, value); - return this; - }, - - - /** - Sets a list of properties at once.

The - context will be passed to your observer method whenever it is triggered. - Note that if you add the same target/method pair on a key multiple times - with different context parameters, your observer will only be called once - with the last context you passed. - - ### Observer Methods - - Observer methods you pass should generally have the following signature if - you do not pass a `context` parameter: - - ```javascript - fooDidChange: function(sender, key, value, rev) { }; - ``` - - The sender is the object that changed. The key is the property that - changes. The value property is currently reserved and unused. The rev - is the last property revision of the object when it changed, which you can - use to detect if the key value has really changed or not. - - If you pass a `context` parameter, the context will be passed before the - revision like so: - - ```javascript - fooDidChange: function(sender, key, value, context, rev) { }; - ``` - - Usually you will not need the value, context or revision parameters at - the end. In this case, it is common to write observer methods that take - only a sender and key value as parameters or, if you aren't interested in - any of these values, to write an observer that has no parameters at all. - - @method addObserver - @param {String} key The key to observer - @param {Object} target The target object to invoke - @param {String|Function} method The method to invoke. - */ - addObserver: function(key, target, method) { - addObserver(this, key, target, method); - }, - - /** - Remove an observer you have previously registered on this object.

Any instance of the `App.Person` class will *not* have the `march()` method. - - You can also pass `Mixin` classes to add additional properties to the subclass. - - ```javascript - App.Person = Ember.Object.extend({ - say: function(thing) { - alert(this.get('name') + ' says: ' + thing); - } - }); - - App.SingingMixin = Mixin.create({ - sing: function(thing){ - alert(this.get('name') + ' sings: la la la ' + thing); - } - }); - - App.BroadwayStar = App.Person.extend(App.SingingMixin, { - dance: function() { - alert(this.get('name') + ' dances: tap tap tap tap '); - } - }); - ``` - - The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`. - - @method extend - @static - - @param {Mixin} [mixins]* One or more Mixin classes - @param {Object} [arguments]* Object containing values to use within the new class - */ - extend: function extend() { - var Class = makeCtor(); - var proto; - Class.ClassMixin = Mixin.create(this.ClassMixin); - Class.PrototypeMixin = Mixin.create(this.PrototypeMixin); - - Class.ClassMixin.ownerConstructor = Class; - Class.PrototypeMixin.ownerConstructor = Class; - - reopen.apply(Class.PrototypeMixin, arguments); - - Class.superclass = this; - Class.__super__ = this.prototype; - - proto = Class.prototype = o_create(this.prototype); - proto.constructor = Class; - generateGuid(proto); - meta(proto).proto = proto; // this will disable observers on prototype - - Class.ClassMixin.apply(Class); - return Class; - }, - - /** - Equivalent to doing `extend(arguments).create()`. - If possible use the normal `create` method instead. - - @method createWithMixins - @static - @param [arguments]* - */ - createWithMixins: function() { - var C = this; - var l= arguments.length; - if (l > 0) { - var args = new Array(l); - for (var i = 0; i < l; i++) { - args[i] = arguments[i]; - } - this._initMixins(args); - } - return new C(); - }, - - /** - Creates an instance of a class.

