正如Cleiton在他的回答中指出的，moment.js可以用于:

moment().startOf('day')
        .seconds(15457)
        .format('H:mm:ss');

var time1 = date1.getTime();
var time2 = date2.getTime();
var totalMilisec = time2 - time1;

alert(DateFormat('hh:mm:ss',new Date(totalMilisec)))

 /* ----------------------------------------------------------

function DateFormat(formatString,date){
    if (typeof date=='undefined'){
    var DateToFormat=new Date();
    }
    else{
        var DateToFormat=date;
    }
    var DAY         = DateToFormat.getDate();
    var DAYidx      = DateToFormat.getDay();

    var SECONDS     = DateToFormat.getSeconds();

    var arrMonths = new Array("January","February","March","April","May","June","July","August","September","October","November","December");

        strMONTH=MONTH;

        strDAY = "0" + DAY;
    else
        strDAY=DAY;
    if(parseInt(HOUR)< 10 && HOUR.toString().length < 2)
        strHOUR = "0" + HOUR;
    else

        break;
        //More cases to meet your requirements.
    }
}

下面是将秒转换为hh-mm-ss格式的代码:

var measuredTime = new Date(null);
measuredTime.setSeconds(4995); // specify value of SECONDS
var MHSTime = measuredTime.toISOString().substr(11, 8);

在JavaScript中获得从将秒转换为HH-MM-SS格式的替代方法

在JavaScript Date方法的帮助下，你可以在没有任何外部JavaScript库的情况下做到这一点，如下:

const date = new Date(null);
date.setSeconds(SECONDS); // specify value for SECONDS here
const result = date.toISOString().slice(11, 19);

或者，按照@Frank的评论;一句话:

new Date(SECONDS * 1000).toISOString().slice(11, 19);

对于HH:MM:SS的特殊情况。MS (eq: "00:04:33.637")， FFMPEG用来指定毫秒。

[-] [HH: MM: SS(打烊……) HH表示小时数，MM表示分钟数 最大值为2位，SS为最大值为2的秒数 位数。最后的m表示SS的十进制值。

/* HH:MM:SS.MS to (FLOAT)seconds ---------------*/ function timerToSec(timer){ let vtimer = timer.split(":") let vhours = +vtimer[0] let vminutes = +vtimer[1] let vseconds = parseFloat(vtimer[2]) return vhours * 3600 + vminutes * 60 + vseconds } /* Seconds to (STRING)HH:MM:SS.MS --------------*/ function secToTimer(sec){ let o = new Date(0) let p = new Date(sec*1000) return new Date(p.getTime()-o.getTime()) .toISOString() .split("T")[1] .split("Z")[0] } /* Example: 7hours, 4 minutes, 33 seconds and 637 milliseconds */ const t = "07:04:33.637" console.log( t + " => " + timerToSec(t) + "s" ) /* Test: 25473 seconds and 637 milliseconds */ const s = 25473.637 // "25473.637" console.log( s + "s => " + secToTimer(s) )

示例使用，毫秒传输计时器:

/* Seconds to (STRING)HH:MM:SS.MS --------------*/ function secToTimer(sec){ let o = new Date(0) let p = new Date(sec*1000) return new Date(p.getTime()-o.getTime()) .toISOString() .split("T")[1] .split("Z")[0] } let job, origin = new Date().getTime() const timer = () => { job = requestAnimationFrame(timer) OUT.textContent = secToTimer((new Date().getTime() - origin) / 1000) } requestAnimationFrame(timer) span {font-size:4rem} <span id="OUT"></span> <br> <button onclick="origin = new Date().getTime()">RESET</button> <button onclick="requestAnimationFrame(timer)">RESTART</button> <button onclick="cancelAnimationFrame(job)">STOP</button>

绑定到媒体元素的示例用法

/* Seconds to (STRING)HH:MM:SS.MS --------------*/ function secToTimer(sec){ let o = new Date(0) let p = new Date(sec*1000) return new Date(p.getTime()-o.getTime()) .toISOString() .split("T")[1] .split("Z")[0] } VIDEO.addEventListener("timeupdate", function(e){ OUT.textContent = secToTimer(e.target.currentTime) }, false) span {font-size:4rem} <span id="OUT"></span><br> <video id="VIDEO" width="400" controls autoplay> <source src="https://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4"> </video>

在问题之外，那些用php编写的函数:

<?php 
/* HH:MM:SS to (FLOAT)seconds ------------------*/
function timerToSec($timer){
  $vtimer = explode(":",$timer);
  $vhours = (int)$vtimer[0];
  $vminutes = (int)$vtimer[1];
  $vseconds = (float)$vtimer[2];
  return $vhours * 3600 + $vminutes * 60 + $vseconds;
}
/* Seconds to (STRING)HH:MM:SS -----------------*/
function secToTimer($sec){
  return explode(" ", date("H:i:s", $sec))[0];  
}

这是一个非常简单的任务，但你们中的一些人直接推荐了Moment.js，或者创建了一些最丑陋的函数来解析一些秒…

transform(time: number): string {
    if (time != null) {
        const hours: number = Math.floor(time / 3600);
        const minutes: number = Math.floor((time - (hours * 3600)) / 60);
        const seconds: number = time - (hours * 3600) - (minutes * 60);
        return [hours, (minutes < 10) ? '0' + minutes : minutes, (seconds < 10) ? '0' + seconds : seconds].join(':');
    } else {
        return '00:00:00';
    }
}

这在任何情况下都适用……
