Anyone...Search Results via href link?

Hi I have a Business Catalyst site and found this code here to do what I want to achieve http://www.atlantawebdesignga.com/_blog/Adobe_Business_Catalyst_Developer/post/Use_a_Link_to_Submit_A_Web_App_Search_Results_Page_in_Adobe_Business_Catalyst/:

<script type="text/javascript">
   jQuery(document).ready(function(){
   var theCategory = '{ module_url,category}' ;
   if (theCategory) {
      jQuery('form.webapp option:contains("' + theCategory + '")').attr('selected', 'selected');
      jQuery("form.webapp").submit();
  }
});
</script>

My link is formated as follows:
http://mywebsite.businesscatalyst.com/blog-search-results.html?category=Baubles

Looks just what I need to do, link to search results page with category pre selected . Auto submit the form and have results on the page for the user.
Great and it works but it keeps refreshing/bouncing on the page. Can anyone see a way to stop it submiting more than once?
Help apprectaied.

p.s Merry Christams to you all.

Regards
Lee
