Lazy loading excanvas.js

I started by developing an HTML example page that used the canvas element and had the excanvas.js file hard-coded. Everything worked as planned. I then took out the hard-coded excanvas.js file and replaced it with a JavaScript-based lazy loader. Guess what? It didn’t work. A simple modification to the excanvas.js file fixed the problem.

Custom modal windows using canvas and MooTools

I’ve built a simple modal window class named Modal using MooTools. This class combines a dynamic canvas drawing API (my Rectangle class) with dynamic DOM element generation to create on-demand modal windows using no external images. My goal was to make this about as easy to use as a normal JavaScript alert, prompt or confirm window.

Fun with canvas and MooTools: a Rectangle class

Recently at work I realized I needed a good modal window that was more extensible than JavaScript’s built-in confirm and prompt windows. MochaUI looked like a handy way to get slick modal windows into my project, but I soon realized that MochaUI is designed to do much, much more than I need, and therefore is (for my purposes) bloated. So, in typical DIY fashion here at pipwerks, I decided to borrow a page from Greg’s book and make my own MochaUI-inspired modal window using the canvas element, CSS, HTML, and MooTools. After evaluating what I’d need for my little modal window, I whipped up a MooTools-based JavaScript class that produces canvas rectangles in the blink of an eye.
