Question

我似乎无法让我的导航栏下拉菜单或汉堡包折叠正常工作。它们都出现了，但是当我单击它们中的任何一个时都不会发生任何操作。我在底部有 jQuery、popper 和 bootstrap js，顺序正确（我相信），我不确定我还能做什么。

我也没有任何与导航栏上的任何 id 交互的冲突 css 代码。

Answer 1

首先，您使用的是来自两个不同版本的 css 和 js：

4.3.1/css/bootstrap.min.css
3.4.1/js/bootstrap.min.js

选择一个版本并为两者使用相同的版本。

其次，您的 html 结构不正确。 nav.navbar 应该在 div.container-fluid 内。

<body>
  <div class="container-fluid">
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
      ...
    </nav>
    ...
  </div>
  ...
</body>

Bootstrap 下拉菜单和汉堡包崩溃不起作用
