I did take the first steps in switching to jQuery by using jRails, but now I'm trying to "do the right thing" and start moving this app away from the obtrusive JS and those helpers. I've been using remote_function for a long time, but using the conversion here as a model for how to move behaviors to the application.js and away from the views themselves.
So, if someone can answer the question 2 posts back about how to generate/pass the params that should help me "get it" as far as how to set those behaviors up. The conceptual prob I'm having is that the way I've been doing it seems to have a tighter coupling betw the obj being displayed and the need in some cases (like this one) to pass info about that obj back to the controller. It seems that by having the jQuery code "waiting" for an event (onChange here), it's decoupled from the view and, thus, doesnt know as much about obj's and such associated with the element it's responding on. So, my question remains... how to pass/access relevant values for the behavioral response?
