html - Bootstrap 4折叠按钮不可点击

问题描述

我正在做一个网站。我计划有一个折叠的菜单，但折叠的按钮似乎不起作用。

 <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它，当我将它粘贴到我的dreamweaver 并加载它时，栏和折叠按钮都在那里。

解决方案

问题肯定出在您的引导程序依赖文件上。使用 js 和 css 的 CDN，页面将很容易工作，或者脱机工作，您应该下载引导文件并按正确的顺序放置并按正确的顺序导入相同的 文件。 你可以试试这个（使用 Bootstrap CDN）：
