如果必须显示所有的小时(超过24小时)，如果小时之前的'0'是不必要的，那么格式化可以用一小行代码完成:

Math.floor(duration.as('h')) + moment.utc(duration.as('ms')).format(':mm:ss')

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

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:

将持续时间转换为ms，然后转换为moment:

moment.utc(duration.as('milliseconds')).format('HH:mm:ss')

使用这个插件Moment Duration Format。

例子:

moment.duration(123, "minutes").format("h:mm");

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
