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 = []; }
