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.
Then you can check out Load while scrolling. When we are scrolling down a webpage, the code recognizes that you are at the bottom and auto-loads new content. It helps increasing the initial load speeds of pages faster and users will have to load only the content they see.