You - can create a set to efficiently test for membership for an object. You can - also iterate through a set just like an array, even accessing objects by - index, however there is no guarantee as to their order. - - All Sets are observable via the Enumerable Observer API - which works - on any enumerable object including both Sets and Arrays. - - ## Creating a Set - - You can create a set like you would most objects using - `new Ember.Set()`. Most new sets you create will be empty, but you can - also initialize the set with some content by passing an array or other - enumerable of objects to the constructor. - - Finally, you can pass in an existing set and the set will be copied. You - can also create a copy of a set by calling `Ember.Set#copy()`. - - ```javascript - // creates a new empty set - var foundNames = new Ember.Set(); - - // creates a set with four names in it. - var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P - - // creates a copy of the names set. - var namesCopy = new Ember.Set(names); - - // same as above. - var anotherNamesCopy = names.copy(); - ``` - - ## Adding/Removing Objects - - You generally add or remove objects from a set using `add()` or - `remove()`. You can add any type of object including primitives such as - numbers, strings, and booleans. - - Unlike arrays, objects can only exist one time in a set. If you call `add()` - on a set with the same object multiple times, the object will only be added - once. Likewise, calling `remove()` with the same object multiple times will - remove the object the first time and have no effect on future calls until - you add the object to the set again. - - NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do - so will be ignored. - - In addition to add/remove you can also call `push()`/`pop()`. Push behaves - just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary - object, remove it and return it. This is a good way to use a set as a job - queue when you don't care which order the jobs are executed in. - - ## Testing for an Object - - To test for an object's presence in a set you simply call - `Ember.Set#contains()`. - - ## Observing changes - - When using `Ember.Set`, you can observe the `"[]"` property to be - alerted whenever the content changes. You can also add an enumerable - observer to the set to be notified of specific objects that are added and - removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html) - for more information on enumerables. - - This is often unhelpful. If you are filtering sets of objects, for instance, - it is very inefficient to re-filter all of the items each time the set - changes. It would be better if you could just adjust the filtered set based - on what was changed on the original set. The same issue applies to merging - sets, as well. - - ## Other Methods - - `Ember.Set` primary implements other mixin APIs. For a complete reference - on the methods you will use with `Ember.Set`, please consult these mixins. - The most useful ones will be `Ember.Enumerable` and - `Ember.MutableEnumerable` which implement most of the common iterator - methods you are used to on Array. - - Note that you can also use the `Ember.Copyable` and `Ember.Freezable` - APIs on `Ember.Set` as well. Once a set is frozen it can no longer be - modified. The benefit of this is that when you call `frozenCopy()` on it, - Ember will avoid making copies of the set. This allows you to write - code that can know with certainty when the underlying set data will or - will not be modified. - - @class Set - @namespace Ember - @extends Ember.CoreObject - @uses Ember.MutableEnumerable - @uses Ember.Copyable - @uses Ember.Freezable - @since Ember 0.9 - @deprecated - */ - __exports__["default"] = CoreObject.extend(MutableEnumerable, Copyable, Freezable, { - - // .......................................................... - // IMPLEMENT ENUMERABLE APIS - // - - /** - This property will change as the number of objects in the set changes. - - @property length - @type number - @default 0 - */ - length: 0, - - /** - Clears the set.

This - can be customized by setting the `tagName` property. The following view - class: - - ```javascript - ParagraphView = Ember.View.extend({ - tagName: 'em' - }); - ``` - - Would result in instances with the following HTML: - - ```html - <em id="ember1" class="ember-view"></em> - ``` - - ## HTML `class` Attribute - - The HTML `class` attribute of a view's tag can be set by providing a - `classNames` property that is set to an array of strings: - - ```javascript - MyView = Ember.View.extend({ - classNames: ['my-class', 'my-other-class'] - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view my-class my-other-class"></div> - ``` - - `class` attribute values can also be set by providing a `classNameBindings` - property set to an array of properties names for the view. The return value - of these properties will be added as part of the value for the view's `class` - attribute. These properties can be computed properties: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['propertyA', 'propertyB'], - propertyA: 'from-a', - propertyB: function() { - if (someLogic) { return 'from-b'; } - }.property() - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view from-a from-b"></div> - ``` - - If the value of a class name binding returns a boolean the property name - itself will be used as the class name if the property is true. The class name - will not be added if the value is `false` or `undefined`. - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['hovered'], - hovered: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view hovered"></div> - ``` - - When using boolean class name bindings