i need save value of variable in javascript declared , assigned value during previous call function in javascript. both declaring , initializing variable once, need value of variable when needed. there way store value of variable , retrieve it, time needed??

p1.jsp

<table>      <%         for(i=0;i<g;i++){            request.getsession().setattribute("incr",i);      %>      <tr><td><jsp:include page="/p2.jsp" /></tr></td>      <%}%> </table> 

p2.jsp

 <%!int i;%>     <%       i=request.getsession().getattribute("incr");     %>     <script type='text/javascript'>     var k<%=i%>;     function d(){          k<%=i%>=5;     }     </script>
