this seems to be almost a duplicate of <a href="https://stackoverflow.com/questions/8596861/super-in-backbone">Super in Backbone</a>, so you want something like this:

<pre><code>Backbone.Model.prototype.initialize.call(this);

blocks|key|456395|text|类似于@wheresrhys，但如果BaseModel.initialize需要参数，我会使用apply而不是call。我尽量避免处理可以在初始化时传递给Backbone+Model的属性映射，但是如果BaseModel实际上是一个视图或集合，那么我可能想要设置选项。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|456396|var+MyModel+=+BaseModel.extend({

Similar to @wheresrhys, but I would use apply instead of call in case BaseModel.initialize is expecting arguments. I try to avoid processing the attributes map that can be passed to a Backbone Model upon initialization, but if the BaseModel were actually a View or a Collection then I might want to set options.

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

here's a multi generation callSuper method, just add it to your extending class.

<pre><code>callSuper: function (methodName) {
 var previousSuperPrototype, fn, ret;

 if (this.currentSuperPrototype) {
 previousSuperPrototype = this.currentSuperPrototype;
 // Up we go
 this.currentSuperPrototype = this.currentSuperPrototype.constructor.__super__;
 } else {
 // First level, just to to the parent
 this.currentSuperPrototype = this.constructor.__super__;
 previousSuperPrototype = null;
 }

 fn = this.currentSuperPrototype[methodName];

 ret = (arguments.length &gt; 1) ? fn.apply(this, Array.prototype.slice.call(arguments, 1)) : fn.call(this);

 this.currentSuperPrototype = previousSuperPrototype;

 return ret;

You might consider rewriting your code using functional inheritance.

<pre><code>var BackBone=function(){
 var that={};

 that.m1=function(){

 };
 return that;

};

var MyModel=function(){

 var that=BackBone();
 var original_m1=that.m1;

//overriding of m1
 that.m1=function(){
 //call original m1
 original_m1();
 //custom code for m1
 };
};
</code></pre>

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

How could I do this?

Here's what my code looks right now:

<pre><code>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.
 },
});
</code></pre>

Accessing parent class in Backbone

我需要从继承的MyModel-class内部调用父类的initialize方法，而不是像今天那样完全覆盖它。我怎么能这样做呢？下面是我的代码现在的样子：BaseModel = Backbone.Model.extend({    initialize: function(attributes, options) {        // Do parent stuff stuff    }});My
