// 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

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");
}

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>

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);

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

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
