        }
        //prototype (相同于某个"类"的共享成员表)    用这样定义的方法，他的对象就会共享该方法
        person.prototype.sayHi = function () {
            alert("age=" + this.age + ",name=" + this.name);
        }
        var p1 = new person(12, "刘德华");
        p.sayHi();

        var p2 = new person(21, "习平");
        p2.sayHi();

        //通过call方法模拟new关键字创建对象
        //var p3 = new Object();
        //person.call(p3, 99, "神州");//将对象person方法的this,person 方法为对象添加属性
        //p3.sayHi();