you can supply a string value other - than the property name for use as the `class` HTML attribute by appending the - preferred value after a ":" character when defining the binding: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['awesome:so-very-cool'], - awesome: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view so-very-cool"></div> - ``` - - Boolean value class name bindings whose property names are in a - camelCase-style format will be converted to a dasherized format: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['isUrgent'], - isUrgent: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view is-urgent"></div> - ``` - - Class name bindings can also refer to object values that are found by - traversing a path relative to the view itself: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['messages.empty'] - messages: Ember.Object.create({ - empty: true - }) - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view empty"></div> - ``` - - If you want to add a class name for a property which evaluates to true and - and a different class name if it evaluates to false, you can pass a binding - like this: - - ```javascript - // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled:enabled:disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view enabled"></div> - ``` - - When isEnabled is `false`, the resulting HTML reprensentation looks like - this: - - ```html - <div id="ember1" class="ember-view disabled"></div> - ``` - - This syntax offers the convenience to add a class if a property is `false`: - - ```javascript - // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled::disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view"></div> - ``` - - When the `isEnabled` property on the view is set to `false`, it will result - in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view disabled"></div> - ``` - - Updates to the the value of a class name binding will result in automatic - update of the HTML `class` attribute in the view's rendered HTML - representation. If the value becomes `false` or `undefined` the class name - will be removed. - - Both `classNames` and `classNameBindings` are concatenated properties. See - [Ember.Object](/api/classes/Ember.Object.html) documentation for more - information about concatenated properties. - - ## HTML Attributes - - The HTML attribute section of a view's tag can be set by providing an - `attributeBindings` property set to an array of property names on the view. - The return value of these properties will be used as the value of the view's - HTML associated attribute: - - ```javascript - AnchorView = Ember.View.extend({ - tagName: 'a', - attributeBindings: ['href'], - href: 'http://google.com' - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <a id="ember1" class="ember-view" href="http://google.com"></a> - ``` - - One property can be mapped on to another by placing a ":" between - the source property and the destination property: - - ```javascript - AnchorView = Ember.View.extend({ - tagName: 'a', - attributeBindings: ['url:href'], - url: 'http://google.com' - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <a id="ember1" class="ember-view" href="http://google.com"></a> - ``` - - If the return value of an `attributeBindings` monitored property is a boolean - the property will follow HTML's pattern of repeating the attribute's name as - its value: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <input id="ember1" class="ember-view" disabled="disabled" /> - ``` - - `attributeBindings` can refer to computed properties: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: function() { - if (someLogic) { - return true; - } else { - return false; - } - }.property() - }); - ``` - - Updates to the the property of an attribute binding will result in automatic - update of the HTML attribute in the view's rendered HTML representation. - - `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) - documentation for more information about concatenated properties. - - ## Templates - - The HTML contents of a view's rendered representation are determined by its - template. Templates can be any function that accepts an optional context - parameter and returns a string of HTML that will be inserted within the - view's tag. Most typically in Ember this function will be a compiled - `Ember.Handlebars` template. - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('I am the template') - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view">I am the template</div> - ``` - - Within an Ember application is more common to define a Handlebars templates as - part of a page: - - ```html - <script type='text/x-handlebars' data-template-name='some-template'> - Hello - </script> - ``` - - And associate it by name using a view's `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'some-template' - }); - ``` - - If you have nested resources, your Handlebars template will look like this: - - ```html - <script type='text/x-handlebars' data-template-name='posts/new'> - <h1>New Post</h1> - </script> - ``` - - And `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'posts/new' - }); - ``` - - Using a value for `templateName` that does not have a Handlebars template - with a matching `data-template-name` attribute will throw an error. - - For views classes that may have a template later defined (e.g. as the block - portion of a `{{view}}` Handlebars helper call in another template or in - a subclass), you can provide a `defaultTemplate` property set to compiled - template function. If a template is not later provided for the view instance - the `defaultTemplate` value will be used: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default'), - template: