Mini-plugin for selecting elements with regex instead of an actual class name

jQuery findClassWithRegex

$.fn.findClassWithRegex = function(regex) {
  
  var results = [];

  $(this).each(function(){
    
    if ($(this).attr('class').length>0 && $(this).attr('class').match(regex)) {
      results.push( this );
    }
    
  });
  
  return results;

};

Possibly better implementation:

$.expr[':'].classmatch = function(object,i,attrs) { return !! $(object).attr('class').match(attrs[3]); };

$("#links a:classmatch(^active)");
$("#links").find("a:classmatch(^active)");

Thanks, that does look more attractive.
