如何解决为什么我得到 Uncaught TypeError: $(...).DataTable is not a function
我开始使用 DataTable.js，当我想集成到我在 ASP.NET CORE MVC 5.0 中完成的项目时，我收到了类似的错误
Uncaught TypeError: $(...).DataTable is not a function
我尝试谷歌，我发现当你的 JQuery 是旧版本时可能会出现这个错误，但我更新到最新版本 3.7.1
<script
src="https://code.jquery.com/jquery-3.5.1.js"
integrity="sha256-QWo7LDvxbWT2tbbQ97B53yJnYU3WhH/C8ycbRAkjPDc="
crossorigin="anonymous"></script>
我还看什么，我尝试将函数调用更改为按 ID 和按类调用，但也没有任何变化。
这是我的布局页面，其中包含 datatable.min.js 和 datatable.js

有谁知道我哪里出错了？这里有什么问题？
解决方法
当您加载 jQuery 时，您会创建一个 $ 和 jQuery 的新实例，它们没有任何插件您之前已加载并且附加到以前的 jQuery 实例。
<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0="
crossorigin="anonymous"></script>
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/jquery/dist/jquery.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
您正在加载四种不同版本的 jQuery！
加载一个并确保它是当前版本。
删除上面引用的所有行，除了第一行。
您正试图在加载在文档正文中的脚本中调用 DataTables，该脚本位于您所在的页脚上方：
<script type="text/javascript" src="~/datatables/datatables.min.js"></script>
<script type="text/javascript" src="~/datatables/datatables.js"></script>
您需要在调用它之前加载插件。
您也不应该两次加载插件。
移动其中一行，使其紧跟在您加载 jQuery 的行之后。删除另一个。
