js反射机制

反射机制：是指程序在运行时能够获取自身的信息

eg:一个对象在运行时，知道自己的属性和方法

var obj={

name:"zhangkaibo",

age = 25,

talk:function(){alert("my name is zhangkaibo")}

}

var obj1 = function(){

  this.name:"zhangkaibo";

 var age = 25;

this.talk=function(){alert("my name is zhangkaibo")}

}

function Reflector(obj){

for(var p in obj){

  if(typeof(obj[p]) == "function"){

 obj[p]();

}else{

alert[p]

}

}

}
