新的日期().toString()。分割(" ")[4];

结果15:08:03

这是最简单的方法。

new Date(sec * 1000).toISOString().substr(11, 8)

你可以使用moment .js的moment-duration-format插件:

Var秒= 3820; Var duration =时刻。持续时间(秒,“秒”); Var format = duration.format("hh:mm:ss"); console.log(格式化);/ / 01:03:40 <！——Moment.js库——> .js库 < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js " > < /脚本> <！——moment-duration-format插件——> < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment-duration-format/1.3.0/moment-duration-format.min.js " > < /脚本>

看看这把小提琴

            //secondsToTime();
            var t = wachttijd_sec; // your seconds
            var hour = Math.floor(t/3600);
            if(hour < 10){
                hour = '0'+hour;
            }
            var time = hour+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2);
            //would output: 00:00:00 > +100:00:00

即使超过24小时也能保持倒计时

下面是它的es6版本:

export const parseTime = (time) => { // send time in seconds
// eslint-disable-next-line 
let hours = parseInt(time / 60 / 60), mins = Math.abs(parseInt(time / 60) - (hours * 60)), seconds = Math.round(time % 60);
return isNaN(hours) || isNaN(mins) || isNaN(seconds) ? `00:00:00` : `${hours > 9 ? Math.max(hours, 0) : '0' + Math.max(hours, 0)}:${mins > 9 ? Math.max(mins, 0) : '0' + Math.max(0, mins)}:${seconds > 9 ? Math.max(0, seconds) : '0' + Math.max(0, seconds)}`;}

这很简单，

function toTimeString(seconds) {
  return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}
