我在Bootstrap页面上做了一个完全相同的Carousel的拷贝,但是它根本不起作用。幻灯片不起作用,它总是停留在第一张图片中。我应该添加一些Javascript吗?我把jquery cdn放在bootstrap cdn的上面,就像我在很多关于可能的解决方案的帖子中看到的那样,但是它仍然不起作用。下面是html代码。

只需将图像文件更改为您的!
下面的代码对我来说很好用:

尝试从 Bootstrap 复制'CSS'链接开始页面和复制在头标记,而JS脚本应该在身体标记后。按照这个link有更多的理解。

将css文件添加到标记中,如

<head>
  <link rel="stylesheet" 
  href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
  </head>

并始终将js文件放在html代码的底部,在标记之后

.
    .
    .
    </body>
    <script defer src="variables.js"></script>    
    <script defer src="cotizadordeauto.js"></script>
    </html>
