html - 导航栏折叠切换不起作用（Bootstrap5）

问题描述

我是 Bootstrap 的新手。从 FreeCodeCamp观看本 教程。一步一步地跟随，但在 1 小时 11 分钟左右，他检查了他网站的响应能力。在降低屏幕宽度时，他的 NavBar 会折叠（我的也是如此），但与他不同的是，我的 NavBar 在折叠时不会切换。

这是代码：

<!doctype html>
<html class="no-js" lang="">

        <meta charset="utf-8">
        <meta http-equiv="x-ua-compatible" content="ie=edge">

        <script src="/assets/js/bootstrap.bundle.min.js" type="text/javascript"></script>
    </body>
</html>

标签： htmlcss

解决方案

我发现了问题，我的脚本链接错误：

 <script src="/assets/js/bootstrap.bundle.min.js" type="text/javascript"></script>

它应该是：

 <script src="./assets/js/bootstrap.bundle.min.js" type="text/javascript"></script>
