我目前正在使用 Bootstrap 构建一个网站，并且已经了解了实现部分。我已经检查过，看来我已经正确安装了 Bootstrap 和 Jquery，但是当我在移动大小的屏幕上切换下拉菜单时，没有任何反应。我知道以前有人问过这个问题，并尝试用这些解决方案解决我的问题，但没有任何帮助。

最佳答案
试试这个:
<nav class='navbar-default navbar' >
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a>
</div>
</nav>
