Question

我在ASP.NET MVC5中基本使用JQuery UI库时遇到了困难。虽然我使用它的自动完成没有问题，但每当我尝试使用对话框时，我在.dialog行上得到一个'undefined is a function'错误。鉴于我正在使用自动完成，它会建议加载UI脚本。

为了进一步检查，我已将它全部剥离，因此它只是基本MVC模板的索引页面上的对话框，其中包含最简单的所有更改 - 对于html，对话框的div和要打开的按钮它，以及脚本，以正确的顺序链接到外部库 - JQuery然后JQuery UI（同时取出了jquery捆绑）。下面是生成页面的页面源，它仍然生成相同的错误。

知道我做错了什么？

提前致谢，
