为什么我仍然收到 "jQuery is not defined" 错误
Why am I still getting "jQuery is not defined" error
我是 jQuery 和 Visual Studio 环境的新手。我正在使用 this link 上的指南创建一个圆形导航菜单栏
主要问题出在我提到所有 jQuery 和 jQueryUI 脚本的 head 部分。这是错误的屏幕截图。所有其他Whosebug问题都无法解决这个问题。
代码如下。请帮忙!
提前致谢。

试试另一个版本的 jquery
下载 min.js 个文件并将其放在本地目录中,并在 src 中提供有效路径。
它可能对你有帮助。
http://jquery.com/download/
使用绝对或相对路径,例如。 '/js/jquery.js' 使用 webroot 或 '../js/jquery.js' 取决于你从哪里调用文件(使用绝对路径更好)。尽量不要使用 ~
指标。
而不是这个:
<script src="~/Scripts/jquery-1.11.2.js"></script>
使用:
<script src="/Scripts/jquery-1.11.2.js"></script>
取决于文件相对于 webroot 的位置。
您的 jquery 文件可能有问题。
尝试使用 google 的在线版本。

我不知道问题出在哪里,但我创建了一个新项目并一个一个地添加了所有 .js 脚本并且成功了。
