“0x800a1391 – JavaScript运行时错误：’jQuery’未定义”错误

请关注背景故事，因为它可能与问题有关：

因此，我正在尝试学习ASP.NET MVC 5，并且我从没有任何东西开始学习，并慢慢积累起来。 我能够找到的最好的教程是用于设置记录存储的MVC 3 ASP.NET教程。 所以我删除了基本的MVC 5的所有内容，以便将页面返回给我，然后开始学习本教程。 在我获得第7部分的会员资格和授权之前，我只能解决几个小问题。 添加列出的控制器，模型和视图并遵循使用ASP.NET Web应用程序管理页面所需的步骤后，每次尝试转到LogOn页面时，我都会收到上述错误消息。 我已经完成了我能想到的一切，找到了我可能缺少参考的地方，但却找不到一个。 我甚至通过确保我在原始教程文件中找到的所有引用都复制到我拥有的文件中并且没有帮助。 我终于在Visual Studio 2010中打开了原始版本并且它给出了同样的错误，所以我不知道问题可能在哪里。

每次尝试进入LogOn页面时，我都会收到上述错误消息

如果我没有弄错你的LogOn页面根本没有jquery …并且重复调用jquery.validate插件…. 

   .... //then again here: @Scripts.Render("~/bundles/jqueryval")

所以试试吧： 

 @Scripts.Render("~/bundles/jquery", "~/bundles/jqueryval")

心连心…
