好吧,我整天都在研究一个jQuery脚本,大多是调整它以使错误显示正确,并且突然间 - 代码停止工作。表格未提交或任何内容。
下面我已经包含了代码;我假设它在jQuery方面(即谷歌或其他东西),因为我将代码恢复到最后的工作配置,但仍然没有得到任何东西。
编辑:没有控制台错误,jQuery没有提交。这就是我遇到的问题。

答案 0 :(得分:0)
代码存在一些问题,第一件事是在文档准备好后绑定到dom事件。最重要的是,在提交表单时,您需要使用event.preventDefault()
来阻止事件,这会阻止浏览器使用表单的方法执行表单的操作(也就是发布到URL)我已更新代码以反映这些更改也根据您的问题的评论修复了HTML。

<script type='text/javascript'>
// use $(document).ready(function(){})
// $(function(){}) is a shortcut for ready function
$(function(){
$('#login').submit(function(e) {
// stop the form from submitting and allow the ajax to run
e.preventDefault();
$.ajax({
