A link to the Plunker. 我现在已经在jQuery中使用按钮和列表系统了一段时间。最近我决定使我的代码更具可重复性。我想这样做，所以我只需要添加类或ID，而且我不必添加任何其他代码。我非常接近为我的整个网站做这件事。因此，如果你专门去this site，你会看到它在行动。
如果您按任何顺序点击任何按钮，它将按时间顺序排列。 这些错误来自关闭它们。 如果你点击至少三个，关闭中间一个，然后单击一个新按钮，排序功能崩溃，关闭中间的一个现在浮动错误的类。 下面是我目前的jQuery。在我的网站上，忽略＆＃34;所有年份＆＃34;按钮。在我弄清楚这个错误之后，我将继续努力。

如果您想参考以前的工作原理，我可以发布该代码。它更笨重，更有组织。我已经尝试了许多不同的东西来消除这个错误，但我不知所措。我对JS范围的了解有限。 感谢任何帮助，非常感谢。
