滚动重绘前的JavaScript事件？ [英] javascript event before scroll redraw?

问题描述

问题是大多数浏览器在scoll之后绘制div，但是在之前 onscoll事件触发，所以最终得到1或2帧，其中div具有旧样式，但视口处于新的滚动位置。

$ b

如何防止这种情况？

解决方案

p>也许将body设置为overflow：hidden启动，并将其更改为overflow：在第一个onscroll触发时自动运行。

I have a javascript function on the onscoll event to change a div's style.

The problem is that most browsers draw the div after a scoll but before the onscoll event fires, so you end up with 1 or 2 frames where the div has the old style but the viewport is at the new scroll position. This can cause ugly flickering.

How do you prevent this?

解决方案

Maybe set the body to overflow:hidden to start, and change it to overflow:auto once the first onscroll fires.
