    倒计时-setInterval

    function countDown(times){
      var timer=null;
      timer=setInterval(function(){
        var day=0,hour=0,minute=0,second=0;
        if(times > 0){
          day = Math.floor(times / (60 * 60 * 24));
          hour = Math.floor(times / (60 * 60)) - (day * 24);
          minute = Math.floor(times / 60) - (day * 24 * 60) - (hour * 60);
          second = Math.floor(times) - (day * 24 * 60 * 60) - (hour * 60 * 60) - (minute * 60);
        }
        if (day <= 9) day = '0' + day;
        if (hour <= 9) hour = '0' + hour;
        if (minute <= 9) minute = '0' + minute;
        if (second <= 9) second = '0' + second;
        console.log(day+"天:"+hour+"小时:"+minute+"分钟:"+second+"秒");
        times--;
      },1000);
      if(times<=0){
        clearInterval(timer);
      }
    }
    countDown(10000);//传递需要的时间(秒)
