Converting Youtube Data API V3 video duration format to seconds in JavaScript/Node.js

Question

I\'m trying to convert ISO 8601 string to seconds in JS/Node. The best I could come up with was:

function convert_time(duration) {
    var a = duration.match         


        

Answer 1

I ran into issues with the above solution. I decided to write it as obtuse as possible. I also use my own "getIntValue" in place of parseInt for extra sanity.

Just thought other searching might appreciate the update.

Fiddle

    function convertYouTubeTimeFormatToSeconds(timeFormat) {

    if ( timeFormat === null || timeFormat.indexOf("PT") !== 0 ) {
        return 0;
    }

    // match the digits into an array
    // each set of digits into an item
    var digitArray      = timeFormat.match(/\d+/g);
    var totalSeconds    = 0;

    // only 1 value in array
    if (timeFormat.indexOf('H') > -1 && timeFormat.indexOf('M') == -1 && timeFormat.indexOf('S') == -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60 * 60;
    }

    else if (timeFormat.indexOf('H') == -1 && timeFormat.indexOf('M') > -1 && timeFormat.indexOf('S') == -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60;
    }

    else if (timeFormat.indexOf('H') == -1 && timeFormat.indexOf('M') == -1 && timeFormat.indexOf('S') > -1) {
        totalSeconds    += getIntValue(digitArray[0]);
    }


    // 2 values in array
    else if (timeFormat.indexOf('H') > -1 && timeFormat.indexOf('M') > -1 && timeFormat.indexOf('S') == -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60 * 60;
        totalSeconds    += getIntValue(digitArray[1]) * 60;
    }

    else if (timeFormat.indexOf('H') > -1 && timeFormat.indexOf('M') == -1 && timeFormat.indexOf('S') > -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60 * 60;
        totalSeconds    += getIntValue(digitArray[1]);
    }

    else if (timeFormat.indexOf('H') == -1 && timeFormat.indexOf('M') > -1 && timeFormat.indexOf('S') > -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60;
        totalSeconds    += getIntValue(digitArray[1]);
    }


    // all 3 values
    else if (timeFormat.indexOf('H') > -1 && timeFormat.indexOf('M') > -1 && timeFormat.indexOf('S') > -1) {
        totalSeconds    += getIntValue(digitArray[0]) * 60 * 60;
        totalSeconds    += getIntValue(digitArray[1]) * 60;
        totalSeconds    += getIntValue(digitArray[2]);
    }

//  console.log(timeFormat, totalSeconds);

    return totalSeconds;
}
function getIntValue(value) {
    if (value === null) {
        return 0;
    }

    else {

        var intValue = 0;
        try {
            intValue        = parseInt(value);
            if (isNaN(intValue)) {
                intValue    = 0;
            }
        } catch (ex) { }

        return Math.floor(intValue);
    }
}