null, - templateName: null - }); - ``` - - Will result in instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view">I was the default</div> - ``` - - If a `template` or `templateName` is provided it will take precedence over - `defaultTemplate`: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default') - }); - - aView = AView.create({ - template: Ember.Handlebars.compile('I was the template, not default') - }); - ``` - - Will result in the following HTML representation when rendered: - - ```html - <div id="ember1" class="ember-view">I was the template, not default</div> - ``` - - ## View Context - - The default context of the compiled template is the view's controller: - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') - }); - - aController = Ember.Object.create({ - firstName: 'Barry', - excitedGreeting: function() { - return this.get("content.firstName") + "!!!" - }.property() - }); - - aView = AView.create({ - controller: aController - }); - ``` - - Will result in an HTML representation of: - - ```html - <div id="ember1" class="ember-view">Hello Barry!!!</div> - ``` - - A context can also be explicitly supplied through the view's `context` - property. If the view has neither `context` nor `controller` properties, the - `parentView`'s context will be used. - - ## Layouts - - Views can have a secondary template that wraps their main template. Like - primary templates, layouts can be any function that accepts an optional - context parameter and returns a string of HTML that will be inserted inside - view's tag. Views whose HTML element is self closing (e.g. `<input />`) - cannot have a layout and this property will be ignored. - - Most typically in Ember a layout will be a compiled `Ember.Handlebars` - template. - - A view's layout can be set directly with the `layout` property or reference - an existing Handlebars template by name with the `layoutName` property. - - A template used as a layout must contain a single use of the Handlebars - `{{yield}}` helper. The HTML contents of a view's rendered `template` will be - inserted at this location: - - ```javascript - AViewWithLayout = Ember.View.extend({ - layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>"), - template: Ember.Handlebars.compile("I got wrapped") - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - <div id="ember1" class="ember-view"> - <div class="my-decorative-class"> - I got wrapped - </div> - </div> - ``` - - See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) - for more information. - - ## Responding to Browser Events - - Views can respond to user-initiated events in one of three ways: method - implementation, through an event manager, and through `{{action}}` helper use - in their template or layout. - - ### Method Implementation - - Views can respond to user-initiated events by implementing a method that - matches the event name. A `jQuery.Event` object will be passed as the - argument to this method. - - ```javascript - AView = Ember.View.extend({ - click: function(event) { - // will be called when when an instance's - // rendered element is clicked - } - }); - ``` - - ### Event Managers - - Views can define an object as their `eventManager` property. This object can - then implement methods that match the desired event names. Matching events - that occur on the view's rendered HTML or the rendered HTML of any of its DOM - descendants will trigger this method. A `jQuery.Event` object will be passed - as the first argument to the method and an `Ember.View` object as the - second. The `Ember.View` will be the view whose rendered HTML was interacted - with. This may be the view with the `eventManager` property or one of its - descendent views. - - ```javascript - AView = Ember.View.extend({ - eventManager: Ember.Object.create({ - doubleClick: function(event, view) { - // will be called when when an instance's - // rendered element or any rendering - // of this views's descendent - // elements is clicked - } - }) - }); - ``` - - An event defined for an event manager takes precedence over events of the - same name handled through methods on the view. - - ```javascript - AView = Ember.View.extend({ - mouseEnter: function(event) { - // will never trigger. - }, - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // takes precedence over AView#mouseEnter - } - }) - }); - ``` - - Similarly a view's event manager will take precedence for events of any views - rendered as a descendent. A method name that matches an event name will not - be called if the view instance was rendered inside the HTML representation of - a view that has an `eventManager` property defined that handles events of the - name. Events not handled by the event manager will still trigger method calls - on the descendent. - - ```javascript - var App = Ember.Application.create(); - App.OuterView = Ember.View.extend({ - template: Ember.Handlebars.compile("outer {{#view 'inner'}}inner{{/view}} outer"), - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // view might be instance of either - // OuterView or InnerView depending on - // where on the page the user interaction occured - } - }) - }); - - App.InnerView = Ember.View.extend({ - click: function(event) { - // will be called if rendered inside - // an OuterView because OuterView's - // eventManager doesn't handle click events - }, - mouseEnter: function(event) { - // will never be called if rendered inside - // an OuterView. - } - }); - ``` - - ### Handlebars `{{action}}` Helper - - See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). - - ### Event Names - - All of the event handling approaches described above respond to the same set - of events.

