The value of this property should be a string representing a path + to another object or a custom binding instanced 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(this.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. + + 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.

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. 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 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 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.

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.

to change what's displayed, simply swap out the + `content` 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 `content` property: + + ```javascript + MyApp.listController = Ember.ArrayController.create(); + + $.get('people.json', function(data) { + MyApp.listController.set('content', data); + }); + ``` + + Then, create a view that binds to your new controller: + + ```handlebars + {{#each MyApp.listController}} + {{firstName}} {{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 `content`, 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}} +

{{title}} ({{titleLength}} characters)

+ {{/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.

+ ``` + + `class` attribute values can also be set by providing a `classNameBindings` + property set to an array of properties names for the view.

+ ``` + + 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 +

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 +

I am the template

+ ``` + + Within an Ember application is more common to define a Handlebars templates as + part of a page: + + ```html + + ``` + + And associate it by name using a view's `templateName` property: + + ```javascript + AView = Ember.View.extend({ + templateName: 'some-template' + }); + ``` + + 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 +

I was the default

+ ``` + + 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 +

I was the template, not default

+ ``` + + ## 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 +

Hello Barry!!!

+ ``` + + 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. ``) + 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("

") + template: Ember.Handlebars.compile("I got wrapped"), + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +

+ I got wrapped +

+ ``` + + 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 + OuterView = Ember.View.extend({ + template: Ember.Handlebars.compile("outer {{#view InnerView}}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 + } + }) + }); + + 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. The names of the built-in events are listed below. (The hash of + built-in events exists in `Ember.EventDispatcher`.) Additional, custom events + can be registered by using `Ember.Application.customEvents`. + + Touch events: + + * `touchStart` + * `touchMove` + * `touchEnd` + * `touchCancel` + + Keyboard events + + * `keyDown` + * `keyUp` + * `keyPress` + + Mouse events + + * `mouseDown` + * `mouseUp` + * `contextMenu` + * `click` + * `doubleClick` + * `mouseMove` + * `focusIn` + * `focusOut` + * `mouseEnter` + * `mouseLeave` + + Form events: + + * `submit` + * `change` + * `focusIn` + * `focusOut` + * `input` + + HTML5 drag and drop events: + + * `dragStart` + * `drag` + * `dragEnter` + * `dragLeave` + * `drop` + * `dragEnd` + + ## Handlebars `{{view}}` Helper + + Other `Ember.View` instances can be included as part of a view's template by + using the `{{view}}` Handlebars helper.

+ ``` + + If an `itemViewClass` is defined on the helper, and therefore the helper is not + being used as a block, an `emptyViewClass` can also be provided optionally. + The `emptyViewClass` will match the behavior of the `{{else}}` condition + described above. That is, the `emptyViewClass` will render if the collection + is empty. + + ### Representing each item with a Controller. + By default the controller lookup within an `{{#each}}` block will be + the controller of the template where the `{{#each}}` was used. If each + item needs to be presented by a custom controller you can provide a + `itemController` option which references a controller by lookup name. + Each item in the loop will be wrapped in an instance of this controller + and the item itself will be set to the `content` property of that controller. + + This is useful in cases where properties of model objects need transformation + or synthesis for display: + + ```javascript + App.DeveloperController = Ember.ObjectController.extend({ + isAvailableForHire: function() { + return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); + }.property('isEmployed', 'isSeekingWork') + }) + ``` + + ```handlebars + {{#each person in developers itemController="developer"}} + {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} + {{/each}} + ``` + + Each itemController will receive a reference to the current controller as + a `parentController` property. + + ### (Experimental) Grouped Each + + When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), + you can inform Handlebars to re-render an entire group of items instead of + re-rendering them one at a time (in the event that they are changed en masse + or an item is added/removed). + + ```handlebars + {{#group}} + {{#each people}} + {{firstName}} {{lastName}} + {{/each}} + {{/group}} + ``` + + This can be faster than the normal way that Handlebars re-renders items + in some cases. + + If for some reason you have a group with more than one `#each`, you can make + one of the collections be updated in normal (non-grouped) fashion by setting + the option `groupedRows=true` (counter-intuitive, I know). + + For example, + + ```handlebars + {{dealershipName}} + + {{#group}} + {{#each dealers}} + {{firstName}} {{lastName}} + {{/each}} + + {{#each car in cars groupedRows=true}} + {{car.make}} {{car.model}} {{car.color}} + {{/each}} + {{/group}} + ``` + Any change to `dealershipName` or the `dealers` collection will cause the + entire group to be re-rendered.

