Parse classname for number at end?

Question

I have elements. I know for sure they will have a class 'fc-id#' where '#' is a number.

I need to somehow get that number. This will always be the first class of the element.

Is there some way to get the number at the end?

Thanks

What have you tried? Look at http://stackoverflow.com/questions/190253/jquery-selector-regular-expressions for a start. — sachleen, Mar 13 '13 at 18:10
Like: `var cls = element.className.split(' ')[0]; var num = cls.match(/fc-id(\d)/)[1];`? — Chad, Mar 13 '13 at 18:12

$("[class^=fc-id]").each(function(){
      var num = this.className.split(' ')[0].match(/fc-id(\d)/)[1];
});

use .split() method like

var idNum = $(this).attr('class').split('id')[1]; // #

or if you need to retrieve the first class do like:

var idNum = $(this).attr('class').split(' ')[0].split('id')[1]; // #

$("[class^=fc-id]").each(function(){
    // Everything after the first 5 characters (fc-id)
    alert($(this).attr("class").substring(5)); 
})

If the element has multiple classes, this will return the rest of them as well. – Barmar Mar 13 '13 at 18:25