For example, - `denodeify` transforms the following: - - ```javascript - var fs = require('fs'); - - fs.readFile('myfile.txt', function(err, data){ - if (err) return handleError(err); - handleData(data); - }); - ``` - - into: - - ```javascript - var fs = require('fs'); - var readFile = RSVP.denodeify(fs.readFile); - - readFile('myfile.txt').then(handleData, handleError); - ``` - - If the node function has multiple success parameters, then `denodeify` - just returns the first one: - - ```javascript - var request = RSVP.denodeify(require('request')); - - request('http://example.com').then(function(res) { - // ... - }); - ``` - - However, if you need all success parameters, setting `denodeify`'s - second parameter to `true` causes it to return all success parameters - as an array: - - ```javascript - var request = RSVP.denodeify(require('request'), true); - - request('http://example.com').then(function(result) { - // result[0] -> res - // result[1] -> body - }); - ``` - - Or if you pass it an array with names it returns the parameters as a hash: - - ```javascript - var request = RSVP.denodeify(require('request'), ['res', 'body']); - - request('http://example.com').then(function(result) { - // result.res - // result.body - }); - ``` - - Sometimes you need to retain the `this`: - - ```javascript - var app = require('express')(); - var render = RSVP.denodeify(app.render.bind(app)); - ``` - - The denodified function inherits from the original function. It works in all - environments, except IE 10 and below. Consequently all properties of the original - function are available to you. However, any properties you change on the - denodeified function won't be changed on the original function. Example: - - ```javascript - var request = RSVP.denodeify(require('request')), - cookieJar = request.jar(); // <- Inheritance is used here - - request('http://example.com', {jar: cookieJar}).then(function(res) { - // cookieJar.cookies holds now the cookies returned by example.com - }); - ``` - - Using `denodeify` makes it easier to compose asynchronous operations instead - of using callbacks. For example, instead of: - - ```javascript - var fs = require('fs'); - - fs.readFile('myfile.txt', function(err, data){ - if (err) { ... } // Handle error - fs.writeFile('myfile2.txt', data, function(err){ - if (err) { ... } // Handle error - console.log('done') - }); - }); - ``` - - you can chain the operations together using `then` from the returned promise: - - ```javascript - var fs = require('fs'); - var readFile = RSVP.denodeify(fs.readFile); - var writeFile = RSVP.denodeify(fs.writeFile); - - readFile('myfile.txt').then(function(data){ - return writeFile('myfile2.txt', data); - }).then(function(){ - console.log('done') - }).catch(function(error){ - // Handle error - }); - ``` - - @method denodeify - @static - @for RSVP - @param {Function} nodeFunc a 'node-style' function that takes a callback as - its last argument. The callback expects an error to be passed as its first - argument (if an error occurred, otherwise null), and the value from the - operation as its second argument ('function(err, value){ }'). - @param {Boolean|Array} argumentNames An optional paramter that if set - to `true` causes the promise to fulfill with the callback's success arguments - as an array. This is useful if the node function has multiple success - paramters. If you set this paramter to an array with names, the promise will - fulfill with a hash with these names as keys and the success parameters as - values. - @return {Function} a function that wraps `nodeFunc` to return an - `RSVP.Promise` - @static - */ - __exports__["default"] = function denodeify(nodeFunc, options) { - var fn = function() { - var self = this; - var l = arguments.length; - var args = new Array(l + 1); - var arg; - var promiseInput = false; - - for (var i = 0; i < l; ++i) { - arg = arguments[i]; - - if (!promiseInput) { - // TODO: clean this up - promiseInput = needsPromiseInput(arg); - if (promiseInput === GET_THEN_ERROR) { - var p = new Promise(noop); - reject(p, GET_THEN_ERROR.value); - return p; - } else if (promiseInput && promiseInput !== true) { - arg = wrapThenable(promiseInput, arg); - } - } - args[i] = arg; - } - - var promise = new Promise(noop); - - args[l] = function(err, val) { - if (err) - reject(promise, err); - else if (options === undefined) - resolve(promise, val); - else if (options === true) - resolve(promise, arrayResult(arguments)); - else if (isArray(options)) - resolve(promise, makeObject(arguments, options)); - else - resolve(promise, val); - }; - - if (promiseInput) { - return handlePromiseInput(promise, args, nodeFunc, self); - } else { - return handleValueInput(promise, args, nodeFunc, self); - } - }; - - fn.