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')

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);

// 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

只需moment.js，不需要任何其他插件

moment().startOf('day').seconds(duration).format('HH:mm:ss')

这对我来说很管用:

moment({minutes: 150}).format('HH:mm') // 01:30

如果你使用Angular >2，我做了一个受@hai-alaluf answer启发的Pipe。

import {Pipe, PipeTransform} from "@angular/core";

@Pipe({
  name: "duration",
})

export class DurationPipe implements PipeTransform {

  public transform(value: any, args?: any): any {

    // secs to ms
    value = value * 1000;
    const days = Math.floor(value / 86400000);
    value = value % 86400000;
    const hours = Math.floor(value / 3600000);
    value = value % 3600000;
    const minutes = Math.floor(value / 60000);
    value = value % 60000;
    const seconds = Math.floor(value / 1000);
    return (days ? days + " days " : "") +
      (hours ? hours + " hours " : "") +
      (minutes ? minutes + " minutes " : "") +
      (seconds ? seconds + " seconds " : "") +
      (!days && !hours && !minutes && !seconds ? 0 : "");
  }
}
