Calling jsp with parameter - problem

Question

Hi,
i am calling another jsp in onclick event. But the parameter does seems to be passed.
when i write like below seperately,
<script type="text/javascript">
               window.location.href='emp2.jsp?empcode=<%=request.getParameter("empcode")%>&descr=<%=request.getParameter("empname")%>'
</script>
I can see emp2.jsp with correct parameters.
But when i use the above logic in onclick event, the empcode is missing.
See the onclick event.
<INPUT TYPE="submit" value="Modify" ONCLICK="window.location.href='emp2.jsp?empcode=<%=request.getParameter("empcode")%>&descr=<%=request.getParameter("empname")%>'">
Pls help where am i doing wrong.

Answer 1

Looks like it should work, provided empcode and empname are both in the request parameters when you load this page.
If you enter in the empcode and empname on the same screen as the submit button, this won't work.
I would suggest you just use the default action of a submit button, and submit a form.
This should be exactly equivalent to what you have written in your onclick event.
<form action="emp2.jsp>
<input type="hidden" name="empcode value="<%= request.getParameter("empcode") %>"
<input type="hidden" name="descr value="<%= request.getParameter("empname") %>"
<input type="submit" value="Modify">
</form>
