Jquery and quirks mode

Jquery and quirks mode

Hi

I have a page that is in quirks mode because of a wrong specified doctype. In my situation I have absolutely no chance to fix this. So I have to make my script work with this mode.

This is the script


   $(document).ready(function() {
      if ($("#Banner img[src*=testtest]").size() <= 0  &&
         $("#Banner img[src*=test]").size() <= 0)
         
         {
         
            $(".top-banner").addClass("right");
         };
         
            
   });


In quirksmode it sets the right class to the top-banner no matter what. Any suggestions to this?
