Dangers of remote Javascript. Perl.com got hit by a JavaScript porn redirect when the domain of one of their advertisers expired and was bought by a porn company. Nat Torkington suggests keeping track of the expiration dates on any third party domains that are serving JavaScript on your site. # 20th January 2008, 9:49 am

Automate firing of onload events. Paul Irish suggests setting up your site’s onload handlers in a single external JavaScript file then executing different handlers depending on the body element’s id attribute. # 17th January 2008, 4:08 pm

.first() and .last() methods for jQuery. I got fed up of expecting these to exist, so I wrote them as a couple of one-liner plugins. # 16th January 2008, 9:41 pm

jQuery 1.2.2: 2nd Birthday Present. The API stays the same, but there are some healthy speed improvements, a new way of adding custom events and (most importantly) .ready() now waits for the CSS to be ready in addition to the DOM. # 15th January 2008, 8:59 am

Javascript CSS Selector Engine Timeline. It’s not every day you see a piece of code you wrote compared to a Ford Pinto :) # 14th January 2008, 1:25 pm

Cross-Site XMLHttpRequest (via) “Firefox 3 implements the W3C Access Control working draft, which gives you the ability to do XMLHttpRequests to other web sites”—you can mark a document as available for cross-domain requests using either an Access-Control HTTP header or an XML processing instruction. # 9th January 2008, 11:57 pm

$.comet (via) The first Comet (with Bayeux) plugin I’ve seen for jQuery—currently only handles long-polling over XMLHttpRequest, but still a promising start. # 9th January 2008, 8:31 am

Why we switched to Jetty. Zimbra (recently acquired by Yahoo!) are using Jetty for Comet. It sounds like they are using Bayeux as well. # 8th January 2008, 5:12 am

20,000 Reasons Why Comet Scales. Greg Wilkins coaxes Jetty and Bayeux in to supporting 20,000 simultaneous users per server while maintaining sub-second latency, using Amazon EC2 to run the benchmark. # 7th January 2008, 8:32 am

IE7.js version 2.0 (beta). Dean Edwards has updated IE7, shifting enhancements that weren’t fixed by the real IE7 in to a new script called IE8. You can also now hotlink the library directly from Google’s servers, though I don’t know how intended Google Code’s subversion repository is for that purpose. # 6th January 2008, 11:15 pm

EditArea. Impressive JavaScript source code editor, with syntax highlighting, brace matching, search and replace and more. # 1st January 2008, 12:09 pm
