datetime - Hvordan konvertere tid i millisekunder til timer, minutter, sekunder-format i JavaScript?

Jeg har en tid som et antall millisekunder og jeg vil konvertere det til et HH:MM:SS-format. Det skal rulle over, med milliseconds=86400000 ønsker jeg å få 00:00:00.

Hva med å lage en funksjon som dette:

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))

For å konvertere tid i millisekunder til menneskelig lesbart format.

function msToTime(ms) {
  let seconds = (ms / 1000).toFixed(1);
  let minutes = (ms / (1000 * 60)).toFixed(1);
  let hours = (ms / (1000 * 60 * 60)).toFixed(1);
  let days = (ms / (1000 * 60 * 60 * 24)).toFixed(1);
  if (seconds < 60) return seconds + " Sec";
  else if (minutes < 60) return minutes + " Min";
  else if (hours < 24) return hours + " Hrs";
  else return days + " Days"
}

console.log(msToTime(1000))
console.log(msToTime(10000))
console.log(msToTime(300000))
console.log(msToTime(3600000))
console.log(msToTime(86400000))

Jeg hadde det samme problemet, dette er hva jeg endte opp med å gjøre:

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);

Her er min løsning

let h,m,s;
h = Math.floor(timeInMiliseconds/1000/60/60);
m = Math.floor((timeInMiliseconds/1000/60/60 - h)*60);
s = Math.floor(((timeInMiliseconds/1000/60/60 - h)*60 - m)*60);

// for å få tidsformat 00:00:00

s < 10 ? s = `0${s}`: s = `${s}`
m < 10 ? m = `0${m}`: m = `${m}`
h < 10 ? h = `0${h}`: h = `${h}`


console.log(`${s}:${m}:${h}`);

Denne returnerer tid som YouTube-videoer

    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;
    }

Utdata :

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

Beklager, sent ute til festen. Det aksepterte svaret holdt ikke for meg, så jeg skrev det selv.

Utdata :

2h 59s
1h 59m
1h
1h 59s
59m 59s
59s

Kode (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)));
