Dan Webb and Luke Redpath have release the latest version of their Unobtrusive Javascript Plugin for Rails. It solves several of the main problems people run into when working with unobtrusive javascript:
UJS attempts to solve this by taking defined behaviors in the view and creating a tailored javascript file for it. Smart conditional GET and page caching techniques can be used to save bandwidth and time.
All in all, it looks like Dan and Luke did an excellent job on the plugin. Anyone using it? How’s it working out for everyone?
