页面模板中的操作交互按钮，默认指向该模板对应的控制器。当然也可以指向相对应的路由和视图，只需要在这些类里面定义该操作处理函数即可，例如

{
    {#if isExpanded}}  
    
     { { body}}
    
 Contract { { else}} Show More... { {/if}}

App.PostController = Ember.ObjectController.extend({  // initial value  isExpanded: false,  actions: {    expand: function() { this.set('isExpanded', true); }, contract: function() { this.set('isExpanded', false); } } });

App.PostRoute = Ember.Route.extend({  actions: {    expand: function() {      this.controller.set('isExpanded', true); }, contract: function() { this.controller.set('isExpanded', false); } } });

App.PostsIndexView = Ember.View.extend({  actions: {    select: function(post) {      // do your business.    }  }});
