JS倒计时：

// 倒计时
let end_time = "结束时间戳"
countDown(end_time)
function countDown(end_time) {
let now_time = new Date().getTime()
let times = (end_time - now_time) / 1000 // times单位为秒
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);
}else{
$('#countDown').text(`00:00:00:00`)
return
}
if (day <= 9) day = '0' + day;
if (hour <= 9) hour = '0' + hour;
if (minute <= 9) minute = '0' + minute;
if (second <= 9) second = '0' + second;
//
// alert(day+"天:"+hour+"小时："+minute+"分钟："+second+"秒");
$('#countDown').text(`${day}:${hour}:${minute}:${second}`)
setTimeout(()=>{

},1000)
