为什么Telerik cdn在IE中不起作用

这是一个非常愚蠢和业余的问题，但我在演示网站中使用了Telerik的CDN，它在除IE之外的任何地方都有效，我想知道为什么会发生这种事。

我包括了所有像这样的文件

<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.1.412/styles/kendo.common-material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.1.412/styles/kendo.material.min.css" />
<link rel="stylesheet" href="http://kendo.cdn.telerik.com/2016.1.412/styles/kendo.mobile.all.min.css" />    
<script src="//kendo.cdn.telerik.com/2016.1.412/js/jquery.min.js"></script>
<script src="//kendo.cdn.telerik.com/2016.1.412/js/kendo.all.min.js"></script>

正如你所看到的，我试着像他们在dojo示例中所做的那样做，我也试着添加"http://"，但文件似乎仍然无法在IE中加载，我想知道为什么会发生这种情况，因为在其他地方，代码似乎运行得很完美，如果我给它一个本地源代码，它也可以在IE中工作，我只想知道为什么CDN不能在IE中运行，我是不是错过了一些非常基本的东西？

剩下的代码是
