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!

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;
}

我的特定用例的最佳场景是:
var duration = moment.duration("09:30"),
formatted = moment.utc(duration.asMilliseconds()).format("HH:mm");
这改进了@Wilson的回答，因为它不访问私有内部属性_data。
如果你使用angular，添加这个到你的过滤器:
.filter('durationFormat', function () {
return function (value) {
var days = Math.floor(value/86400000);
value = value%86400000;
var hours = Math.floor(value/3600000);
value = value%3600000;
var minutes = Math.floor(value/60000);
value = value%60000;
var seconds = Math.floor(value/1000);
return (days? days + ' days ': '') + (hours? hours + ' hours ': '') + (minutes? minutes + ' minutes ': '') + (seconds? seconds + ' seconds ': '')
}
})
使用的例子
<div> {{diff | durationFormat}} </div>
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
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
将持续时间转换为ms，然后转换为moment:
moment.utc(duration.as('milliseconds')).format('HH:mm:ss')
