Client side script and resetting dropdown lists

[AB]

I am creating a ASP.Net 1.1 (VB) web. I have 2 drop down lists which
are independent of each other. Both are filled from a database on the
pageload. There is also a search button which searches the database
based on the 2 drop down list entries. The first entry in each drop
down list is "Please Select". What I am trying to do via client side
script is to reset the unselected drop down list when the other drop
down list selects a new option. All controls are ASP controls.
The reason for not posting back to the server and to reset the drop
down lists is due to the time it takes and then the end user has to do
it all again on the search option. I would prefer not to use Ajax for
this too. I would prefer javascript due to cross platform ease. I am a
newbie when it comes to java - so be gentle!!
Thanks

Which is the "unselected drop down?" And how are they independent if
one controls the other? Surely they don't each do this as that would
send the user in circles. I assume one select (what you refer to as a
"drop down list") controls the other. I also assume that by "reset"
you mean re-populate with new options.

If I (partially) understand the problem, you don't need Ajax for this.

Despite the name, JavaScript has nothing to do with Java.