You can extend the + capablilties of checkbox inputs in your applications by reopening this class. For example, + if you wanted to add a css class to all checkboxes in your application: + + ```javascript + Ember.Checkbox.reopen({ + classNames: ['my-app-checkbox'] + }); + ``` + + @method input + @for Ember.Handlebars.helpers + @param {Hash} options +*/ +Ember.Handlebars.registerHelper('input', function(options) { + Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2); + + var hash = options.hash, + types = options.hashTypes, + inputType = hash.type, + onEvent = hash.on; + + delete hash.type; + delete hash.on; + + normalizeHash(hash, types); + + if (inputType === 'checkbox') { + return Ember.Handlebars.helpers.view.call(this, Ember.Checkbox, options); + } else { + if (inputType) { hash.type = inputType; } + hash.onEvent = onEvent || 'enter'; + return Ember.Handlebars.helpers.view.call(this, Ember.TextField, options); + } +}); + +/** + `{{textarea}}` inserts a new instance of ` + ``` + + Bound: + + In the following example, the `writtenWords` property on `App.ApplicationController` + will be updated live as the user types 'Lots of text that IS bound' into + the text area of their browser's window. + + ```javascript + App.ApplicationController = Ember.Controller.extend({ + writtenWords: "Lots of text that IS bound" + }); + ``` + + ```handlebars + {{textarea value=writtenWords}} + ``` + + Would result in the following HTML: + + ```html + + ``` + + If you wanted a one way binding between the text area and a div tag + somewhere else on your screen, you could use `Ember.computed.oneWay`: + + ```javascript + App.ApplicationController = Ember.Controller.extend({ + writtenWords: "Lots of text that IS bound", + outputWrittenWords: Ember.computed.oneWay("writtenWords") + }); + ``` + + ```handlebars + {{textarea value=writtenWords}} + +

+ {{outputWrittenWords}} +

+ ``` + + Would result in the following HTML: + + ```html + + + <-- the following div will be updated in real time as you type --> + +

+ Lots of text that IS bound +

+ ``` + + Finally, this example really shows the power and ease of Ember when two + properties are bound to eachother via `Ember.computed.alias`. Type into + either text area box and they'll both stay in sync. Note that + `Ember.computed.alias` costs more in terms of performance, so only use it when + your really binding in both directions: + + ```javascript + App.ApplicationController = Ember.Controller.extend({ + writtenWords: "Lots of text that IS bound", + twoWayWrittenWords: Ember.computed.alias("writtenWords") + }); + ``` + + ```handlebars + {{textarea value=writtenWords}} + {{textarea value=twoWayWrittenWords}} + ``` + + ```html + + + <-- both updated in real time --> + + + ``` + + ### Extension + + Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing + arguments from the helper to `Ember.TextArea`'s `create` method. You can + extend the capabilities of text areas in your application by reopening this + class. For example, if you are deploying to browsers where the `required` + attribute is used, you can globally add support for the `required` attribute + on all {{textarea}}'s' in your app by reopening `Ember.TextArea` or + `Ember.TextSupport` and adding it to the `attributeBindings` concatenated + property: + + ```javascript + Ember.TextArea.reopen({ + attributeBindings: ['required'] + }); + ``` + + @method textarea + @for Ember.Handlebars.helpers + @param {Hash} options +*/ +Ember.Handlebars.registerHelper('textarea', function(options) { + Ember.assert('You can only pass attributes to the `textarea` helper, not arguments', arguments.length < 2); + + var hash = options.hash, + types = options.hashTypes; + + normalizeHash(hash, types); + return Ember.Handlebars.helpers.view.call(this, Ember.TextArea, options); +}); + +})(); + + + +(function() { +/*globals Handlebars */ +/** +@module ember +@submodule ember-handlebars +*/ + +/** + @private + + Find templates stored in the head tag as script tags and make them available + to `Ember.CoreView` in the global `Ember.TEMPLATES` object.

