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

如果你愿意使用不同的javascript库，numeric .js可以将秒格式化如下(例如1000秒):
var string = numeral(1000).format('00:00');
// '00:16:40'
将时刻持续时间格式化为字符串
var duration = moment.duration(86400000); //value in milliseconds
var hours = duration.hours();
var minutes = duration.minutes();
var seconds = duration.seconds();
var milliseconds = duration.milliseconds();
var date = moment().hours(hours).minutes(minutes).seconds(seconds).millisecond(milliseconds);
if (is12hr){
return date.format("hh:mm:ss a");
}else{
return date.format("HH:mm:ss");
}
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 : "");
}
}
var diff = moment(end).unix() - moment(start).unix();
moment.utc(moment.duration(diff).asMilliseconds()).format("HH:mm:ss.SSS");
// set up
let start = moment("2018-05-16 12:00:00"); // some random moment in time (in ms)
let end = moment("2018-05-16 12:22:00"); // some random moment after start (in ms)
let diff = end.diff(start);
// execution
let f = moment.utc(diff.asMilliseconds()).format("HH:mm:ss.SSS");
alert(f);
