我的sample code: 最后是framework debug

<html>  <script>    function Aggregation(name) {  this.mAggregationName = name;  }    var oItemAgg = new Aggregation("item"); // so far, Aggregation oject has no available method    debugger;    Aggregation.prototype.generate = function(add, prototype) {  var that = this, n = that.mAggregationName;    add("getAggregation", prototype, function() {  console.log(" getAggregation should be implemented here!");  });  }    function add(name, proto, fn){  if ( !proto[name] ) {  proto[name] =  fn;  }  }    oItemAgg.generate(add, Aggregation.prototype);    oItemAgg.getAggregation();    debugger;  </script>

这里的bindItem实际上不是一个function,而是Javascript对象的一个attribute,该attribute指向了一个匿名函数,其实现是 this.bindAggregation(n, o, t, s,f)