In this case, no additional parameters will be passed. + + If you provide additional parameters to the helper: + + ```handlebars + + ``` + + 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. + + To also disable bubbling, pass `bubbles=false` to the helper: + + ```handlebars + + ``` + + 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 + + ``` + + See `Ember.View` 'Responding to Browser Events' for a list of + acceptable DOM event names. + + NOTE: Because `{{action}}` depends on Ember's event dispatch system it will + only function if an `Ember.EventDispatcher` instance is available. An + `Ember.EventDispatcher` instance will be created when a new `Ember.Application` + is created. Having an instance of `Ember.Application` will satisfy this + requirement. + + ### 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 + + ``` + + This way the `{{action}}` will fire when clicking with the alt key pressed down. + + ### Specifying a Target + + There are several possible target objects for `{{action}}` helpers: + + In a typical Ember application, where views 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 + + ``` + + Clicking "click me" in the rendered HTML of the above template will trigger + the `anActionName` method of the object at `MyApplication.someObject`. + + If an action's target does not implement a method that matches the supplied + action name an error will be thrown. + + ```handlebars + + ``` + + With the following application code + + ```javascript + AView = Ember.View.extend({ + templateName; 'a-template', + // note: no method 'aMethodNameThatIsMissing' + anActionName: function(event) {} + }); + + aView = AView.create(); + aView.appendTo('body'); + ``` + + Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when + "click me" is clicked. + + ### 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 + + ``` + + Clicking "click me" will trigger the `edit` method on the current view's + controller with the current person as a parameter. + + @method action + @for Ember.Handlebars.helpers + @param {String} actionName + @param {Object} [context]* + @param {Hash} options + */ + EmberHandlebars.registerHelper('action', function(actionName) { + var options = arguments[arguments.length - 1], + contexts = a_slice.call(arguments, 1, -1); + + var hash = options.hash, + controller; + + // create a hash to pass along to registerAction + var action = { + eventName: hash.on || "click" + }; + + action.parameters = { + context: this, + options: options, + params: contexts + }; + + action.view = options.data.view; + + var root, target; + + if (hash.target) { + root = this; + target = hash.target; + } else if (controller = options.data.keywords.controller) { + root = controller; + } + + action.target = { root: root, target: target, options: options }; + action.bubbles = hash.bubbles; + + var actionId = ActionHelper.registerAction(actionName, action, hash.allowedKeys); + return new SafeString('data-ember-action="' + actionId + '"'); + }); + +}); + +})(); + + + +(function() { +/** +@module ember +@submodule ember-routing +*/ + +if (Ember.ENV.EXPERIMENTAL_CONTROL_HELPER) { + var get = Ember.get, set = Ember.set; + + /** + `{{control}}` works like render, except it uses a new controller instance for every call, instead of reusing the singleton controller. + + The control helper is currently under development and is considered experimental. + To enable it, set `ENV.EXPERIMENTAL_CONTROL_HELPER = true` before requiring Ember. + + For example if you had this `author` template. + + ```handlebars +

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 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 + App = Ember.Application.create({ + customEvents: { + // add support for the loadedmetadata media + // player event + 'loadedmetadata': "loadedMetadata" + } + }); + ``` + + 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 + window.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 register additional initializers, like so: + + ```javascript + Ember.Application.initializer({ + name: "store", + + initialize: function(container, application) { + container.register('store:main', application.Store); + } + }); + ``` + + ### 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 + window.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 = Ember.Application = Ember.Namespace.extend(Ember.DeferredMixin, { + + /** + The root DOM element of the Application.