__proto__ = nodeFunc; - - return fn; - } - - function handleValueInput(promise, args, nodeFunc, self) { - var result = tryApply(nodeFunc, self, args); - if (result === ERROR) { - reject(promise, result.value); - } - return promise; - } - - function handlePromiseInput(promise, args, nodeFunc, self){ - return Promise.all(args).then(function(args){ - var result = tryApply(nodeFunc, self, args); - if (result === ERROR) { - reject(promise, result.value); - } - return promise; - }); - } - - function needsPromiseInput(arg) { - if (arg && typeof arg === 'object') { - if (arg.constructor === Promise) { - return true; - } else { - return getThen(arg); - } - } else { - return false; - } - } - }); -enifed("rsvp/promise-hash", - ["./enumerator","./-internal","./utils","exports"], - function(__dependency1__, __dependency2__, __dependency3__, __exports__) { - "use strict"; - var Enumerator = __dependency1__["default"]; - var PENDING = __dependency2__.PENDING; - var o_create = __dependency3__.o_create; - - function PromiseHash(Constructor, object, label) { - this._superConstructor(Constructor, object, true, label); - } - - __exports__["default"] = PromiseHash; - - PromiseHash.prototype = o_create(Enumerator.prototype); - PromiseHash.prototype._superConstructor = Enumerator; - PromiseHash.prototype._init = function() { - this._result = {}; - }; - - PromiseHash.prototype._validateInput = function(input) { - return input && typeof input === 'object'; - }; - - PromiseHash.prototype._validationError = function() { - return new Error('Promise.hash must be called with an object'); - }; - - PromiseHash.prototype._enumerate = function() { - var promise = this.promise; - var input = this._input; - var results = []; - - for (var key in input) { - if (promise._state === PENDING && input.hasOwnProperty(key)) { - results.push({ - position: key, - entry: input[key] - }); - } - } - - var length = results.length; - this._remaining = length; - var result; - - for (var i = 0; promise._state === PENDING && i < length; i++) { - result = results[i]; - this._eachEntry(result.entry, result.position); - } - }; - }); -enifed("rsvp/promise", - ["./config","./instrument","./utils","./-internal","./promise/all","./promise/race","./promise/resolve","./promise/reject","exports"], - function(__dependency1__, __dependency2__, __dependency3__, __dependency4__, __dependency5__, __dependency6__, __dependency7__, __dependency8__, __exports__) { - "use strict"; - var config = __dependency1__.config; - var instrument = __dependency2__["default"]; - - var isFunction = __dependency3__.isFunction; - var now = __dependency3__.now; - - var noop = __dependency4__.noop; - var subscribe = __dependency4__.subscribe; - var initializePromise = __dependency4__.initializePromise; - var invokeCallback = __dependency4__.invokeCallback; - var FULFILLED = __dependency4__.FULFILLED; - var REJECTED = __dependency4__.REJECTED; - - var all = __dependency5__["default"]; - var race = __dependency6__["default"]; - var Resolve = __dependency7__["default"]; - var Reject = __dependency8__["default"]; - - var guidKey = 'rsvp_' + now() + '-'; - var counter = 0; - - function needsResolver() { - throw new TypeError('You must pass a resolver function as the first argument to the promise constructor'); - } - - function needsNew() { - throw new TypeError("Failed to construct 'Promise': Please use the 'new' operator, this object constructor cannot be called as a function."); - } - __exports__["default"] = Promise; - /** - Promise objects represent the eventual result of an asynchronous operation. The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise’s eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class RSVP.Promise - @param {function} resolver - @param {String} label optional string for labeling the promise. - Useful for tooling. - @constructor - */ - function Promise(resolver, label) { - this._id = counter++; - this._label = label; - this._state = undefined; - this._result = undefined; - this._subscribers = []; - - if (config.instrument) { - instrument('created', this); - } - - if (noop !== resolver) { - if (!isFunction(resolver)) { - needsResolver(); - } - - if (!(this instanceof Promise)) { - needsNew(); - } - - initializePromise(this, resolver); - } - } - - Promise.cast = Resolve; // deprecated - Promise.all = all; - Promise.race = race; - Promise.resolve = Resolve; - Promise.reject = Reject; - - Promise.prototype = { - constructor: Promise, - - _guidKey: guidKey, - - _onerror: function (reason) { - config.trigger('error', reason); - }, - - /** - The primary way of interacting with a promise is through its `then` method, - which registers callbacks to receive either a promise's eventual value or the - reason why the promise cannot be fulfilled. - - ```js - findUser().then(function(user){ - // user is available - }, function(reason){ - // user is unavailable, and you are given the reason why - }); - ``` - - Chaining - -------- - - The return value of `then` is itself a promise. This second, 'downstream' - promise is resolved with the return value of the first promise's fulfillment - or rejection handler, or rejected if the handler throws an exception. - - ```js - findUser().then(function (user) { - return user.name; - }, function (reason) { - return 'default name'; - }).then(function (userName) { - // If `findUser` fulfilled, `userName` will be the user's name, otherwise it - // will be `'default name'` - }); - - findUser().then(function (user) { - throw new Error('Found user, but still