function formatTime(seconds) {
    return [
        parseInt(seconds / 60 / 60),
        parseInt(seconds / 60 % 60),
        parseInt(seconds % 60)
    ]
        .join(":")
        .replace(/\b(\d)\b/g, "0$1")
}

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)}`;}

s2t=function (t){
  return parseInt(t/86400)+'d '+(new Date(t%86400*1000)).toUTCString().replace(/.*(\d{2}):(\d{2}):(\d{2}).*/, "$1h $2m $3s");
}

s2t(123456);

结果:

1d 10h 17m 36s

我推荐使用普通的javascript，使用Date对象。(要获得更简短的解决方案，请使用toTimeString，请参阅第二个代码片段。)

var seconds = 9999;
// multiply by 1000 because Date() requires miliseconds
var date = new Date(seconds * 1000);
var hh = date.getUTCHours();
var mm = date.getUTCMinutes();
var ss = date.getSeconds();
// If you were building a timestamp instead of a duration, you would uncomment the following line to get 12-hour (not 24) time
// if (hh > 12) {hh = hh % 12;}
// These lines ensure you have two-digits
if (hh < 10) {hh = "0"+hh;}
if (mm < 10) {mm = "0"+mm;}
if (ss < 10) {ss = "0"+ss;}
// This formats your string to HH:MM:SS
var t = hh+":"+mm+":"+ss;
document.write(t);

(当然，创建的Date对象将有一个与之关联的实际日期，但该数据是无关的，因此出于这些目的，您不必担心它。)

编辑(简短的解决方案):

使用toTimeString函数并对空白进行分割:

var seconds = 9999; // Some arbitrary value
var date = new Date(seconds * 1000); // multiply by 1000 because Date() requires miliseconds
var timeStr = date.toTimeString().split(' ')[0];

toTimeString给出'16:54:58 GMT-0800 (PST)'，对第一个空格进行分割给出'16:54:58'。

我喜欢Powtac的答案，但我想在angular.js中使用它，所以我用他的代码创建了一个过滤器。

.filter('HHMMSS', ['$filter', function ($filter) {
    return function (input, decimals) {
        var sec_num = parseInt(input, 10),
            decimal = parseFloat(input) - sec_num,
            hours   = Math.floor(sec_num / 3600),
            minutes = Math.floor((sec_num - (hours * 3600)) / 60),
            seconds = sec_num - (hours * 3600) - (minutes * 60);

        if (hours   < 10) {hours   = "0"+hours;}
        if (minutes < 10) {minutes = "0"+minutes;}
        if (seconds < 10) {seconds = "0"+seconds;}
        var time    = hours+':'+minutes+':'+seconds;
        if (decimals > 0) {
            time += '.' + $filter('number')(decimal, decimals).substr(2);
        }
        return time;
    };
}])

它在功能上是相同的，除了我添加了一个可选的小数字段来显示小数秒。像使用其他过滤器一样使用它:

{{elapsedTime | HHMMSS}}显示:01:23:45

{{elapsedTime | HHMMSS: 3}}显示:01:23:45.678

function toHHMMSS(seconds) {
    var h, m, s, result='';
    // HOURs
    h = Math.floor(seconds/3600);
    seconds -= h*3600;
    if(h){
        result = h<10 ? '0'+h+':' : h+':';
    }
    // MINUTEs
    m = Math.floor(seconds/60);
    seconds -= m*60;
    result += m<10 ? '0'+m+':' : m+':';
    // SECONDs
    s=seconds%60;
    result += s<10 ? '0'+s : s;
    return result;
}

例子

    toHHMMSS(111); 
    "01:51"

    toHHMMSS(4444);
    "01:14:04"

    toHHMMSS(33);
    "00:33"
