JS方法内变量定义访问

<script type="text/javascript">
   function test(){
       var obj = this;
       obj.pub1 = ‘pub1‘;  //公有变量

       var pri1 = ‘pri1‘;  //私有变量（类内部访问相当于private修饰）
       this.getPri1 = function(){  //实现一个访问器使外部能访问到是有变量
       	   return pri1;
       }

   }
   var service = new test();
   console.log(service.pub1);  // pub1
   console.log(service.pri1);  // undefined(无法访问到私有变量)
   console.log(service.getPri1());  //pri1
</script>
