我有一个HTML表格，我希望能够在单击按钮后添加一行，并弹出一个对话框，我可以在其中输入必要的行信息。我遇到了一些完全符合我想要的代码。我根据我的代码量身定制了它。到目前为止，我有弹出框，但是在点击＆＃34;添加行＆＃34;之后它没有添加一行。在弹出窗口，这是我需要它做的。我希望有人可以告诉我这有什么问题。我非常坚持它。

我知道现在验证已经关闭，但这不是我目前关注的焦点。我只想在填充弹出窗口后添加一行。

我将您的代码放在this fiddle中，删除了PHP部分，以便更好地调试它。我不确定你知道的一件事，虽然它非常有用，但你可以使用浏览器的控制台（右键单击＆gt; Inspect＆gt;控制台）来查找最终的JS错误。
无论如何，点击Add Row时没有发生任何事情，因为您的脚本中存在一些错误。
1）这一行：mr_name = $( "#mr_name" ),应为mr_name = $( "#mr_id" ),，因为mr_id是您为HTML输入提供的id
2）这一行：valid = valid && checkRegexp( mr_id, /^[a-z]([0-9a-z_\s])+$/i, "Username may consist of a-z, 0-9, underscores, spaces and must begin with a letter." );应该有mr_name而不是mr_id，因为它是您在上一项中提到的行中命名的变量
