使用JavaScript在空闲时隐藏鼠标光标

let timer;
const hideCursor = () => {
  document.body.style.cursor = 'none';
};
const showCursor = () => {
  document.body.style.cursor = 'default';
};
const resetTimer = () => {
  clearTimeout(timer);
  timer = setTimeout(hideCursor, 2000);
};
document.addEventListener('mousemove', resetTimer);
document.addEventListener('mouseleave', resetTimer);
document.addEventListener('mouseenter', resetTimer);
resetTimer();
