Backbone 扩展视图，扩展方法

Question

我如何扩展扩展视图父方法而不覆盖，保留父方法语句并添加一些自定义代码，这里是示例

var SomeView = View.extend({
  parentMethod: function() {
    //some parent code
  }
})


var MyView = SomeView.extend({
  parentMethod: function() {
     //keep parents statements and extend
  }
})

JavaScript does not provide a simple way to call super — the function of the same name defined higher on the prototype chain. If you override a core function like set, or save, and you want to invoke the parent object's implementation, you'll have to explicitly call it

http://backbonejs.org/#Model-extend

   var MyView = SomeView.extend({
      parentMethod: function() {
         SomeView.prototype.parentMethod.apply(this, arguments);
         //some additional logic
      }
    })
