error if parameter present

[net1957]

on my form action i have already a locale=xx parameter.
The code add the ?X-Progress-ID=. But this is only correct for the first parameter.
So I did code a little hack :

      /* patch the form-action tag to include the progress-id if X-Progress-ID has been already added just replace it */

      if(old_id = /X-Progress-ID=([^&]+)/.exec($(this).attr("action"))) {
        var action = $(this).attr("action").replace(old_id[1], uuid);
        $(this).attr("action", action);
      } else {
        if($(this).attr("action").indexOf("?") != -1) {
          $(this).attr("action", jQuery(this).attr("action") + "&X-Progress-ID=" + uuid);
        } else {
          $(this).attr("action", jQuery(this).attr("action") + "?X-Progress-ID=" + uuid);
        }
      }

I'm not a javascript coder so I think it's not the best way, but it work.

Cheers!
