JQuery UI Undefined is not a Function error with Dialog Box答案

【问题描述】：

我在基本使用 ASP.NET MVC5 中的 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，我都会在 .dialog 行上收到“未定义不是函数”错误。鉴于我正在使用自动完成功能，它会建议加载 UI 脚本。

为了进一步检查，我将其全部剥离，因此它只是基本 MVC 模板的索引页面上的对话框，其中最简单的更改是 html、对话框的 div 和打开按钮它，对于脚本，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）。下面是生成的页面的页面源，它仍然会产生相同的错误。

知道我做错了什么吗？

提前致谢，

罗伯特
