rails3 and unobtrusive javascript.

[Mauro]

Ok to not depend on a specific javascript framework but now its' hard
for me to reproduce the same behavior of some helpers like
observe_field.
I've found some jquery examples but all use the event change that is
triggered only when the text field loses focus.
It's not the same behavior as observe_field.
There is someone in the same situation?

Unobtrusive JavaScript and JavaScript agnosticism are really two
separate and unrelated issues.

Unobtrusive JavaScript is the "new hotness" because from a design
standpoint it makes a lot of sense. From what I can gather it seems that
most developers are trending away from the built-in helpers and doing
more with pure JavaScript.

I've not worked with Rails 3's unobtrusive JavaScript to know the issues
involved. Bu, I do use unobtrusive techniques wherever possible, which
seems to be pretty much everywhere.
