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>

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;
}

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

使用这个插件Moment Duration Format。

例子:

moment.duration(123, "minutes").format("h:mm");

你不需要.format。像这样使用持续时间:

const duration = moment.duration(83, 'seconds');
console.log(duration.minutes() + ':' +duration.seconds());
// output: 1:23

我在这里找到了这个解决方案:https://github.com/moment/moment/issues/463

编辑:

用秒、分和小时填充:

const withPadding = (duration) => {
    if (duration.asDays() > 0) {
        return 'at least one day';
    } else {
        return [
            ('0' + duration.hours()).slice(-2),
            ('0' + duration.minutes()).slice(-2),
            ('0' + duration.seconds()).slice(-2),
        ].join(':')
    }
}

withPadding(moment.duration(83, 'seconds'))
// 00:01:23

withPadding(moment.duration(6048000, 'seconds'))
// at least one day

如果必须显示所有的小时(超过24小时)，如果小时之前的'0'是不必要的，那么格式化可以用一小行代码完成:

Math.floor(duration.as('h')) + moment.utc(duration.as('ms')).format(':mm:ss')
