在 Backbone 中访问父类

本文介绍了在 Backbone 中访问父类的处理方法，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

我需要从继承的 MyModel 类内部调用父类的 initialize 方法，而不是像我今天所做的那样完全覆盖它.>

我怎么能这样做?

这是我的代码现在的样子:

BaseModel = Backbone.Model.extend({初始化:函数(属性，选项){//做父级的东西}});MyModel = BaseModel.extend({初始化:函数(){//调用 BaseModel.initialize();//继续为这个子类做特定的事情.},});

解决方案

MyModel = BaseModel.extend({初始化:函数(){MyModel.__super__.initialize.apply(this, arguments);//继续为这个子类做特定的事情.},});

I need to call the initialize method of the parent class, from inside the inherited MyModel-class, instead of completely overwriting it as I am doing today.

How could I do this?

Here's what my code looks right now:

BaseModel = Backbone.Model.extend({
    initialize: function(attributes, options) {
        // Do parent stuff stuff
    }
});

MyModel = BaseModel.extend({
    initialize: function() {
        // Invoke BaseModel.initialize();
        // Continue doing specific stuff for this child-class.
    },
});

解决方案

MyModel = BaseModel.extend({
    initialize: function() {
        MyModel.__super__.initialize.apply(this, arguments);
        // Continue doing specific stuff for this child-class.
    },
});
