    var Teacher = {
        name = "mingzi",
        age = 18,
        showName:function()
        return this.name;
    }
    Teacher.showName();
  2. 原型模式属性放在构造函数里，方法放在原型上

    function Teacher(name,age){

    }
    Teacher.prototype.showName = function(){
        return this.name;
    }

    var mingzi = new Teacher("小明",18);
    mingzi.showName();

    var mingzi = new Teacher("小明",age);
    mingzi.showName;
