JS中的public和private对象,即static修饰符

//重新封装document对象
varConsole={
Write:function(msg){alert(msg);}
};
//Person对象
varPerson={
_name:"zzl",//staticpublic
_age:28,
PrintInfo:function(){Console.Write("name:"+Person._name+",age:"+this._age);}//publicmethod,this表示Person
};

//People类型(对象)
varPeople=(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
