BS5 轮播坏了，没有互动

Question

我想在我这边添加一个 bootstrap 5 旋转木马，但是交互部分（prev/next 按钮和每隔几秒自动滑动一次）不起作用 - 它只显示第一个.

轮播代码 100% 复制自 https://mdbootstrap.com/docs/standard/components/carousel/ and should work. The same code is also used in the official docs: https://getbootstrap.com/docs/5.0/components/carousel/#with-captions

似乎某种脚本被破坏了，开发工具没有显示任何错误。 CDN 链接是 bootstrap 5 教程中推荐的链接。

脚本标签可以在正文末尾找到。

Answer 1

在此处遵循 Bootstrap5 的官方文档：https://getbootstrap.com/docs/5.0/components/carousel/

它将 100% 有效。

回复后更新：

对我来说（我测试过）这里的代码很有魅力：

Answer 2

好的，所以我找到了解决方法：使用 data-bs-.. 而不是 data-mdb-...

我在 https://mdbootstrap.com/docs/standard/components/carousel/ 上学习了教程，因为官方文档最初不起作用，不幸的是他们使用了不同的标签属性。更改所有属性修复它。

显然 MDBootstrap 是一个与 bootstrap 略有不同的框架（不是分支，完全是从头开始编写的）。这个名字在我看来有点误导。
