Signs of a Poorly Written jQuery Plugin
Signs of a poorly written jQuery plugin by Remy Sharp takes a very simple plugin example and then shows some common mistakes — classics like “double jQuery”, where people accidentally call $() on an existing jQuery instance.
If you’re interested in writing a jQuery plugin, you should read this and the comments. The article was posted last month, so there is some interesting discourse in the comments.
Boxes with Easing and Motion Blur
Floating Boxes with motion blur and easing by Marcell Jusztin isn’t necessarily going to be used in your next project. The reason I found it interesting is the author uses CSS 3 box-shadow and text-shadow to simulate motion blur, which I thought was a cool hack.
autoNumeric (MIT License) by Robert J Knothe makes supporting international currencies and number formats easy. This plugin makes input fields automatically display the correct formatting for a given currency — separator type and placement, currency symbol and placement, decimal places, and rounding are all handled.
I’ve run into the complexities of supporting multiple currency formats before, so this may be useful in the future.
