Hi, I've written a small plugin that modifies jQuery to fire events when attributes, and data items are modified. There is a better description of it on the wiki at github: http://wiki.github.com/jollytoad/jquery.mutation-events My intention is to use this as the basis for an MVC pattern, where the Model is the DOM or a DOM-like structure that jQuery can manipulate, I've discussed this further here: http://www.adaptavist.com/display/~mgibson/2009/04/28/Musings+on+MVC+in+jQuery I'd be interested to get some feedback, thoughts, ideas, etc. and if anyone is interested in joining the project.
