一般倒计时的时间都是后台传来的然后渲染到页面，这里有2个简单的倒计时方式
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);
}
}
=3){
s=59;
m="0"+(Number(m)-1);
}
if(m.length>=3){
m='00';
s='00';
clearInterval(timer);
}
console.log(m+"分钟"+s+"秒");
}
timer=setInterval(countDown,1000);
}
如何使用
