不再需要(如果曾经有过的话)将持续时间转换为utc来解决这个问题。这就像将base10的“1”转换为二进制，然后说由于输出“1”看起来像base10，我们将没有任何问题，假设这是一个base10值，用于任何后续操作。

使用moment-duration-format，注意{trim: false}可以防止修剪:

moment.duration(1000000, "seconds").format("hh:mm:ss", { trim: false })
> "277:46:40"
moment.duration(0, "seconds").format("hh:mm:ss", { trim: false })
> "00:00:00"

让我们将其与不推荐的滥用utc的方法进行比较:

moment.utc(moment.duration(1000000, "seconds").asMilliseconds()).format('HH:mm:ss')
> "13:46:40"

这可以用于将前两个字符作为小时，最后两个字符作为分钟。同样的逻辑也适用于秒。

/** * PT1H30M -> 0130 * @param {ISO String} isoString * @return {string} absolute 4 digit number HH:mm */ const parseIsoToAbsolute = (isoString) => { const durations = moment.duration(isoString).as('seconds'); const momentInSeconds = moment.duration(durations, 'seconds'); let hours = momentInSeconds.asHours().toString().length < 2 ? momentInSeconds.asHours().toString().padStart(2, '0') : momentInSeconds.asHours().toString(); if (!Number.isInteger(Number(hours))) hours = '0'+ Math.floor(hours); const minutes = momentInSeconds.minutes().toString().length < 2 ? momentInSeconds.minutes().toString().padEnd(2, '0') : momentInSeconds.minutes().toString(); const absolute = hours + minutes; return absolute; }; console.log(parseIsoToAbsolute('PT1H30M')); <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment-with-locales.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>

// set up
let start = moment("2018-05-16 12:00:00"); // some random moment in time (in ms)
let end = moment("2018-05-16 12:22:00"); // some random moment after start (in ms)
let diff = end.diff(start);

// execution
let f = moment.utc(diff.asMilliseconds()).format("HH:mm:ss.SSS");
alert(f);

看看JSFiddle

原生javascript怎么样?

var formatTime = function(integer) {
    if(integer < 10) {
        return "0" + integer; 
    } else {
        return integer;
    }
}

function getDuration(ms) {
    var s1 = Math.floor(ms/1000);
    var s2 = s1%60;
    var m1 = Math.floor(s1/60);
    var m2 = m1%60;
    var h1 = Math.floor(m1/60);
    var string = formatTime(h1) +":" + formatTime(m2) + ":" + formatTime(s2);
    return string;
}

我们正在考虑在moment.js中为持续时间添加某种格式。参见https://github.com/timrwood/moment/issues/463

其他几个可能会有所帮助的库是http://countdownjs.org/和https://github.com/icambron/twix.js

你可以使用numeric .js来格式化你的时长:

numeral(your_duration.asSeconds()).format('00:00:00') // result: hh:mm:ss
