Mastering rAF means understanding its callback timing, using the high-resolution timestamp parameter for frame-independent animation, building efficient animation loops, and leveraging advanced I understand that the purpose of rAF is for consistently smooth animations, and I might run the risk of making my animation choppy, but right now it seems to run at drastically different speeds pretty Use of the requestAnimationFrame () method: The requestAnimationFrame () method tells the browser that you wish to perform an animation and requests that the browser call a specified function to But using rAF efficiently requires careful planning, especially when handling multiple animations. But to truly leverage rAF, you raf 充分利用显示器的刷新机制，执行频率和显示屏的刷新频率保持同步，利用这个刷新频率进行页面重绘。 也就是说在我的电脑上，raf 函数每秒执行 165 次。 也就是 6 ms 执行一次， 今天正好要用上RAF。之前也说过它的缺点，一是不能设置间隔时间，二是我觉得如果一个页面有多个动画，则需要调用N个requestAnimationFrame。 文章浏览阅读668次，点赞8次，收藏20次。是现代 Web 动画的黄金标准与屏幕刷新率同步 → 更流畅；后台自动暂停 → 更省电；浏览器优化调度 → 更高性能。🎯最佳实践：只要涉及视 Throttle a function by requestAnimationFrame. jsTimers-rAF hack is useful if you want use So far, the typically recommended best (or least bad) timing method has been a single requestAnimationFrame (RAF) JavaScript function call within which one would give the display The RAF loop (which is going on independently in the background) should improve the precision of the timing in this RAF call. function delay(cb, delayTime, everyTimeCb){ var cancel = false; delayTime = delayTime || 0; (function(){ var baseTime; var Throttle a function by requestAnimationFrame. 基本概念和使用方法什么是 requestAnimationFrame？requestAnimationFrame（简称 rAF）是浏览器提供的专门用于动画执行的 API，它会在浏览器下一次重绘之前调用指定的回调函数。 基本语法// 请求 Can I call requestAnimationFrame multiple times?
