javascript - JavaScriptでミリ秒単位の時間を時間、分、秒形式に変換する方法は?

Question

ミリ秒単位の時間があり、それを形式に変換したいと考えていHH:MM:SSます。milliseconds = 86400000I want to getでラップアラウンドする必要があります00:00:00。

Answer 1

次のような関数を作成してはどうでしょうか。

function msToTime(duration) {
  var milliseconds = Math.floor((duration % 1000) / 100),
    seconds = Math.floor((duration / 1000) % 60),
    minutes = Math.floor((duration / (1000 * 60)) % 60),
    hours = Math.floor((duration / (1000 * 60 * 60)) % 24);

  hours = (hours < 10) ? "0" + hours : hours;
  minutes = (minutes < 10) ? "0" + minutes : minutes;
  seconds = (seconds < 10) ? "0" + seconds : seconds;

  return hours + ":" + minutes + ":" + seconds + "." + milliseconds;
}
console.log(msToTime(300000))

Answer 2

私は同じ問題を抱えていました、これは私がやったことです：

function parseMillisecondsIntoReadableTime(milliseconds){
  //Get hours from milliseconds
  var hours = milliseconds / (1000*60*60);
  var absoluteHours = Math.floor(hours);
  var h = absoluteHours > 9 ? absoluteHours : '0' + absoluteHours;

  //Get remainder from hours and convert to minutes
  var minutes = (hours - absoluteHours) * 60;
  var absoluteMinutes = Math.floor(minutes);
  var m = absoluteMinutes > 9 ? absoluteMinutes : '0' +  absoluteMinutes;

  //Get remainder from minutes and convert to seconds
  var seconds = (minutes - absoluteMinutes) * 60;
  var absoluteSeconds = Math.floor(seconds);
  var s = absoluteSeconds > 9 ? absoluteSeconds : '0' + absoluteSeconds;


  return h + ':' + m + ':' + s;
}


var time = parseMillisecondsIntoReadableTime(86400000);

alert(time);

Answer 3

これはYouTubeの動画のように時間を返します

    function getYoutubeLikeToDisplay(millisec) {
        var seconds = (millisec / 1000).toFixed(0);
        var minutes = Math.floor(seconds / 60);
        var hours = "";
        if (minutes > 59) {
            hours = Math.floor(minutes / 60);
            hours = (hours >= 10) ? hours : "0" + hours;
            minutes = minutes - (hours * 60);
            minutes = (minutes >= 10) ? minutes : "0" + minutes;
        }

        seconds = Math.floor(seconds % 60);
        seconds = (seconds >= 10) ? seconds : "0" + seconds;
        if (hours != "") {
            return hours + ":" + minutes + ":" + seconds;
        }
        return minutes + ":" + seconds;
    }

出力：

• getYoutubeLikeToDisplay(129900) = "2:10"
• getYoutubeLikeToDisplay(1229900) = "20:30"
• getYoutubeLikeToDisplay(21229900) = "05:53:50"

Answer 4

ごめん、パーティーに遅れて。受け入れられた答えは私にとってそれをカットしなかったので、私はそれを自分で書きました.

2h 59s
1h 59m

1h 59s

コード (Typescript):

function timeConversion(duration: number) {
  const portions: string[] = [];

  const msInHour = 1000 * 60 * 60;
  const hours = Math.trunc(duration / msInHour);
  if (hours > 0) {
    portions.push(hours + 'h');
    duration = duration - (hours * msInHour);
  }

  const msInMinute = 1000 * 60;
  const minutes = Math.trunc(duration / msInMinute);
  if (minutes > 0) {
    portions.push(minutes + 'm');
    duration = duration - (minutes * msInMinute);
  }

  const seconds = Math.trunc(duration / 1000);
  if (seconds > 0) {
    portions.push(seconds + 's');
  }

  return portions.join(' ');
}

console.log(timeConversion((60 * 60 * 1000) + (59 * 60 * 1000) + (59 * 1000)));
console.log(timeConversion((60 * 60 * 1000) + (59 * 60 * 1000)              ));
console.log(timeConversion((60 * 60 * 1000)                                 ));
console.log(timeConversion((60 * 60 * 1000)                    + (59 * 1000)));
console.log(timeConversion(                   (59 * 60 * 1000) + (59 * 1000)));
console.log(timeConversion(                                      (59 * 1000)));

Answer 5

必要な時間は 1 日、24 時間だけでした。これが私の見解です。

const milliseconds = 5680000;

const hours = `0${new Date(milliseconds).getHours() - 1}`.slice(-2);
const minutes = `0${new Date(milliseconds).getMinutes()}`.slice(-2);
const seconds = `0${new Date(milliseconds).getSeconds()}`.slice(-2);

const time = `${hours}:${minutes}:${seconds}`
console.log(time);

必要に応じて、この方法で日数を取得することもできます。

Answer 6

タイプスクリプトを使用している場合、これはあなたにとって良いことかもしれません

enum ETime {
  Seconds = 1000,
  Minutes = 60000,
  Hours = 3600000,
  SecInMin = 60,
  MinInHours = 60,
  HoursMod = 24,
  timeMin = 10,
}

interface ITime {
  millis: number
  modulo: number
}

const Times = {
  seconds: {
    millis: ETime.Seconds,
    modulo: ETime.SecInMin,
  },
  minutes: {
    millis: ETime.Minutes,
    modulo: ETime.MinInHours,
  },
  hours: {
    millis: ETime.Hours,
    modulo: ETime.HoursMod,
  },
}

const dots: string = ":"

const msToTime = (duration: number, needHours: boolean = true): string => {
  const getCorrectTime = (divider: ITime): string => {
    const timeStr: number = Math.floor(
      (duration / divider.millis) % divider.modulo,
    )

    return timeStr < ETime.timeMin ? "0" + timeStr : String(timeStr)
  }

  return (
    (needHours ? getCorrectTime(Times.hours) + dots : "") +
    getCorrectTime(Times.minutes) +
    dots +
    getCorrectTime(Times.seconds)
  )
}
