在Ember.Select中绑定操作 [英] Binding Action in Ember.Select

问题描述

我想知道如何在Ember.Selectsó中绑定一个动作，当用户更改类别时，我可以执行其他操作：

  {{查看Ember.Select class =form-controlid =PackCategory
 content = Categories 
 optionValuePath =content.categoryId
 optionLabelPath =content.name 
 value = VendingAdminController.selectedPack.categoryId}} 
  

以及如何将视图指定为目标？

谢谢

解决方案

/ p>

只需在控制器中创建一个观察 {{select}}的价值属性的函数

  onSelectedPackChange：function（）{
 //插入需要排除的代码在这里更改
} .observes （'selectedPack.categoryId'）
  

上面的代码应该放在你的 VendingAdm inController 。

I was wondering how to bind an action in an Ember.Select só when the user change the category i could perform other operations:

{{view Ember.Select class="form-control" id="PackCategory"
            content=Categories
            optionValuePath="content.categoryId"
            optionLabelPath="content.name"
            value=VendingAdminController.selectedPack.categoryId}}

and also how to specify the view as the target?

Thank you

Like kingpin suggested,

Just create a function in your controller that observes the value property of the {{select}}

onSelectedPackChange:function(){
  //insert the code that needs to be excuted on change here
}.observes('selectedPack.categoryId')

The above code should be placed in your VendingAdminController.
