Question

无论我怎么做，我都无法摆脱这个错误。我试图制作一些可拖动的div但我得到错误'参考错误：$未定义'。我查看了我的代码，一切正常。所以我测试了运行jQuerys examplecode for draggable divs，仍然是同样的错误。这是代码。

    <!DOCTYPE html>
    <html lang="en">
       <head>
       <meta charset="utf-8">
       <title>jQuery UI Draggable - Default functionality</title>
       <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
       <script src="//code.jquery.com/jquery-1.10.2.js"></script>
       <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
   <style>
   #draggable { width: 150px; height: 150px; padding: 0.5em; }
   </style>
   <script>
   $(function() {
    $( "#draggable" ).draggable();
   });
   </script>
   </head>
    <body>

<div id="draggable" class="ui-widget-content">
  <p>Drag me around</p>
</div>


</body>
</html>

这是我自己的代码：

将jquery链接替换为此链接并且您正在： https://code.jquery.com/jquery-2.2.0.min.js

即

<script type="text/javascript" src="https://code.jquery.com/jquery-2.2.0.min.js"></script>

无论如何 - 未定义引用错误$（jQuery UI）
