How do I make a observe_field function on a select in Rails 3?
I mean, how do I get a simple basic classic html select do an ajax call?
The simplicity with a regular observe_field is gone. Everything is
obtrusive javascript these days (ever heard of external .js) which makes
simple stuff much more complex. In my eyes anyway. Inventing the wheel
all over again. In Rails 4 you will be able to program the browser via
Rails 
Solved it.
jquery seems like much more coding, more complex, than prototype. I
think I’ll stay with the latter. Comments? Pros and cons?
yes，jquery will do your mean.

Still have problem with making a basic ajax call and have a div updated.
No explaining to be found. Can jquery do this simple task?
