javascript 面向对象实例

直接上源码吧：

(function()
  {
    var ntx=function()
    {
      return this;
    }
     ntx.prototype={
       id:"test",
      aa:function(bb)
      {
        alert(bb);
      },
      cc:function(dd)
      {
       alert(dd);
      }
    }
    window.test = ntx;
   })();
</script>
</head>

<body>
<script>
(function(){
    var xt = new test();
    xt.aa("xx and xx");
    xt.cc("这是一个测试！");
    xt.cc(xt.id);
  })();
</script>
</body>
</html>

注意：最后xt是new出来的且要将ntx保存到window变量中
