Jquery Modal/Dialog表单不起作用

Jquery Modal/Dialog form not working

本文关键字：表单 不起作用 Dialog Modal Jquery      更新时间：2023-09-26

嗨，我刚开始编码&尝试使用Jquery库Dialog/Modal表单。我已经准备好了所有的CSS、JS和HTML，但当我点击"创建新用户"时，对话框/Modal不会出现（按钮后面的功能不起作用）。我在控制台中得到了以下错误-任何帮助都将不胜感激：

控制台中的错误消息：

Uncaught TypeError: undefined is not a function    main.js
and it points to this ---> dialog = $( "#dialog-form" ).dialog({

请确保您拥有jquery ui和与该ui配套的css。您的代码很好，只需将其添加到<head>:中即可

<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/themes/smoothness/jquery-ui.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js"></script>

请参阅工作演示：http://jsfiddle.net/swm53ran/221/

看起来您导入了jquery而不是jquery ui。试着导入jqueryui，你应该会没事的。

在你的头上加上这行：

<script src="//code.jquery.com/ui/1.11.2/jquery-ui.js"></script>

也添加这个css：

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.2/themes/smoothness/jquery-ui.css">
