Bootstrap 导航栏切换按钮无法正常工作（HTML 内）

Question

当我以较低的分辨率 (<768px) 打开我的网站时，会显示菜单按钮（3 条），但是当我单击它时它不会显示折叠的导航栏。我究竟做错了什么？我认为我已经正确链接了所有内容。

Answer 2

在无效位置引用 bootstrap.js

    <script src="js/bootstrap.min.js"></script>

修复如下：

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
