javascript - Bootstrap 5 - Carousel 不会滑动到下一个图像 - 从 bootstrap 4 升级到 bootstrap 5

问题描述

所以我下载了 bootstrap 5 库 -compiled css and js和source files. 我已经尝试过这两种方法——据我所知，css 加载得很好——但是，我无法从 boostrap 4 上的相关帖子中获得这个示例，它应该适用于 bootstrap 5 ......我试图避免使用 CDN 提供库，因此我下载了它们。当我使用示例中提供的 CDN 时，它就像一个魅力。

有人可以指出我让旋转木马工作所缺少的东西吗？我需要参考哪些文件才能使其滑动？

（这里有一些代码，所以我不会大喊大叫）

我正在使用 dJango，当我检查控制台时，我没有资源错误。

再一次，当我使用 BS 4 CDN 时，一切正常......

解决方案

要从版本 4 迁移到 5，您必须更改数据值，例如 data-bs-target 而不是 data-target。

在您的情况下，只需进行简单的更改

<!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- Bootstrap CSS -->
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
