width: 500,

Thanks for your answers. The problem was that the library was included multiple times in different files.
感谢您的回答。问题是该库多次包含在不同的文件中。

View the page's HTML to see if there are script references to other versions of jquery in the page. If an older version is loaded after the correct version then invalid methods will throw exceptions.
查看页面的 HTML 以查看页面中是否存在对其他版本的 jquery 的脚本引用。如果在正确版本之后加载旧版本,则无效方法将引发异常。

The dialog method is from the jQuery UI library. It looks like you are using a custom version of jQuery UI, which maynot include dialog.
dialog 方法来自jQuery UI 库。看起来您正在使用自定义版本的 jQuery UI,其中可能不包括对话框。
You can customize which modules to include in jQuery UI here: http://jqueryui.com/download
您可以在此处自定义要包含在 jQuery UI 中的模块:http: //jqueryui.com/download
