html - 为什么我的引导切换器不切换？

问题描述

我已按照说明将 javascript 包包含到我的文件中。但是，每当我单击切换按钮时，它根本不会切换，为什么会这样？它与我的软件包版本有关吗？

我已经包含了一些 Django 模板语法，请忽略那些

标签： htmlbootstrap-4

解决方案

您正在使用 bootstrap 5 语法data-bs-toggle

但是您使用 bootstrap 4 更改data-bs-toggle为data-toggle

查看 bootstrap 4 文档 https://getbootstrap.com/docs/4.6/components/dropdowns/
