How to control jsp through javascript function

[shruti]

i am writing code like this

function show(i)
{

frm.elements[0].value=i;
alert(frm.elements[0].value);
<%
String id1=request.getParameter("h1");

SetIdentity.setId(ss);
ss="again";
%>
alert("after jsp");
}

but the jsp inside <% ...%> is not running when this function show is called. its only running one time
with the program flow.
How to do so. that this code only runs when i call show function

Hi Shruti,

JSP runs server side. JavaScript runs on client side, after the response has been sent from JSP. If you view the source form the browser, you will see that the JSP tag will have gone. You will have to use other methods (like Ajax) to get data dynamically from the server.
