添加初始化事件

setTimeout(function(){

const countDown = (second) => {

  const s = second % 60;

  const m = Math.floor(second / 60);

  return m+":"+(s<10?'0'+s:s);

};

let time = 5 * 60;

const timer = setInterval(() => {

  const show = countDown(time--);

  $('div[widgetname=LABEL0]').find('.fr-label').html(show)

  if(time < 0) {

    console.log('倒计时结束！重新开始');

    time=5*60;

  }

}, 1000);

},0) 

  把这段代码放进去 看下效果

    let maxtime = 5 * 60;

    function CountDown() {

      if (maxtime >= 0) {

        min = Math.floor(maxtime / 60);

        sec = Math.floor(maxtime % 60);

        msg = `${min}:${sec}`;

        console.log(msg);

        document.querySelector("h2").innerHTML = msg;

        --maxtime;

      } else {

        clearInterval(time);

      }

      if (maxtime == 0) {

        maxtime = 5 * 60;

        time;

      }

    }

    let time = setInterval("CountDown()", 10);
