是否有任何方法我可以使用moment.js格式方法持续时间对象?我在文档中找不到它，也没有看到它是持续时间对象的属性。
我希望能够做到以下几点:
var diff = moment(end).unix() - moment(start).unix();
moment.duration(diff).format('hh:mm:ss')
此外，如果有其他库可以轻松地容纳这种功能，我会很有兴趣推荐。
谢谢!

根据ni-ko-o-kin的回答:
meassurements = ["years", "months", "weeks", "days", "hours", "minutes", "seconds"];
withPadding = (duration) => {
var step = null;
return meassurements.map((m) => duration[m]()).filter((n,i,a) => {
var nonEmpty = Boolean(n);
if (nonEmpty || step || i >= a.length - 2) {
step = true;
}
return step;
}).map((n) => ('0' + n).slice(-2)).join(':')
}
duration1 = moment.duration(1, 'seconds');
duration2 = moment.duration(7200, 'seconds');
duration3 = moment.duration(604800, 'seconds');
withPadding(duration1); // 00:01
withPadding(duration2); // 02:00:00
withPadding(duration3); // 01:07:00:00:00

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')
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
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);
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>
简短版本(一行代码):
moment.duration(durationInMs).asHours()|0||"00" + ":" + moment.utc(durationInMs).format("mm:ss")
扩展的版本:
export const formatDuration = (durationInMs) => {
const hours = Math.floor(moment.duration(durationInMs).asHours()) || "00"
return hours + ":" + moment.utc(durationInMs).format("mm:ss")
}
