CacheFile.net: Central JavaScript Library URLs

Category: JavaScript, Library

Jon Davis has created CacheFile, a place to store versions of common libraries such as Dojo, jQuery, Ext, Prototype and more. Dojo has a nice CDN already thanks to AOL, and YUI thanks to Yahoo!

Unobtrusive JavaScript – Rules to work by

Category: Accessibility, JavaScript, Unobtrusive JS

From what I’ve seen, it appears that many developers, especially those new to the JS space are somewhat confused by the reasons for developing JS in an unobtrusive fashion. Typical arguments that I’ve heard are: It takes too long to develop If they don’t have JavasScript, then they’re out of luck We shouldn’t have to Read the rest…

JavaScript Madness: Keyboard Events

Category: JavaScript

Jan Wolter has done the ugly work of testing keyboard event handling across platforms and browses. He has a test script that you can run yourself.

Using the Yahoo Global Object to Manage Object Inheritance and Composition

Category: JavaScript, Yahoo!

The Yahoo! UI team have “posted four new examples that step through some of the most important methods in the YUI Library — particularly YAHOO.lang.extend, YAHOO.lang.augmentObject, and YAHOO.lang.augmentProto.

HTML5 Media Support: video and audio tags and scriptability

Category: HTML, JavaScript, WebKit

You can add video to a page as easily as: < View plain text > HTML <video src="sample.mov" autoplay></video> That is a lot cleaner than the mess of embed/object/JavaScript wrappers that we have today. Also, there Read the rest…
