Javascript is ideal for trapping the browser events and when combined  
with rails, it works quite nicely.

You do not want to use Javascript because of limitations on your  
client browser? or because you do not want to write Javascript  
yourself?

If the latter, with rails, there are helpers that allow you to do this  
easily withing your rails code.
