Question

如何在ArrayController.content []属性中的数组中显示特定项？我有以下代码：

App.View.PairView = Em.View.create({    
  templateName: 'display-template',
  controller: App.Controller.PairController 
});


App.Controller.PairController = Em.ArrayController.create({
  content: [],
  createNew: function(){        
    var weeks = ['1','2','3'];
    var quarters = ['Q1', 'Q2', 'Q3'];
    var months = ['Jan', 'Sep', 'Dec'];

    this.set('content', []);
    this.pushObject(weeks);
    this.pushObject(quarters);
    this.pushObject(months);        
  }
});

我只想获得App.Controller.PairController.content [0] [0]或“周”。如果我有下面的把手模板，我怎么写呢？

<script type="text/x-handlebars" data-template-name="display-template">
  {{#each item in controller}}                                                  
       ???????????????????????
   {{/each}}      
</script>

谢谢。
