Window: cancelAnimationFrame() method

The window.cancelAnimationFrame() method cancels an animation frame request previously scheduled through a call to window.requestAnimationFrame().

Syntax

cancelAnimationFrame(requestID)

Parameters

requestID: The ID value returned by the call to window.requestAnimationFrame() that requested the callback.

Return value

None (undefined).

Examples

const start = document.timeline.currentTime;

let myReq;

function step(timestamp) {
 const progress = timestamp - start;
 d.style.left = `${Math.min(progress / 10, 200)}px`;
 if (progress < 2000) {
 // it's important to update the requestId each time you're calling requestAnimationFrame
 myReq = requestAnimationFrame(step);
 }
}
myReq = requestAnimationFrame(step);
// the cancellation uses the last requestId
cancelAnimationFrame(myReq);
