关于在IIS 7 localhost中托管网站时加载css和Js的问题

Question

这是我的登录主页面代码，很少有Js文件和css文件我无法使用CDN和加载登录页面时抛出错误说明：'$'is undefined

<link rel="stylesheet" href="Assets/css/style.css" type="text/css" />
     <script src="../Assets/lib/jquery/jquery.min.js" type="text/javascript"></script>
    <script src="../Assets/lib/perfect-scrollbar/js/perfect-scrollbar.jquery.min.js" type="text/javascript"></script>
    <script src="../Assets/js/main.js" type="text/javascript"></script>
    <script src="../Assets/lib/bootstrap/dist/js/bootstrap.min.js" type="text/javascript"></script>
    <script src="../Assets/js/Portal.js" type="text/javascript"></script>
    <script src="../Assets/js/BootstrapValidator.js"></script>
    <script>

        $(document).ready(function () {
            //initialize the javascript
            App.init();
        });

    </script>

我的文件路径是Project / Assets文件夹

我尝试过的事情：

<location path="js">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
    </system.web>
  </location>

在请求过滤中添加了文件扩展名.js和.css，并允许为True.Kindly帮助
