var diff = moment(end).unix() - moment(start).unix();
moment.utc(moment.duration(diff).asMilliseconds()).format("HH:mm:ss.SSS");

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;
}

import * as moment from 'moment'
var sleep = require('sleep-promise');

(async function () {
    var t1 = new Date().getTime();
    await sleep(1000); 
    var t2 = new Date().getTime();
    var dur = moment.duration(t2-t1); 
    console.log(`${dur.hours()}h:${dur.minutes()}m:${dur.seconds()}s`);
})();

0h:0m:1s

只需moment.js，不需要任何其他插件

moment().startOf('day').seconds(duration).format('HH:mm:ss')

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"

如果你使用angular，添加这个到你的过滤器:

.filter('durationFormat', function () {
    return function (value) {
        var days = Math.floor(value/86400000);
        value = value%86400000;
        var hours = Math.floor(value/3600000);
        value = value%3600000;
        var minutes = Math.floor(value/60000);
        value = value%60000;
        var seconds = Math.floor(value/1000);
        return (days? days + ' days ': '') + (hours? hours + ' hours ': '') + (minutes? minutes + ' minutes ': '') + (seconds? seconds + ' seconds ': '')
    }
})

使用的例子

<div> {{diff | durationFormat}} </div>
