jQuery - a couple neat items
I started working on table sorting for my rankings system and stumbled upon a very cool table sorter. Tablesorter is a jQuery plugin for turning a standard HTML table with THEAD and TBODY tags into a sortable table without page refreshes. Tablesorter can successfully parse and sort many types of data including linked data in a cell.
I've also used a similar system, on Minnesota Connect, High School, and NCAA Wrestling to manage the rankings of each category.
