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 : "");
  }
}

我的解决方案不涉及任何其他库，它与diff > 24小时工作

var momentInSeconds = moment.duration(n,'seconds')
console.log(("0" + Math.floor(momentInSeconds.asHours())).slice(-2) + ':' + ("0" + momentInSeconds.minutes()).slice(-2) + ':' + ("0" + momentInSeconds.seconds()).slice(-2))

var diff = moment(end).unix() - moment(start).unix();
moment.utc(moment.duration(diff).asMilliseconds()).format("HH:mm:ss.SSS");

这可以用于将前两个字符作为小时，最后两个字符作为分钟。同样的逻辑也适用于秒。
