How to convert decimal time value to hh:mm?

jansson_17

I have a script which returns a decimal value to represent time. I need to convert the decimal time value to hh:mm (i.e: 90 minutes decimal value 1.5 should be represented as 1:30. Having trouble figuring this out. Attached is my current script.

<script>
function Convert() {
    var minutes = document.getElementById("sum").value;
    var hours = minutes / 60;
    document.getElementById('total').value = hours;
    document.getElementById('sum').value = minutes;
var convert = function (sum) {
    return Math.floor(sum/60) + ":" + (sum-Math.floor(sum/60)*60);
}


</script>

Something like this ...

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title> Untitled </title>
</head>
<body>
 <input id="HrMin" value="1.5"> Decimal Hours and Minutes <br>
 <button
 onclick="document.getElementById('HHMM').value=convertToHHMM(document.getElementById('HrMin').value)">
 Convert to HH:MM</button>
 Results <input id="HHMM" value="">

<script type="text/javascript">
// From: http://www.webdeveloper.com/forum/showthread.php?273645-How-to-convert-decimal-time-value-to-hh-mm&daysprune=30

function convertToHHMM(info) {
  var hrs = parseInt(Number(info));
  var min = Math.round((Number(info)-hrs) * 60);
  return hrs+':'+min;
}
</script>

</body>
</html>
