有人看到下面的问题吗？我试图让 ajaxSubmit() 工作，但第一步失败了。我的理解是，任何动作脚本（此处为 processaj.php）输出都应放入#output 元素中。我已将 processaj.php 简化为：

<?php
    error_reporting(E_ALL);
    echo ("In processaj.php");
?>

因此，当我提交某些内容时，我期望“在 processaj.php 中”会出现在#output div 中，但什么也没有出现。谢谢你的帮助..

Instead of using e.PreventDefault(), you should return false in the on submit callback function. As stated in the documentation.

$('#myForm2').submit(function() { 
    // inside event callbacks 'this' is the DOM element so we first 
    // wrap it in a jQuery object and then invoke ajaxSubmit 
    $(this).ajaxSubmit(options); 

    // !!! Important !!! 
    // always return false to prevent standard browser submit and page navigation 
    return false; 
});
