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 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.

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.

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.

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 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.

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.

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.
