JS中的public和private对象,即static修饰符

//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
