使用这行代码:

moment.utc(moment.duration(4500, "seconds").asMilliseconds()).format("HH:mm:ss")

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");
}

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。

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>

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:

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
