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(()=>{
- countDown(end_time)
- },1000)
- }
