Convert ISO 8601 time format into normal time duration

Question

I have a duration string \"PT1M33S\". I would like to get result in the following format -> 01:33 Can anyone please tell me how to do so using js or jquery??

Answer 1

I liked this answer as it was simple, however, it yields strange results if the minutes or seconds are less than 10, for example, 10:04 is returned as 10:4.

So I added some simple functions to further parse and re-assemble the time string:

function formatTimeSeg(segment) {
    newSegment = segment;
    segLength = segment.length;
    if(segLength==1){
        newSegment = '0'+segment;
    }
return newSegment;
}
extractedTime = duration.replace("PT","").replace("H",":").replace("M",":").replace("S","")
extractedTime = extractedTime.split(':');
timeLength = extractedTime.length;
switch(timeLength) {
    case 3:
        hours=extractedTime[0];minutes=extractedTime[1];seconds=extractedTime[2];
        minutes = formatTimeSeg(minutes);
        seconds = formatTimeSeg(seconds);
        formattedTime = hours+':'+minutes+':'+seconds;
    break;
    case 2:
        minutes=extractedTime[0];seconds=extractedTime[1];
        minutes = formatTimeSeg(minutes);
        seconds = formatTimeSeg(seconds);
        formattedTime = minutes+':'+seconds;
    break;
    case 1:
        seconds=extractedTime[0];
        seconds = formatTimeSeg(seconds);
        formattedTime = '0:'+seconds;
    break
}
