   {   
       varoffset,cookieValue;
       varsearch=name+"=";
       if(document.cookie.length>0)
       {
           offset=document.cookie.indexOf(search);
           if(offset!=-1)
           {
               offset+=search.length;  
               end=document.cookie.indexOf(";",offset);  
               if(end==-1)
                   end=document.cookie.length;  
               cookieValue=unescape(document.cookie.substring(offset,end));
           }
       }
       returncookieValue;
   }
