我使用:

var duration = moment.duration("09:30");
var str = moment(duration._data).format("HH:mm");

我在var str中得到"09:30"

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);

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:

// 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

如果你愿意使用不同的javascript库，numeric .js可以将秒格式化如下(例如1000秒):

var string = numeral(1000).format('00:00');
// '00:16:40'

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
