js判斷頁面是否長時間未操作

const waitOperate = (callback, second) => {
  let count = 0;
  let x;
  let y;
  let timer;
  //監聽鼠標
  document.onmousemove = function (event) {
    const x1 = event.clientX;
    const y1 = event.clientY;
    if (x != x1 || y != y1) {
      count = 0;
    }
    x = x1;
    y = y1;
  };
  //監聽鍵盤
  document.onkeydown = function () {
    count = 0;
  };
  function countTime() {
    count++;
    if(count >=  second){
      callback();
      count = 0;
      // clearInterval(timer);
    }
  }
  timer = setInterval(countTime, 1000)
  ;
