Converting milliseconds to minutes and seconds with Javascript

Question

Soundcloud s API gives the duration of it s tracks as milliseconds  JSON looks like this    duration   298999   I ve tried many functions I found on here to no avail  I m just looking for something to convert that number to something like looks like this   4 59   Here s one that got close  but doesn t work  It doesn t stop the seconds at 60  It goes all the way to 99 which makes no sense  Try entering  187810  as a value of ms  for example   var ms   298999  min   Math floor  ms 1000 60   lt  lt  0   sec   Math floor  ms 1000    60    console log min         sec     Thanks for your help   If you could add in support for hours  too  I would be grateful

Event though  oment js does not provide such functionality  if you come here and you are already using moment js  try this   function formatDuration ms      var duration   moment duration ms     return Math floor duration asHours      moment utc duration asMilliseconds    format   mm ss        You will get something like x xx xx    In the case you may want to skip the hour  when the duration is only  lt  60minutes   function formatDuration ms      var duration   moment duration ms     if  duration asHours    gt  1        return Math floor duration asHours      moment utc duration asMilliseconds    format   mm ss        else       return moment utc duration asMilliseconds    format  mm ss            This workaround in moment was introduced in this Issue

There is probably a better way to do this  but it gets the job done   var ms   298999  var min   ms   1000   60  var r   min   1  var sec   Math floor r   60   if  sec  lt  10        sec    0  sec    min   Math floor min   console log min     sec     Not sure why you have the  lt  lt  operator in your minutes line  I don t think it s needed just floor the minutes before you display   Getting the remainder of the minutes with   gives you the percentage of seconds elapsed in that minute  so multiplying it by 60 gives you the amount of seconds and flooring it makes it more fit for display although you could also get sub-second precision if you want   If seconds are less than 10 you want to display them with a leading zero

Here s my contribution if looking for      h mm ss   instead like I was   function msConversion millis      let sec   Math floor millis   1000     let hrs   Math floor sec   3600     sec -  hrs   3600    let min   Math floor sec   60     sec -  min   60     sec        sec    sec     00    sec  substring sec length      if  hrs  gt  0        min        min      min     00    min  substring min length       return hrs         min         sec        else       return min         sec

To convert any number in milliseconds to seconds just multiply it by 1000 and you solved  Or you can create function to do that and i think that s the correct way    convert milliseconds to seconds function msToSeconds number        return number   number   1000      Remember Single responsibility so do not a function like this msToSMHD

With hours  0-padding minutes and seconds  var ms   298999  var d   new Date 1000 Math round ms 1000       round to nearest second function pad i    return   0  i  slice -2     var str   d getUTCHours           pad d getUTCMinutes            pad d getUTCSeconds     console log str      0 04 59

this code will do a better job if you want to show hours  and centiseconds or miliseconds after seconds like 1 02 32 21 and if used in a cell phone the timer will show correct timing even after screen lock    x000D   x000D   lt div id  timer  style  font-family monospace   gt 00 00 lt small gt  00 lt  small gt  lt  div gt  x000D   x000D   lt script gt  x000D  var d   new Date    x000D  var n   d getTime    x000D  var startTime   n  x000D   x000D  var tm 0  x000D  function updateTimer    x000D    d   new Date    x000D    n   d getTime    x000D    var currentTime   n    x000D    tm    currentTime-startTime   x000D     x000D      tm   1   x000D       si el timer cuenta en centesimas de segundo x000D      tm   tm 10  x000D     x000D    var hours   Math floor tm   1000   60   60   x000D    var minutes   Math floor tm   60000    60  x000D    var seconds      tm   1000    60   x000D       saca los decimales ej 2 d 0 2  x000D    var seconds   seconds toString   match   -  d       d 0 -1      0   x000D    var miliseconds     00    tm  slice -3   x000D    var centiseconds  x000D   x000D     x000D       si el timer cuenta en centesimas de segundo x000D      tm   tm 10  x000D   x000D   x000D    centiseconds   miliseconds 10  x000D    centiseconds    centiseconds  toString   match   -  d       d 0 -1      0   x000D   x000D    minutes    minutes  lt  10    0          minutes  x000D    seconds    seconds  lt  10    0          seconds  x000D    centiseconds    centiseconds  lt  10    0          centiseconds  x000D    hours   hours    hours  gt  0              x000D    if  hours  0   x000D      hours     x000D      x000D   x000D    document getElementById  timer   innerHTML   hours   minutes         seconds     lt small gt      centiseconds     lt  small gt    x000D    x000D   x000D  var timerInterval   setInterval updateTimer  10   x000D     clearInterval timerInterval   x000D   lt  script gt  x000D   x000D   x000D

const Minutes     123456 60000  toFixed 2   replace              Result   2 06  We divide the number in milliseconds  123456  by 60000 to give us the same number in minutes  which here would be 2 0576  toFixed 2  - Rounds the number to nearest two decimal places  which in this example gives an answer of 2 06  You then use replace to swap the period for a colon

Best is this   function msToTime duration    var milliseconds   parseInt  duration 1000         seconds   parseInt  duration 1000  60        minutes   parseInt  duration  1000 60   60        hours   parseInt  duration  1000 60 60   24    hours    hours  lt  10     0    hours   hours  minutes    minutes  lt  10     0    minutes   minutes  seconds    seconds  lt  10     0    seconds   seconds   return hours         minutes         seconds         milliseconds      It will return 00 04 21 223  You can format this string then as you wish
