Question

我正在努力追踪篮球比赛的时间。

我需要的是

倒数计时器，暂停并继续。为此，我使用在的代码 http://jchavannes.com/jquery-timer/demo
我还需要跟踪每位玩家参加游戏的时间。并非所有玩家都同时参与游戏。
我想解决的问题。 1）能够从任何时间动态启动倒数计时器。我的意思是当页面开始时，每次的时间可能不同。 2）能够在计时器停止时向计时器添加或减少分钟或秒。 3）能够计算游戏中玩家的时间。也就是说当他们被替换时，他们的计算时间应该暂停并开始计算进入游戏的玩家的时间。 4）正如你所看到的，我创造了一个 var CustomPlayer1 = new（function（）{...} var CustomPlayer2 = new（function（）{...} 我知道为所有球员创造所有这一切并不是最好的（两支球队可能24人）。如何更有效地创造这个？

从一开始。你可能需要的任何其他东西，以及可能帮助我做到这一点，我很乐意告诉你。

到目前为止我所拥有的是以下内容。（它远远不是我所需要的）
