我得到了mootools的倒计时here，但它看起来像没有工作
我得到了36（this.timer = new PeriodicalExecuter(this.update.bind(this), (this.options.frequency || 1000)/1000);）Mootools的计数器倒计时不行
类PeriodicalExecuter似乎未列入mootools的在CountDown.js线一条错误消息Uncaught ReferenceError: PeriodicalExecuter is not defined 。希望有人拥有PeriodicalExecuter的代码或知道我在哪里可以找到它。
类PeriodicalExecuter应至少包括功能stop()和registerCallback()
这里是CountDown.js的代码，供大家参考

我使用MooTools的1.4.5版本与兼容性
