JS 仿java的get set访问器，私有成员， 伪事件

没有什么难度，主要加深对JavaScript的理解 


var Student = function (name, no) {
    var name = name; //相当于私有属性
    var no = no;

    this.setName = function (value) {
        name = value;
        for (var i = 0; i < this.nameModifyListeners.length; i++) {
            this.nameModifyListeners[i](this);
        }
    }

    this.getName = function () {
        return name;
    }

    this.setNo = function (value) {
        no = value;
    }

    this.getNo = function () {
        return no;
    }

    this.sayInfo = function () {
        alert(name + "," + no);
    };

    /**
    * function(Student)
    */
    this.nameModifyListeners = [];

}
