JS 和 Bootstrap 在 Codepen 中工作，但在本地打开时不工作

Question

这是我的代码笔： https://codepen.io/ldrumsl/pen/ZxdZwa

这是JS：

$('#datetimepicker1').datetimepicker();
$('#datetimepicker2').datetimepicker();

这是下载的 index.html 文件：

</html>

上面的link如我所愿。但是，当我导出文件并在本地打开它时，我得到如下内容：

Image of local code

有谁知道如何获取它以便我的代码在本地运行？我直接从 codepen 导出了文件，没有做任何更改。

Answer 1

在本地更改这些行 html :

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">

<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

https: 在样式表 url 中被遗忘。
