- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
有没有办法在平滑滚动(参见示例)结束时获得回调?
我唯一能想到的就是观察 scroll
的缺失事件,但没有办法将它们与 anchor 点击联系起来 - 您如何将它们与只是自己滚动页面的用户区分开来?
html {
scroll-behavior: smooth;
}

更新:现在你可以检测按钮点击和滚轮滚动,鼠标点击栏和页面上/下
var btnClick = false;
