$('.profile1,.profile3').addClass('selected')
just turn the names or numbers into vars: var selection = []; $('form checkbox:checked').each(function(){ selection.push('.'+this.whateverValue); }); // now selection == ['.profile1','.profile3']; selection = selection.join(','); $(selection).addclass('selected'); It depends on what exactly you need. - ricardo On Oct 15, 8:42 am, "Armand Datema" <[EMAIL PROTECTED]> wrote: > Hi > > I use jquery to filter a dataset based on classes.
