什么是 requestAnimationFrame?
使用 requestAnimationFrame 的好处?
与setInterval比较
与 CSS 动画比较
requestAnimationFrame | CSS animations |
---|---|
Requires writing JavaScript for each frame of the animation | Implement by defining CSS properties, run automatically. No need to manage frame updates |
Automatically adjust the frame rate, pauses when the tab is not visible | Runs independently of the JavaScript engine. CSS animations may not pause as efficiently when the tab is not visible |
Ideal for complex animations that involve multiple elements or need custom control over each frame | Best for simple, declarative animations like fading, scaling, rotating, and moving elements |
