Http Request Obj

Question

folks
i have an JSP application in which i have a SELECT box, based on the selected value i need to display some table
in an particular place ( using DIV to display), now if i do like below i.e calling a function in the Select Tag
this will display whatever i select,
function displayTable(tab){
document.getElementById('Table').innerHTML = tab.value;
document.getElementById('Table').style.visibility = "visible";
But i need to get that value from the Select tag and call couple of objects which internally queries the database
and i need to display at the DIV tag position,
Both should display in the same page, I mean the First one i.e Select box and the Table(after selecting )
now i tried to do this below in side the above function:-
<%
String str = request.getParameter("Table");
System.out.println("String:" + str);
%>
But i am getting String:null which is correct , but let me know how to get the value which is being passed the above function
and pass to the Java String object so that i can display a particular table
Any code piece is appreciated
Thanks
Mathew

If I am reading ur ques correctly, u r trying to access the request's getParameter without submitting the form. Try javascript instead. you can try -- document.forms[0].listbox.options[document.forms[0].listbox.selectedIndex].value to get the value from the listbox.
