Plugin/Gem to get Rails 3 style UJS in Rails 2.3.x?

Question

I have a new application starting that's using Rails 2.3.8 for stability concerns and gem compatibility, however we'd like to begin being conscious of Unobtrusive JavaScript by implementing the Rails 3 style UJS in this application. Is there any existing plugin/gem that backports this feature?

We are currently using the jrails gem to swap jQuery for Prototype, as it is better suited to our needs. Is there an easy way to integrate jQuery with Rails 3 style UJS in a Rails 2.3.x application?

Answer 1

not a plugin, but still quite useful, and both solutions use jquery:
