当我添加<form>时到我的网页，我所有的 JavaScript 都停止工作，当我将表单放在表格的开头时，提交将无法工作，我做错了什么。下面是我在其他浏览器上测试后的代码，它工作正常，但在 Firefox 上却不行
更新:检查 firefox java 错误控制台后，似乎 Checking函数已定义
更新2:解决了我的错误是<script type="text/jscript">是错误的，这就是为什么它在 Firefox 上不起作用，而在其他设备上却起作用，它一定是 <script type="text/javascript">

最佳答案
您的函数想要接收表单元素，而您的提交按钮不会向该函数发送任何内容。我假设它没有提交，因为你的函数出错了，因此停止了按钮，就像它返回 false 一样。修复您的 JavaScript，尝试使用 Firebug 来帮助您发现这些问题。
