Class name not parsing correctly

Question

I have a function that finds the class name fc-id## which could be ex: fc-id3 or fc-id14

I turn this into fc-day##. The problem is it something like fc-id14 becomes fc-day1 ... It seems only the first digit is parsed...

$(mondays).each(function () {
    var num = this.className.split(' ')[0].match(/fc-id(\d)/)[1];
    var clsnme = '.fc-day' + num;

    $(this).addClass('monday');
    $(clsnme).addClass('monday');
});

How can I get it to parse the entire number?

you are using the wrong regex, use /fc-id(\d+)/ or /fc-id(\d*)/, first checks one or more digit while second checks 0 or more. Decide which one to use — vdua

var num = this.className.split(' ')[0].replace('fc-id',''); do you really need a regular expression for this ? — adeneo

It's giving you exactly what you're asking for. \d matches a single digit. If you want to match multiple digits, you need to use a quantifier like * (zero or more) or + (one or more):

/fc-id(\d+)/

Match more than one number (\d):

var num = this.className.split(' ')[0].match(/fc-id(\d+)/)[1];

\d matches for exactly one digit, \d+ matches one or more digits.
