Anyone has a link to Rails (2.3.8) RJS Api?

Do any of you 开发者_JAVA百科know any good reference for the RJS mechanisms in Rails (2.3.8)? I can find a few examples from like 2006/2007 and no actual documentation.

The API for Rails 2.3.8 is available at http://api.rubyonrails.org/v2.3.8/

Specifically for RJS, the documenation is here.
