【问题描述】:
我正在使用 Bootstrap scrollspy 来更新导航栏。我想更改navbar 上突出显示的活动li 的颜色以匹配匹配部分的background-color。但它是动态内容
我知道data-spy 属性的作用以及如何使用它,但我不知道scrollspy 插件在bonnet 下的真正工作原理。所以我可以编写自己的代码来处理它。

我建议进行编辑以澄清您的实际问题。一般询问插件的工作原理过于宽泛,会导致您的问题被关闭。请仔细阅读我建议的编辑,以确保它仍在询问您想要什么。此外,如果您发布到目前为止所拥有的任何代码而不是链接到 W3Schools,它可能会有所帮助。干杯!

@AndrewMyers 我没有找到任何方法来实现它,这就是为什么我没有任何代码你认为我的问题不清楚,即我没有问我想要做什么

对我之前的(现已删除)评论感到抱歉。当我对我是否理解这个问题有疑问时,我实际上已经回答并删除了我的答案。我以为你的问题几乎要被删除了,但是现在有人好心指出我仍然可以取消删除我的答案,现在可以了。您的问题明天不再符合删除条件。
