覆盖时调用Mixin方法

本文介绍了覆盖时调用Mixin方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的控制器中有一个Mixin，它有特定的动作。我需要重写此操作，执行一些操作，然后调用Mixin提供的原始操作。

I've got a Mixin in my controller that has a particular action. I need to override this action, do some stuff, and then call the original action provided by the Mixin.

我该怎么做？

this._super（）在这种情况下似乎不起作用（这确实是有道理的，因为这意味着调用超类的实现，而不是Mixin。）

this._super() doesn't seem to work in this case (which does make sense, as it's meant to call the superclass' implementation, not a Mixin's).

推荐答案

为了调用 this._super 从 Ember.run.next 中尝试以下操作，

In order to call this._super from Ember.run.next try the following,

emberjs.jsbin/docig/3/edit

App.MyCustomMixin = Ember.Mixin.create({ testFunc:function(){ alert('original mixin testFunc'); }, actions:{ testAction:function(){ alert('original mixin testAction'); } } }); App.IndexController = Ember.Controller.extend(App.MyCustomMixin,{ testFunc:function(){ alert('overriden mixin testFunc'); var orig_func = this._super; Ember.run.next(function(){ orig_func(); }); }, actions:{ test:function(){ this.testFunc(); }, testAction:function(){ alert('overriden mixin testAction'); var orig_func = this._super; Ember.run.next(function(){ orig_func(); }); } } });
