如何通過價值灰燼的js與控制器進行點擊事件

Question

** ** strong text如何燼

<div> 
{{view "select" content=model prompt="Please select a name" selectionBinding="App.selectedComboBoxController.model" optionValuePath="content.fullName" optionLabelPath="content.title" }} 

    </div> 

    - 
    <p> 
     Selected: {{App.selectedComboBoxController.model.title}} 
</p> 

在上面，我得到正確的輸出碼傳球值控制器。 但我想傳遞一個值控制器無任何按鍵

**Here my controller.** 

App.ComboBoxController = Ember.Controller.extend({ 

}); 

Answer 1

它需要的是將與當前上下文選擇的值時，控制器關聯。所以在下面的例子中，假定當前上下文是索引路由，模型返回一個對象數組。

例如

HBS

<script type="text/x-handlebars" data-template-name="index"> 
    <div> 
    {{view "select" content=model prompt="Please select a name" selectionBinding="controllers.selectedComboBox.model" optionValuePath="content.fullName" optionLabelPath="content.title" }} 
</div> 

    - 

    <p> 
     Selected: {{controllers.selectedComboBox.model.title}} 
</p> 
    </script> 

JS

App.IndexRoute = Ember.Route.extend({ 
    model: function() { 
    return [ 
     {fullName:"the full name1", title:"the title1"}, 
     {fullName:"the full name2", title:"the title2"}, 
     {fullName:"the full name3", title:"the title3"} 
    ]; 
    } 
}); 

App.IndexController = Em.ArrayController.extend({ 
    needs:["selectedComboBox"] 

}); 

App.SelectedComboBoxController = Em.ObjectController.extend({ 
    model:null 
});
