Question

我正在学校（巴西）为我的俱乐部制作一个网站，我想知道如何在我的网站上解决这个问题。按下移动设备中的三条线不会做任何事情。

Answer 1

嗨指的是Bootstrap Documentation。

我们的许多组件都需要使用JavaScript才能运行。具体来说，它们需要jQuery，Popper.js和我们自己的JavaScript插件。将以下内容放在页面末尾附近，就在结束前＆lt; / body＆gt;标记，以启用它们。 jQuery必须先来，然后是Popper.js，然后是我们的JavaScript插件。

您需要将这些行添加到页面中才能正常工作。

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>

我使用Bootstrap 4 Editor并复制了你的代码并且它完美地工作，因为编辑器内置了bootstrap javascripts。

Answer 2

您需要在关闭正文之前添加 jquery 和 bootstrap js才能进行切换。

注意：这里的顺序非常重要，首先放置jquery js链接然后再引导js。
