示例1: wrapperRaf

// Support call raf with delay specified frame
export default function wrapperRaf(callback: () => void, delayFrames: number = 1): number {
  const myId: number = id++;
  let restFrames: number = delayFrames;

  function internalCallback() {
    restFrames -= 1;

    if (restFrames <= 0) {
      callback();
      delete ids[myId];
    } else {
      ids[myId] = raf(internalCallback);
    }
  }

  ids[myId] = raf(internalCallback);

  return myId;
