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!

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

如果你使用Angular >2，我做了一个受@hai-alaluf answer启发的Pipe。
import {Pipe, PipeTransform} from "@angular/core";
@Pipe({
name: "duration",
})
export class DurationPipe implements PipeTransform {
public transform(value: any, args?: any): any {
// secs to ms
value = value * 1000;
const days = Math.floor(value / 86400000);
value = value % 86400000;
const hours = Math.floor(value / 3600000);
value = value % 3600000;
const minutes = Math.floor(value / 60000);
value = value % 60000;
const seconds = Math.floor(value / 1000);
return (days ? days + " days " : "") +
(hours ? hours + " hours " : "") +
(minutes ? minutes + " minutes " : "") +
(seconds ? seconds + " seconds " : "") +
(!days && !hours && !minutes && !seconds ? 0 : "");
}
}
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
使用moment-duration-format。
客户端框架(例如:React)
import moment from 'moment';
import momentDurationFormatSetup from 'moment-duration-format';
momentDurationFormatSetup(moment);
const breakLengthInMinutes = moment.duration(breakLengthInSeconds, 's').format('m');
服务器(node . js)
const moment = require("moment-timezone");
const momentDurationFormatSetup = require("moment-duration-format");
momentDurationFormatSetup(moment);
const breakLengthInMinutes = moment.duration(breakLengthInSeconds, 's').format('m');
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
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>
