先看下面的例子,它将告诉我们在JS世界中也有C#里的public , private ,及static等

//重新封装document对象

var Console={

Write:function(msg){alert(msg);}

};

//Person对象

var Person={

_name:"zzl", //static public

_age:28,

PrintInfo:function(){Console.Write("name:"+Person._name+",age:"+this._age);} //public method ,this表示Person

};

// People类型(对象)

var People=(function()

{

var _name="zzl";//private

var _age=28;

return {//public

PrintInfo:function(){Console.Write("name:"+_name+",age:"+_age);}

}

}

());

Person.PrintInfo();//对象中的方法

People.PrintInfo();//方法对象中的公开子方法

Console.Write(Person._name);//对象中的属性
