我有一个 index.html 并需要 bootstrap.css 和 bootstrap.js。当我在桌面上缩小桌面浏览器时，导航栏会正确折叠。当我在我的移动设备上访问该网站时，除了导航栏之外，一切都是响应式的，它不会崩溃 这是我的代码 在头上

在页脚
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.11.3.min.js"><\/script>')</script>
<script src="js/bootstrap.js"></script>
<script src="js/plugins.js"></script>
<script src="js/main.js"></script>
最佳答案
您的脚本中需要有 bootstrap.min.js:
<script src="path/to/bootstrap.min.js"></script>
