javascript - JavaScript で ISO 8601 期間を変換する

Question

たとえば、JavaScript で期間を変換するにはどうすればよいですか。

PT16H30M

Answer 1

"PT16H30M".replace(/PT(\d+)H(\d+)M/, "$1:$2");

Answer 2

私はちょうど1年以上の期間にわたってこれを行いました.
ここにフィドルがあります。

function convertDuration(t){ 
    //dividing period from time
    var x = t.split('T'),
        duration = '',
        time = {},
        period = {},
        //just shortcuts
        s = 'string',
        v = 'variables',
        l = 'letters',
        // store the information about ISO8601 duration format and the divided strings
        d = {
            period: {
                string: x[0].substring(1,x[0].length),
                len: 4,
                // years, months, weeks, days
                letters: ['Y', 'M', 'W', 'D'],
                variables: {}
            },
            time: {
                string: x[1],
                len: 3,
                // hours, minutes, seconds
                letters: ['H', 'M', 'S'],
                variables: {}
            }
        };
    //in case the duration is a multiple of one day
    if (!d.time.string) {
        d.time.string = '';
    }

    for (var i in d) {
        var len = d[i].len;
        for (var j = 0; j < len; j++) {
            d[i][s] = d[i][s].split(d[i][l][j]);
            if (d[i][s].length>1) {
                d[i][v][d[i][l][j]] = parseInt(d[i][s][0], 10);
                d[i][s] = d[i][s][1];
            } else {
                d[i][v][d[i][l][j]] = 0;
                d[i][s] = d[i][s][0];
            }
        }
    } 
    period = d.period.variables;
    time = d.time.variables;
    time.H +=   24 * period.D + 
                            24 * 7 * period.W +
                            24 * 7 * 4 * period.M + 
                            24 * 7 * 4 * 12 * period.Y;

    if (time.H) {
        duration = time.H + ':';
        if (time.M < 10) {
            time.M = '0' + time.M;
        }
    }

    if (time.S < 10) {
        time.S = '0' + time.S;
    }

    duration += time.M + ':' + time.S;
    alert(duration);
}
