显示表单但没有任何验证工作，弹出窗口也没有出现！

Answer 1

我没有在你的代码中的任何地方看到jquery-ui js / css文件。你必须包含它们才能使jquery-ui小部件工作。

请阅读 http://learn.jquery.com/jquery-ui/getting-started

Answer 3

当我点击创建新用户时，我会在chrome中弹出一个带有验证功能的弹出窗口。您可能有浏览器兼容性问题。您使用哪种浏览器？

Answer 4

始终明智地确保在$( "#dialog-form" ).dialog({

中创建$(function() {

Jquery模式对话框窗体不显示为弹出窗口
