The collection of functions, keyed by name, available on this ActionHandler as action targets.

These functions will be invoked when a matching {{action}} is triggered from within a template and the application's current route is this route.

Actions can also be invoked from other parts of your application via ActionHandler#send.

The actions hash will inherit action handlers from the actions hash defined on extended parent classes or mixins rather than just replace the entire hash, e.g.:

App.CanDisplayBanner = Ember.Mixin.create({
  actions: {
    displayBanner: function(msg) {
      // ...
    }
  }
});

App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
  actions: {
    playMusic: function() {
      // ...
    }
  }
});

// WelcomeRoute, when active, will be able to respond
// to both actions, since the actions hash is merged rather
// then replaced when extending mixins / parent classes.
this.send('displayBanner');
this.send('playMusic');

Within a Controller, Route, View or Component's action handler, the value of the this context is the Controller, Route, View or Component object:

App.SongRoute = Ember.Route.extend({
  actions: {
    myAction: function() {
      this.controllerFor("song");
      this.transitionTo("other.route");
      ...
    }
  }
});

It is also possible to call this._super() from within an action handler if it overrides a handler defined on a parent class or mixin:

Take for example the following routes:

App.DebugRoute = Ember.Mixin.create({
  actions: {
    debugRouteInformation: function() {
      console.debug("trololo");
    }
  }
});

App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
  actions: {
    debugRouteInformation: function() {
      // also call the debugRouteInformation of mixed in App.DebugRoute
      this._super();

      // show additional annoyance
      window.alert(...);
    }
  }
});

Bubbling

By default, an action will stop bubbling once a handler defined on the actions hash handles it. To continue bubbling the action, you must return true from the handler:

App.Router.map(function() {
  this.resource("album", function() {
    this.route("song");
  });
});

App.AlbumRoute = Ember.Route.extend({
  actions: {
    startPlaying: function() {
    }
  }
});

App.AlbumSongRoute = Ember.Route.extend({
  actions: {
    startPlaying: function() {
      // ...

      if (actionShouldAlsoBeTriggeredOnParentRoute) {
        return true;
      }
    }
  }
});
