Hi there!

Hope that this is the right place to post at.

I am trying to pass a javascript variable to another JSP through sessions.

But I am not sure of how to do it.

Thanks in advance!

Regards
Yans Tan

I'm not sure about what you mean by "through sessions".
What you could do is set the value into a hidden field before submitting.

I think you can catch the value of Java Script variable to html field and then set the value of that field in session.

Javascript variables exist on the client machine (browser).
JSP session variables exist on the server. If you want to transfer a value from the client to the server you will need to post them to the server in an HTTP request.

Hi there!

Sorry to bother you people. Thanks for the solution.

This is what I did. Not sure anything wrong with it.

<%
final HttpSession curSession = request.getSession( false );
final String selectedIndex = (String)curSession.getValue(selectedIndexKeyName);
%>

document.frmCity.selCity.selectedIndex = <%= selectedIndex %>

Thanks all!

Regards
Yans
