js 遍历对象的属性的代码

Function.prototype.addMethod=function(methodName,func){ 
if(!this.prototype[methodName]){ 
this.prototype[methodName]=func;//给原型增加方法，此方法会影响到该类型的实例上 
} 
return this.prototype;//返回原型，此类型实例可以进行链形调用 
} 
function CustomObject(name,value){ 
this.name=name || 'CustomeObject'; 
this.value=value || 0; 
this.toString=function(){ 
return '[name:'+this.name+',value:'+this.value+']' 
} 
} 
CustomObject.addMethod('testFun',function(){}) 
var obj=new CustomObject(); 
var info=''; 
for(var property in obj){ 
info+=property+" | "; 
} 
alert(info); // name | value | toString | testFun |
