Javascript 余烬js中更改侦听器的组合框

我使用下面的代码在余烬中显示组合框

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

输出

我的要求是组合框更改时间如何调用下面的提交功能

App.ComboBoxRoute = Ember.Route.extend({

    model: function () {     
          return posts;     
    },
    actions: {
        submit: function () {
           textId = document.getElementById("emnn");
           textId = textId.value;
            alert(textId);
        }
    }

});

您可以向组合框值添加观察者。在“观察者”中，发送一个动作，该动作将使路线冒泡

App.SelectedComboBoxController = Em.ObjectController.extend({
  model:null,

  selectionChanged: function() {
    this.send('submit', this.get('model'));
  }.observes('model')
});

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"}
    ];
  },
  actions: {
    submit: function (item) {
      alert(item.fullName);
    }
  }
});
