Bootstrap Scrollspy & Smooth-Scroll



我在滚动间谍和平滑滚动方面遇到了一些问题。请记住，我是这个东西的新手，只是对我的谷歌-fu很好。:)

这个问题非常令人沮丧，过去几天我一直在尝试很多不同的解决方案，但似乎没有一个有效。我正在使用引导 scrollspy 和平滑滚动在具有 4 个部分的单个页面上。每个部分在导航栏中都有自己的字形图标，当该部分滚动到时，该字形图标应变为粉红色。当我单击第二个图标时，它会按预期工作。当我点击第三个时，第二个保持粉红色，这是活动的。当我点击第 4 个时，第 3 个变为白色，第 2 个保持粉红色。此外，手动滚动时，只有前两个图标会改变颜色。如果你自己看到这种行为，可能会更容易。

这是我的代码。

更新：您的代码有效，只是没有在导航列表中正确设置锚点 ID。

href="third"和href="fourth"应该href="#third"和href="#fourth"
