rails3 and unobtrusive javascript.

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.
