XMLHttpRequest in IE 7 - July 31, 2006

Michael Mahemoff at Ajaxian addresses the issue of native XMLHttpRequest support in IE 7. The IE 7 team has repeatedly stated, with relative fanfare, that the new browser will include native XMLHttpRequest. But, as Michael points out, the question remains: just how native is this native XMLHttpRequestTwo points worth mentioning are 1) xhr.prototype fails and 2) IE has an option to disable native XHR. So, when native XMLHttpRequest support in IE is being touted, remember to take it with the...

A javascript boot camp tutorial - July 28, 2006

Amy Hoy from Slash7.com gave a 3 hour tutorial on Javascript at O'Reilly OSCON 2006. Because she is such a nice person, Amy has released her 3-meg PDF and source code used in her presentation. These are excellent resources to keep handy when you need to look up a method or object. This is no skimpy wimpy PDF; it's 108 pages! Give it a quick read through because it is rather entertaining (well to me anyways). Read Permalink Email...

Add mouse wheel scrolling to your next web app - July 25, 2006

Using Javascript to utilize the scroll wheel a la Google maps is the new "cool guy" thing. I found a site that walks you through the necessary code so you can add it to your next project. What you can use it for besides scrolling in and out is beyond me. Remember, not everyone has a scroll wheel mouse, so use with caution. If you have any great uses for something like this leave a comment. I'm curious as to what other people are imagining...Read Permalink Email...

The unofficial Google paint - July 18, 2006

Google has been into office products lately with Google Spreadsheet recently launched and Writely soon to be too. But Google forgot the coolest office app of all -- MS Paint. Now, thanks to a clever Javascripter, a parody is released for our consumption. Mind you this is not an official Google product, but it sure should be. The classic MS Paint interface and functionality have been captured beautifully. Most tools don't work and pop up a confirm box stating "unimplemented. But the tools.

List incoming links with Smugpanel - July 17, 2006

Want to show off your high Google ranking Show the world who links to you with Chris Heilmann's Smugpanel. This lightweight tool displays a list of incoming links on your site, and features some cool dynamic behavior that "shuffles" the list when you click a link. Smugpanel utilizes the Yahoo Site Explorer Inbound Links API, so you'll need to register a Yahoo application ID in order to use it.

Smooth color picker using Javascript - July 16, 2006

Who says AJAX applications can't look and feel like their desktop counterparts This javascript color selector is smooth, fluid, and looks like it came straight out of a desktop graphics app. You can drag your mouse around the big color selector box, drag the slider up and down, and your results update instantly. Other attempts like ColourMod have been clunky. I've tested this in both Firefox and IE and it works perfectly.Read Permalink Email...

Create an auto-hide dock with javascript and CSS - July 13, 2006

Everybody wants to be like OSX, including Michael Whalen of Whalesalad.com. With a little creativity, Michael has created a semi-transparent dock that fades down when you mouse over the header of his website. Inside the dock he has links with darker semi-transparent rollovers. The code is fairly simple and relies on Script.aculo.us (prototype.js and effects.js) for the animations. The hardest part of this project according to Michael was getting the dock to fade away when you mouse out of the...
