（index）：1拒绝应用“https://databasetable-net.000webhostapp.com/media/css/site-examples.css?_=19472395a2969da78c8a4c707e72123a”中的样式，因为其MIME类型（“text / html”）不是受支持的样式表MIME类型，并且启用了严格的MIME检查。

代码： 具有讽刺意味的是，Codepen上的相同代码没有错误。

可能是解决方案：我尝试了很多，但这里有一些：

添加数据类型：json（但我没有使用Ajax，但我还是尝试在Jquery下使用它而没有效果）

添加标题总是设置X-Content-Type-Options nosniff
（不完全确定在哪里放这个，但尝试了很多地方，似乎没有工作）

从text / javascript更改了应用程序/ javascript（但什么都没做）

我还无法发表评论，因此我被告知要根据我的问题制作一个新主题具有讽刺意味的是，相同的代码适用于CodePen。

Answer 1

标题中有一行会导致错误。

这一行：

 <style type="text/css" class="init"> </style>

无效。删除type="text/.css"部分

编辑

在编辑中粘贴网站的网址后，我能够访问该网站并识别错误。

您还必须将以下文件上传到您的网站：

无法加载资源：服务器响应状态为404（）

demo.js
站点examples.css
dynamic.php
demo.js

看起来您还缺少Datatables JS脚本的关键元素。

    (index):22 js ready
    (index):24 Jquery ready
    jquery.dataTables.min.js:23 Uncaught TypeError: Cannot read property 'length' of undefined

修改

您必须指定上述javascript / css文件的完整网址
