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);
