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;
}

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());

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”

我认为这是目前为止最快的性能:

var t = 34236; // your seconds
var time = ('0'+Math.floor(t/3600) % 24).slice(-2)+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2)
//would output: 09:30:36

我是这样做的。它似乎工作得相当好，而且非常紧凑。(不过，它使用了很多三元操作符)

function formatTime(seconds) {
  var hh = Math.floor(seconds / 3600),
    mm = Math.floor(seconds / 60) % 60,
    ss = Math.floor(seconds) % 60;
  return (hh ? (hh < 10 ? "0" : "") + hh + ":" : "") + ((mm < 10) && hh ? "0" : "") + mm + ":" + (ss < 10 ? "0" : "") + ss
}

.．.对于格式化字符串…

String.prototype.toHHMMSS = function() {
  formatTime(parseInt(this, 10))
};

新的日期().toString()。分割(" ")[4];

结果15:08:03
