        <ol>
            <li><div>Some sub-item content</div></li>
            <li><div>Some sub-item content</div></li>

我测试了nestedSortable，这段代码工作

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
  <title><?php echo $meta_title; ?></title>

  <!-- <link href="css/bootstrap.min.css" rel="stylesheet"> -->
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" />
  <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->

  <script src="http://mjsarfatti.com/sandbox/nestedSortable/jquery.mjs.nestedSortable.js"></script> 


      <script>
        $(document).ready(function(){
          $('.sortable').nestedSortable({
            handle: 'div',
            items: 'li',
            toleranceElement: '> div'
          });
        });
      </script>
    </head>

    <body>

      <div>
        <ol class="sortable">
          <li><div>Some content</div></li>
          <li>
            <div>Some content</div>
            <ol>
              <li><div>Some sub-item content</div></li>
              <li><div>Some sub-item content</div></li>
            </ol>
          </li>
          <li><div>Some content</div></li>
        </ol>

      </div>
    </body>

尝试将此代码放在一个文件中并执行它。如果有效，请不要使用外部链接

下载css和js将它们保存在项目文件夹中并从那里包含它们

Answer 2

您必须使用 nestedSortable 的升级版本。以下是nestedSortable的更新版本：https://github.com/ilikenwf/nestedSortable

您还没有在文件中包含jquery-ui.js文件：<script src="//code.jquery.com/ui/1.10.4/jquery-ui.min.js"></script>在包含jquery.mjs.nestedSortable.js文件之前添加此代码

Answer 3

错误表明jQuery对象上不存在该方法。这意味着nestedSortable插件尚未加载。

请参阅此行：

<script src="js/jquery.mjs.nestedSortable.js"></script>

检查地址是否正确，以及该位置是否存在JavaScript文件。

Answer 4

更新您的脚本

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
  <script src="http://mjsarfatti.com/sandbox/nestedSortable/jquery.mjs.nestedSortable.js"></script>

要

<script src="js/jquery-ui.js"></script>
<script src="js/jquery.mjs.nestedSortable.js"></script>

Answer 5

在以下github上：NESTEDSORTABLE

未捕获的TypeError：$（...）。nestedSortable不是函数
