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

Python

It works by parsing the input string 1 character at a time, if the character is numerical it simply adds it (string add, not mathematical add) to the current value being parsed. If it is one of 'wdhms' the current value is assigned to the appropriate variable (week, day, hour, minute, second), and value is then reset ready to take the next value. Finally it sum the number of seconds from the 5 parsed values.

def ytDurationToSeconds(duration): #eg P1W2DT6H21M32S
    week = 0
    day  = 0
    hour = 0
    min  = 0
    sec  = 0

    duration = duration.lower()

    value = ''
    for c in duration:
        if c.isdigit():
            value += c
            continue

        elif c == 'p':
            pass
        elif c == 't':
            pass
        elif c == 'w':
            week = int(value) * 604800
        elif c == 'd':
            day = int(value)  * 86400
        elif c == 'h':
            hour = int(value) * 3600
        elif c == 'm':
            min = int(value)  * 60
        elif c == 's':
            sec = int(value)

        value = ''

    return week + day + hour + min + sec
