Jake’s Amazing Tabbed Content System

Edit 2: I’ve posted version 3 now. It’s better.

Edit: I’ve replaced the code below with Version 2. Now includes removable/re-addable tabs, nicer styling, uses one array rather than two.
Still to do: Make it write the tabs out from an array. Either that or integrate it with PHP so you only have to write the content once (in one place) and it will do the rest.

This was inspired by the tabs in phpMyAdmin which look pretty good but require a page load on when you change tabs. This makes sense in phpmyadmin (because it reloads datasets etc and keeps things up to date), but I thought it would be nice to have a smaller scale system. It should work well for multipart forms, sections of a small website, etc. I wouldn’t recommend it for large amounts of content but then again I haven’t tested that out and it seems to work quite swiftly as it is, so give it a shot and let me know.

Well, that was easier than I thought. It’s pretty basic, but you get the idea. Any ideas/comments/suggestions welcome.
