When I select an option of a configurable product I want to load that specific Part Number's product tabs. I assume AJAX would be the easiest way to do this but I am unfamiliar with using AJAX. If anyone can point me in the right direction or has a different suggestion on how to accomplish this it will be much appreciated.
Starting out with AJAX in Magento might be a big leap. I'd like to suggest first starting out with familiarizing yourself with AJAX first. Some basic tutorials
When you have a good basic understanding of how AJAX works checkout subeshpokhrel's ajaxify extension to get you started on the basics of AJAX in Magento. That should point you in the right direction.
So after looking around and playing with some code I found what I wanted to do. So i wanted to load product tabs of single products on my product page and figured i would need some type of AJAX, Prototype, or jQuery solution. I experimented with AJAX.Updater Ajax.Updater API and it didn't seem to do what I wanted. Also from my understanding I would have to have a custom module in place to execute this the way I wanted. In the end I used jQuery.on() jQuery.on() API mixed with some prototype calls and jQuery calls to select the elements I needed to load and where to put them.
