我会给artem的答案投票，但我是一个新海报。我确实扩展了他的解决方案，虽然不是OP要求的如下

    t=(new Date()).toString().split(" ");
    timestring = (t[2]+t[1]+' <b>'+t[4]+'</b> '+t[6][1]+t[7][0]+t[8][0]);

得到

0410月16:31:28太平洋时间

这对我很有用……

但如果你从一个时间量开始，我会用两个函数;一个用于格式化和填充，一个用于计算:

function sec2hms(timect){

  if(timect=== undefined||timect==0||timect === null){return ''};
  //timect is seconds, NOT milliseconds
  var se=timect % 60; //the remainder after div by 60
  timect = Math.floor(timect/60);
  var mi=timect % 60; //the remainder after div by 60
  timect = Math.floor(timect/60);
  var hr = timect % 24; //the remainder after div by 24
  var dy = Math.floor(timect/24);
  return padify (se, mi, hr, dy);
}

function padify (se, mi, hr, dy){
  hr = hr<10?"0"+hr:hr;
  mi = mi<10?"0"+mi:mi;
  se = se<10?"0"+se:se;
  dy = dy>0?dy+"d ":"";
  return dy+hr+":"+mi+":"+se;
}

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'。

我是这么做的

function timeFromSecs(seconds)
{
    return(
    Math.floor(seconds/86400)+'d :'+
    Math.floor(((seconds/86400)%1)*24)+'h : '+
    Math.floor(((seconds/3600)%1)*60)+'m : '+
    Math.round(((seconds/60)%1)*60)+'s');
}

timeFromSecs(22341938)将返回“258d 14h 5m 38s”

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)}`;}

String.prototype.toHHMMSS = function () {
    var sec_num = parseInt(this, 10); // don't forget the second param
    var hours   = Math.floor(sec_num / 3600);
    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
    var 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;}
    return hours+':'+minutes+':'+seconds;
}

你现在可以这样使用它:

alert("5678".toHHMMSS());

工作代码片段:

String.prototype.toHHMMSS = function () { var sec_num = parseInt(this, 10); // don't forget the second param var hours = Math.floor(sec_num / 3600); var minutes = Math.floor((sec_num - (hours * 3600)) / 60); var 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;} return hours + ':' + minutes + ':' + seconds; } console.log("5678".toHHMMSS());

使用moment.js库:

function humanizeDuration(input, units ) { 
  // units is a string with possible values of y, M, w, d, h, m, s, ms
  var duration = moment().startOf('day').add(units, input),
    format = "";

  if(duration.hour() > 0){ format += "H [hours] "; }

  if(duration.minute() > 0){ format += "m [minutes] "; }

  format += " s [seconds]";

  return duration.format(format);
}

这允许您指定任何持续时间，无论是小时、分钟、秒、磨，并返回人类可读的版本。
