我不是程序员，我只是在努力学习。我将感谢任何帮助。提前感谢

我猜您正在替换页面中按钮所在的部分。（您确实需要更整洁地格式化您的代码，因此……请使用JSFiddle.net及其TidyUp按钮）

如果是这种情况，则需要使用委托事件处理程序：

这将侦听所需节点的静态祖先，然后在事件发生时运行选择器，然后将函数应用于导致事件的任何匹配元素

---

如果您没有方便的祖先，

document

是后备父级。不要将“body”用于委托事件，因为它具有奇怪的行为。

浏览器控制台中是否有错误？假设在点击按钮之间没有页面刷新，那么问题很可能是您试图针对已经初始化的元素（#示例）初始化数据表。如果是这种情况，您将在控制台中看到一个确认错误。如果DataTables已经初始化，正确的方法是使用它们的API更新现有的表，然后通过.draw（）刷新它。谢谢Stevangelista！我一点错误都没有。我想你是对的，似乎是数据表让我头疼。我试过draw（）、drawCallback（）等，但没有成功。我离实现我的想法越来越近了。你为什么要使用jQueryAjax？所以你不必重新初始化。谢谢你的代码建议和TidyUp工具（顺便说一句，非常有用）。但是你的解决方案不起作用。正如Stevangelista所建议的，问题在于DataTables插件。不知何故，我需要将draw（）或drawCallback（）函数绑定到我的按钮上，但到目前为止还没有成功完成。真丢脸。这回答了90%的问题只适用于一次：）请应用TidyUp，因为它是很难阅读的代码，因为它是格式化的。
