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。

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

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

var diff = moment(end).unix() - moment(start).unix();
moment.utc(moment.duration(diff).asMilliseconds()).format("HH:mm:ss.SSS");

Moment.duration (x).format()已弃用。 您可以使用moment.utc(4366589).format("HH:mm:ss")来获得所需的响应。

console.log (moment.utc (4366589) .format (HH: mm: ss)) < script src = " https://momentjs.com/downloads/moment.js " > < /脚本> < script src = " https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js " > < /脚本>

// 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);
