//定义类
function StudentObject(){

    this.Name = "";
    this.Age = "";
    this.Sex = "";
    this.Grade = "";
    this.Address = "";
    this.Phone = "";

    //Method

}
//类的方法实现
function ff(){return "my name is " + this.Name;}

//测试
var stobj = new StudentObject();
stobj.Name = "Henry";
alert(stobj.tt());
