Bootstrap 4折叠按钮不可点击

标签： html css twitter-bootstrap

我正在一个网站上。我本来打算有一个折叠菜单，但是折叠按钮似乎不起作用。

 <link rel="stylesheet" type="text/css" href="css/style.css"/>
 <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
 <link rel="stylesheet" type="text/css" href="css/bootstrap-grid.css"/>
 <link rel="stylesheet" type="text/css" href="css/bootstrap-reboot.css"/>

</head>

<body>

<div class="pos-f-t">
<div class="collapse" id="navbarToggleExternalContent">
<div class="bg-dark p-4">
  <h4 class="text-white">Title here.</h4>
  <span class="text-muted">Text here.</span>
</div>
</div>
<nav class="navbar navbar-dark bg-dark">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
  <span class="navbar-toggler-icon"></span>
 </button>
 </nav>
 </div>



 <!-- SCRIPT -->
 <script  src="js/bootstrap.js"></script>
 <script  src="js/bootstrap.bundle.js"></script>
 <script  src="js/jquery-1.11.2.min.js"></script>
 <!-- END OF SCRIPT -->
 </body>


 </html>

我从引导站点本身复制了此代码，然后将其粘贴到我的Dreamweaver上并加载了它，栏和折叠按钮都在那儿。

尝试使用live link中的css and script或下载库，然后使其工作脱机。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

看上去您的javascript文件的顺序不正确。

您也不需要bootstrap.js和bootstrap.bundle.js，只需使用捆绑包即可，因为它是1个组合文件中的bootstrap.js + popper.js（请参阅：https://getbootstrap.com/docs/4.1/getting-started/contents/#js-files）。

所以...尝试将您的JavaScript更改为：

<!-- SCRIPT -->
<script  src="js/jquery-1.11.2.min.js"></script>
<script  src="js/bootstrap.bundle.js"></script>
<!-- END OF SCRIPT -->

编辑：看来您的css文件顺序也不正确，而且您不需要全部。.将它们更改为：

<link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
<link rel="stylesheet" type="text/css" href="css/style.css"/>

您可能会丢失项目文件夹中的某些CSS或JS文件。

问题肯定与您的引导程序依赖文件有关。使用CDN用于js和css，页面可以轻松工作，或者脱机工作，您应该下载引导程序文件，并应以正确的顺序放置并以正确的顺序导入 Refer。
您可以尝试此操作（使用Bootstrap CDN）：
