This document describes dajaxproject.com, which provides two Django libraries - django-dajaxice and django-dajax - for asynchronous JavaScript and XML (AJAX) functionality. Django-dajaxice handles core communication between the client and server, while django-dajax allows manipulating the DOM directly from Python code. Examples are given demonstrating basic usage of making asynchronous function calls and updating the DOM via Python functions.
