您可以将观察者添加到组合框值。在观察者中发送一个会使路线起泡的动作。

Here is the working demo.

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);
    }
  }
});
