javascript - 当我拥有所有参数时，为什么轮播不起作用？

问题描述

尝试使用引导程序中的轮播示例，但由于某种原因，顶部的轮播无法正常工作，我不确定问题是什么？我尝试搜索 youtube 视频和堆栈，但没有显示如何解决不滚动的问题。我想我可能缺少依赖项？以前一定有人遇到过这个问题，请建议新的编码..

解决方案

看起来您刚刚从 Bootstrap 演示页面复制并粘贴了 HTML，包括它们到 CSS 和 JS 文件的相对路径。这就是问题所在 - 您需要修复这些路径，以便它们在您自己的站点上工作。您可以使用 jQuery 和 Bootstrap 的 CDN 版本来实现这一点；注意前三行：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.bundle.min.js" integrity="sha384-6khuMg9gaYr5AxOqhkVIODVIvm9ynTT5J4V1cfthmT+emCG6yVmEZsRHdxlotUnm" crossorigin="anonymous"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
