Javascript show milliseconds as days:hours:mins without seconds

Something like this?

function dhm(t){
    var cd = 24 * 60 * 60 * 1000,
        ch = 60 * 60 * 1000,
        d = Math.floor(t / cd),
        h = Math.floor( (t - d * cd) / ch),
        m = Math.round( (t - d * cd - h * ch) / 60000),
        pad = function(n){ return n < 10 ? '0' + n : n; };
  if( m === 60 ){
    h++;
    m = 0;
  }
  if( h === 24 ){
    d++;
    h = 0;
  }
  return [d, pad(h), pad(m)].join(':');
}

console.log( dhm( 3 * 24 * 60 * 60 * 1000 ) );

Dont know why but the others didn't worked for me so here is mine

function dhm (ms) {
  const days = Math.floor(ms / (24*60*60*1000));
  const daysms = ms % (24*60*60*1000);
  const hours = Math.floor(daysms / (60*60*1000));
  const hoursms = ms % (60*60*1000);
  const minutes = Math.floor(hoursms / (60*1000));
  const minutesms = ms % (60*1000);
  const sec = Math.floor(minutesms / 1000);
  return days + ":" + hours + ":" + minutes + ":" + sec;
}

Sounds like a job for Moment.js.

var diff = new moment.duration(ms);
diff.asDays();     // # of days in the duration
diff.asHours();    // # of hours in the duration
diff.asMinutes();  // # of minutes in the duration

There are a ton of other ways to format durations in MomentJS. The docs are very comprehensive.

Here you go:

Or if you don't want to play with a running example, then:

window.minutesPerDay = 60 * 24;

function pad(number) {
    var result = "" + number;
    if (result.length < 2) {
        result = "0" + result;
    }

    return result;
}

function millisToDaysHoursMinutes(millis) {
    var seconds = millis / 1000;
    var totalMinutes = seconds / 60;

    var days = totalMinutes / minutesPerDay;
    totalMinutes -= minutesPerDay * days;
    var hours = totalMinutes / 60;
    totalMinutes -= hours * 60; 

    return days + "." + pad(hours) + "." + pad(totalMinutes);
}
