Question

我似乎无法在下拉菜单的href部分加载我的任何文件。我正在尝试在.where-you-tune类中动态加载文件。我不知道自己做错了什么，因为我一直在

（index）：81 Uncaught TypeError：$（...）。load不是函数

我已经排除了一些引导代码，因为没有必要

Answer 1

您展示的代码包含2个版本的jQuery。它们是冲突的，导致你的jQuery根本无法工作。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

jQuery slim发布是一个替代，不是以及主发行版。

删除其中一个，您的代码运行正常 - 我已在本地验证了这一点。

将html文件从href加载到div中不会使用jquery .load
