Finally I made the function to take the select name as an optional variable 
and used different names for the two. This helped me in other situations 
also. Thanks a lot.

Use different variable names.  Or make your function return a value, and use 
assignment to handle it.

In short, no.

The flow is like this:

Browser requests page.
Webserver serves page, after parsing (if needed).
Browser displays page to user, and essentially disconnects from webserver.
User fills in form.  Server has no clue as of yet.
User presses submit.  Browser connects to server and sends data.  Server now 
knows about the data.
