        logout
    </a>
</script>

您可以使用Ember的needs feature来完成此操作。

您指定控制器“需要”访问另一个控制器，然后Ember允许您在controllers.controllerName访问它：

App.ApplicationController = Ember.Controller.extend({
  applicationAction: function() {
    console.log("action in application controller");
  }
});

App.IndexController = Ember.ArrayController.extend({
  needs: ['application'],
  indexProperty: "index controller"
});

可以在模板中访问：

<a href='#' {{action applicationAction target="controllers.application"}}>
    logout
</a>

JSBin example

在{{action}}帮助程序中调用use alternative controller
