javascript - Format yyymmdd date

Question

I need this javascript function to not split a yyyy-mm-dd but split a yyymmdd. Current date formats are 2011-11-02 but this function needs to work with 20111102.

Script:

        function evaluateEventDate(eventdate, date){
        var eventdate = eventdate.split('-');
        var date = date.split('-');

        if (eventdate[0] === 'yyyy')
        {
            eventdate[0] = date[0];
        }

        if (eventdate[1] === 'mm') 
        {
            eventdate[1] = date[1];
        }

        if (eventdate[2] === 'dd')
        {
            eventdate[2] = date[2];
        }

        return eventdate[0]+'-'+eventdate[1]+'-'+eventdate[2];
    };

Answer 1

You could do this:

var date = date.match(/(d{4})(d{2})(d{2})/); // [yyyymmdd, yyyy, mm, dd]
date.shift(); // remove yyyymmdd from array.
