我正在写这篇文章，以获得使用JQuery在玩家之间传递的帮助。我目前正在设计一款有四名玩家的多米诺骨牌游戏。我现在的版本一直工作到最后，但是最后四个版本变得非常迟钝。我已经确定这是由于playTurn函数中的递归。我曾试图使用事件，但这对我来说效果不佳。我的问题是，如果你知道如何使用JQuery创建一个更好的游戏循环。我想使用JQuery完成这个游戏的基础知识，但是对更好的路径的任何建议都将非常感激。代码如下。
P.S。游戏还远没有完成，但我非常希望在继续之前解决这个问题。我也是javascript的初学者。谢谢你的帮助。
编辑：经过一些来自stackover流程用户的修补和帮助，我意识到我的playTurn函数中的addDominoToBoard函数是滞后的主要罪魁祸首。关于如何更好地重绘我的董事会的任何建议。再一次谢谢你。

首先，我要感谢KKetch使我意识到我正在做一堆不必要的DOM操作。在对jQuery进行更多研究后，我意识到声明变量而不是不断获取HTML元素要好得多。但是，这并没有解决我的滞后问题。我通过消除递归和使用事件处理程序解决了我的滞后问题。我的解决方案是依靠隐藏并在屏幕上显示手。我的游戏循环是由用户在网页本身上自我暗示的。对于任何感兴趣的人来说，解决方案如下所示，如果你想跟踪这个项目，这里是github页面的链接。再次感谢。