unhappy'); - }, function (reason) { - throw new Error('`findUser` rejected and we're unhappy'); - }).then(function (value) { - // never reached - }, function (reason) { - // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. - // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. - }); - ``` - If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. - - ```js - findUser().then(function (user) { - throw new PedagogicalException('Upstream error'); - }).then(function (value) { - // never reached - }).then(function (value) { - // never reached - }, function (reason) { - // The `PedgagocialException` is propagated all the way down to here - }); - ``` - - Assimilation - ------------ - - Sometimes the value you want to propagate to a downstream promise can only be - retrieved asynchronously. This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // If `findCommentsByAuthor` fulfills, we'll have the value here - }, function (reason) { - // If `findCommentsByAuthor` rejects, we'll have the reason here - }); - ``` - - Simple Example - -------------- - - Synchronous Example - - ```javascript - var result; - - try { - result = findResult(); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - findResult(function(result, err){ - if (err) { - // failure - } else { - // success - } - }); - ``` - - Promise Example; - - ```javascript - findResult().then(function(result){ - // success - }, function(reason){ - // failure - }); - ``` - - Advanced Example - -------------- - - Synchronous Example - - ```javascript - var author, books; - - try { - author = findAuthor(); - books = findBooksByAuthor(author); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - - function foundBooks(books) { - - } - - function failure(reason) { - - } - - findAuthor(function(author, err){ - if (err) { - failure(err); - // failure - } else { - try { - findBoooksByAuthor(author, function(books, err) { - if (err) { - failure(err); - } else { - try { - foundBooks(books); - } catch(reason) { - failure(reason); - } - } - }); - } catch(error) { - failure(err); - } - // success - } - }); - ``` - - Promise Example; - - ```javascript - findAuthor(). - then(findBooksByAuthor). - then(function(books){ - // found books - }).catch(function(reason){ - // something went wrong - }); - ``` - - @method then - @param {Function} onFulfilled - @param {Function} onRejected - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - then: function(onFulfillment, onRejection, label) { - var parent = this; - var state = parent._state; - - if (state === FULFILLED && !onFulfillment || state === REJECTED && !onRejection) { - if (config.instrument) { - instrument('chained', this, this); - } - return this; - } - - parent._onerror = null; - - var child = new this.constructor(noop, label); - var result = parent._result; - - if (config.instrument) { - instrument('chained', parent, child); - } - - if (state) { - var callback = arguments[state - 1]; - config.async(function(){ - invokeCallback(state, child, callback, result); - }); - } else { - subscribe(parent, child, onFulfillment, onRejection); - } - - return child; - }, - - /** - `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same - as the catch block of a try/catch statement. - - ```js - function findAuthor(){ - throw new Error('couldn't find that author'); - } - - // synchronous - try { - findAuthor(); - } catch(reason) { - // something went wrong - } - - // async with promises - findAuthor().catch(function(reason){ - // something went wrong - }); - ``` - - @method catch - @param {Function} onRejection - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - 'catch': function(onRejection, label) { - return this.then(null, onRejection, label); - }, - - /** - `finally` will be invoked regardless of the promise's fate just as native - try/catch/finally behaves - - Synchronous example: - - ```js - findAuthor() { - if (Math.random() > 0.5) { - throw new Error(); - } - return new Author(); - } - - try { - return findAuthor(); // succeed or fail - } catch(error) { - return findOtherAuther(); - } finally { - // always runs - // doesn't affect the return value - } - ``` - - Asynchronous example: - - ```js - findAuthor().catch(function(reason){ - return findOtherAuther(); - }).finally(function(){ - // author was either found, or not - }); - ``` - - @method finally - @param {Function} callback - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - 'finally': function(callback, label) { - var constructor = this.constructor; - - return this.then(function(value) { - return constructor.resolve(callback()).then(function(){ - return value; - }); - }, function(reason) { - return constructor.resolve(callback()).then(function(){ - throw reason; - }); - }, label); - } - }; - }); -enifed("rsvp/promise/all", - ["../enumerator","exports"], - function(__dependency1__, __exports__) { - "use strict"; - var Enumerator = __dependency1__["default"]; - - /** - `RSVP.Promise.all` accepts an array of promises, and returns a new promise which - is fulfilled with an array of fulfillment values for the passed promises, or - rejected with the reason of the first passed promise to be rejected.
