我正在使用 bootstrap 4 并希望在我的按钮和 anchor 标记上显示工具提示。但工具提示仅显示在 anchor 标记上，而不显示在按钮上。即使工具提示确实显示，它也不会显示任何样式，这意味着它是白色的，并且看起来不像 Bootstrap 文档中那样。
这是我的代码，它是一个 ejs 模板。

到目前为止我可以确认的是
- poper，jquery和bootstrap js的顺序是正确的
- 工具提示在所有元素的 jquery 文档就绪函数中初始化
data-toggle="tooltip"存在于两个元素内
最佳答案
这是您正在使用的代码吗？当前代码适用于我的所有浏览器(EI、Edge、FF 和 Chrome)。您使用的是什么浏览器，是否启用了 JS？
这是基于您的示例的工作代码:jsfiddle.net/zergioz/tbgrfv4z - 将鼠标悬停在不同的状态上。
关于javascript - Bootstrap 4 工具提示未按样式显示。而且它仅适用于 anchor 标记，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57462621/
