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;
}

const duration = moment.duration(62, 'hours');
const n = 24 * 60 * 60 * 1000;
const days = Math.floor(duration / n);
const str = moment.utc(duration % n).format('H [h] mm [min] ss [s]');
console.log(`${days > 0 ? `${days} ${days == 1 ? 'day' : 'days'} ` : ''}${str}`);

打印:

2天14小时00分00秒

我的解决方案不涉及任何其他库，它与diff > 24小时工作

var momentInSeconds = moment.duration(n,'seconds')
console.log(("0" + Math.floor(momentInSeconds.asHours())).slice(-2) + ':' + ("0" + momentInSeconds.minutes()).slice(-2) + ':' + ("0" + momentInSeconds.seconds()).slice(-2))

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

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diff是一瞬间

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