【问题讨论】：

至少对我而言，您的引导 javascript 脚本未正确包含。它使用本地主机。不，javascript没有切换。也许它适合你？

【解决方案1】：

您似乎没有在头脑中添加 Javascript。将以下行添加到您的 HTML <head> 标记（Jquery 和 Bootstrap JS）：

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
