Bootstrap 3.3.2 导航栏下拉菜单切换在移动设备或桌面上不可点击

Question

通过移动设备或桌面放大访问时，下拉菜单切换按钮不起作用。它似乎不可点击，因为点击或触摸时没有任何反应。

我已经尝试了一些在其他问题上找到的解决方案，即使是 bootstrap 的旧版本，但没有任何效果。谢谢

您需要在包含 bootstrap.min.js 之前包含 jQuery。

所以在 bootstrap 之后包括：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
