How to convert minutes to hours/minutes and add various time values together using jQuery?

Question

There are a couple parts to this question. I am not opposed to using a jQuery plugin if anyone knows of one that will accomplish what I want done.

Q1 - How d

Answer 1

I took the liberty of modifying ConorLuddy's answer to address both 24 hour time and 12 hour time.

function minutesToHHMM (mins, twentyFour = false) {
  let h = Math.floor(mins / 60);
  let m = mins % 60;
  m = m < 10 ? '0' + m : m;

  if (twentyFour) {
    h = h < 10 ? '0' + h : h;
    return `${h}:${m}`;
  } else {
    let a = 'am';
    if (h >= 12) a = 'pm';
    if (h > 12) h = h - 12;
    return `${h}:${m} ${a}`;
  }
}

Answer 2

function parseMinutes(x) {
  hours = Math.floor(x / 60);
  minutes = x % 60;
}

function parseHours(H, M) {
  x = M + H * 60;
}

Answer 3

In case you want to return a string in 00:00 format...

convertMinsToHrsMins: function (minutes) {
  var h = Math.floor(minutes / 60);
  var m = minutes % 60;
  h = h < 10 ? '0' + h : h;
  m = m < 10 ? '0' + m : m;
  return h + ':' + m;
}

Thanks for the up-votes. Here's a slightly tidier ES6 version :)

function convertMinsToHrsMins(mins) {
  let h = Math.floor(mins / 60);
  let m = mins % 60;
  h = h < 10 ? '0' + h : h;
  m = m < 10 ? '0' + m : m;
  return `${h}:${m}`;
}

Answer 4

This code can be used with timezone

javascript:

let minToHm = (m) => {
  let h = Math.floor(m / 60);
  h += (h < 0) ? 1 : 0;
  let m2 = Math.abs(m % 60);
  m2 = (m2 < 10) ? '0' + m2 : m2;
  return (h < 0 ? '' : '+') + h + ':' + m2;
}

console.log(minToHm(210)) // "+3:30"
console.log(minToHm(-210)) // "-3:30"
console.log(minToHm(0)) // "+0:00"

minToHm(210)
"+3:30"

minToHm(-210)
"-3:30"

minToHm(0)
"+0:00"

Answer 5

Not a jquery plugin, but the DateJS Library appears to do what you require. The Getting Started page has a number of examples.

Q1:

$(document).ready(function() {
    var totalMinutes = $('.totalMin').html();

    var hours = Math.floor(totalMinutes / 60);          
    var minutes = totalMinutes % 60;

    $('.convertedHour').html(hours);
    $('.convertedMin').html(minutes);    
});

Q2:

$(document).ready(function() {

    var minutes = 0;

    $('.min').each(function() {
        minutes = parseInt($(this).html()) + minutes;
    });

    var realmin = minutes % 60
    var hours = Math.floor(minutes / 60)

    $('.hour').each(function() {
        hours = parseInt($(this).html()) + hours;
    });


    $('.totalHour').html(hours);
    $('.totalMin').html(realmin);    

});
