我使用:

var duration = moment.duration("09:30");
var str = moment(duration._data).format("HH:mm");

我在var str中得到"09:30"

如果diff是一瞬间

var diff = moment(20111031) - moment(20111010);
var formated1 = moment(diff).format("hh:mm:ss");
console.log("format 1: "+formated1);

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

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

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

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>
