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!

// 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);
看看JSFiddle

使用这个插件Moment Duration Format。
例子:
moment.duration(123, "minutes").format("h:mm");
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>
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
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")
}
示例案例:
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
