Question

我目前正在使用Bootstrap构建一个网站，并且已经获得了实施部分的库存。我已经检查了，看来我已经正确安装了Bootstrap和Jquery，但当我在移动大小的屏幕上切换下拉菜单时没有任何反应。我知道以前曾经问过这个问题并试图用这些解决方案来解决我的问题，但没有任何帮助。

Answer 1

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>
