Question

嗨，大家好？请我需要帮助，我想要一种情况在特定时间，第一个计时器应停止计数，而第二个计时器计时器执行并更新“ BREAK TIME”，其方式是刷新，直到第二个计时器完成执行，第一个计时器才执行，反之亦然。

<script>


 let element = document.querySelector('#countdown');
    let breakTime = document.querySelector("#countdownbreak"),myD=true;
    function TimeFii(){
      time_difference = (60*1) -(((Date.now()-localStorage.getItem('realTime'))/1000) | 0); //60 if duration = 60*1
      hours = (time_difference/3600) | 0;
      minutes = ((time_difference % 36000) / 60)  | 0;
      seconds = (time_difference %60)|0;
      hours = hours<10 ? "0"+hours:hours
      minutes =  minutes < 10 ? "0"+minutes:minutes//00
      seconds = seconds <10 ?"0"+seconds:seconds
        uniseconds = seconds;
        element.textContent = minutes+":"+seconds;
        if(time_difference<=0){
          var start = Date.now()+100;`enter code here`
          localStorage.setItem('realTime',start);
        }
        if(seconds==39){
          stop();
          resetFii();
          element.innerHTML =""
          localStorage.setItem('noStart',myD)
          startFiiTimer(TimeFiiBreak);
        }
    }

    function TimeFiiBreak(){
      time_difference = (60*3) -(((Date.now()-localStorage.getItem('realBTime'))/1000) | 0); //60 if duration = 60*1
      hours = (time_difference/3600) | 0;
      minutes = ((time_difference % 36000) / 60)  | 0;
      seconds = (time_difference %60)|0;
      hours = hours<10 ? "0"+hours:hours
      minutes =  minutes < 10 ? "0"+minutes:minutes//00
      seconds = seconds <10 ?"0"+seconds:seconds
        uniseconds = seconds;
        breakTime.textContent = "BREAK TIME:"+minutes+":"+seconds;
        if(time_difference<=0){
          var start = Date.now()+100;
          localStorage.setItem('realBTime',start);
        }
        if(seconds==40){
          stopB();
          resetBFii();
          startFiiTimer(TimeFii);

        }
    }

    function startFiiTimer(fun){
      return setInterval(fun,100);
    }


    function resetFii(){
        return localStorage.removeItem('realTime');
    }
    function stop(){
      return clearInterval(TimeFii)
    }

    function resetBFii(){
        return localStorage.removeItem('realBTime');
    }
    function stopB(){
      return clearInterval(TimeFii)
    }
    window.onload = function (){
      if(myD !=false){
        startFiiTimer(TimeFii);
      }
    }

</script>

请运行上面的代码段，但不完全如我所愿，您可以访问fastplay24.com来查看计时器示例。谢谢

Answer 1

setInterval（）返回一个计时器ID，在调用clearInterval（）时需要使用该ID，而不是函数本身。像这样：

idtimerfii = setInterval(fun,100);

clearInterval(idtimerfii)

我需要一个同时工作的倒数计时器
