I could indeed get my JS to work by accessing the page directly outside of AJAX. Bob's suggestion got me thinking though, and I tried removing the $(document).ready that was wrapping my JS and suddenly everything worked! So it WAS pulling in the scripts from the page I AJAX'ed in, but it wasn't activating the ready event so nothing was happening.
Then I added Bob's code snippet to the AJAX'ed page's script and its CalendarField started working. Everything looks good! Thanks a lot for the help, you two! --Jacob Wills
