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

将时刻持续时间格式化为字符串

var duration = moment.duration(86400000); //value in milliseconds
var hours = duration.hours();
var minutes = duration.minutes();
var seconds = duration.seconds();
var milliseconds = duration.milliseconds();

var date = moment().hours(hours).minutes(minutes).seconds(seconds).millisecond(milliseconds);
if (is12hr){
    return date.format("hh:mm:ss a");
}else{
    return date.format("HH:mm:ss");
}

// 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

如果你愿意使用不同的javascript库，numeric .js可以将秒格式化如下(例如1000秒):

var string = numeral(1000).format('00:00');
// '00:16:40'

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
