Prefetching Files Using jQuery

>Since years, Gecko-based browsers have supported link prefetching, while other browsers (notably Internet Explorer) are lacking this function.

Here’s a simple JavaScript-based work-around based on jQuery:

$(document).ready(function() {

// Prefetch all files referenced in [LINK rel="prefetch" href="xyz"] tags...
var $prefetchTags = $('HEAD LINK[rel=prefetch][href]');

// ...starting with the ones that can be done asynchronously via AJAX...
$prefetchTags.filter('[href$=.txt],[href$=.js],[href$=.html]')
.each(function() {
$.ajax({url: this.href, dataType: 'text'});
});

// ...followed by all referenced images,
$prefetchTags.filter('[href$=.png],[href$=.jpg],[href$=.jpeg],[href$=.gif]')
.each(function() {
new Image().src = this.href;
});

It looks for all LINK tags in the HEAD section of the HTML document that have rel="prefetch" set.

Then it processes all HREF attributes, but treating text files and images differently, since text files can easily be downloaded using asynchronous HTTP requests (a.k.a. XMLHttpRequest or AJAX), while this method is not well-suited for fetching binary files.

This approach may be a bit rough on the edges, since I’ve only done limited testing, on Fireefox 3.0/Mac and MSIE 8.0/WinXP.

 

Reducing IE 6 Support

>It’s well known that IE 6 is causing a lot of grief for Web Developers. Recently, Digg announced they will reduce support for IE 6.

Now, Youtube is also announcing they are reducing IE 6 support. They are actively advising IE 6 users to upgrade to either IE 8, Google Chrome (of course) or Firefox 3.5.

See this image:

In my opinion, this is an excellent development. End users as well as system admins should be pushed to migrate to more standards-compliant browsers. I realize this will have a significant impact on some companies, especially with IE6-specific intranet sites.

Browser News Updates

>Some recent browser news updates:

Another thing worth noting: Peter-Paul Koch is currently testing mobile browser compatiblity, paid by Vodafone.

 

>Firefox 3.0 released – and other browser news

>

Today (June 18), Mozilla Firefox 3.0 has officially been released. YSlow (a web page performance analysis extension for Firefox, by Yahoo) has been updated to 0.9.5 beta 2, just in time to support Firefox 3.

Some other browser news:

  • Opera 9.5 has been released;
  • the Firefox 3.1 features have been defined, see the MozillaWiki and the article on MozillaLink; a first alpha release is target for mid July;
  • Microsoft announced that the 2nd beta of IE 8 is scheduled for August 2008;
  • Apple has provided an early build of Safari 4 on the Apple Developer Connection, apparently with their new JavaScript engine SquirrelFish integrated;
  • the GrApple theme (that makes Firefox look like a native Mac app) has been updated for Firefox 3.
 

>Microsoft wants to break up HTML 5

>In an interview with SDTimes, Chris Wilson, MSIE platform architect Chris Wilson proposed that HTML 5 be split into several substandards.

Sounds like a reasonable and interesting proposal, but even better is to see that Microsoft appears to join the HTML 5 bandwagon. Although reviews on MSIE 8 beta 1 have not been very positive, the overall impression is that web standards support from Redmond is improving.

>HTML and DOM Standards Compliance in IE8 Beta 1

>The Internet Explorer blog added a new and interesting article on the standards compliance improvements in MSIE 8 beta 1:

It not only elaborates on the changes in beta 1, but also notes what is planned for beta 2 and -more importantly- what is and what is not planned to be fixed in the IE 8 final release.

Note that there’s a reference to our very own (Dutch) PPK, of quirksmode.org and fronteers.nl fame.

>CSS improvements planned for MSIE 8.0 (final)

>On the Microsoft Internet Explorer blog, a new article appeared today, titled “Internet Explorer 8 Beta 1 for Developers – Standards Highlights Part 2“. This article points to a document about the various IE versions and CSS compatibility:

From the document, it becomes clear that while IE 8 beta 1 already improves CSS compatibility compared to IE 7, there are still some improvements planned before the IE 8 final release:

So there’s still something to look forward to…

I wonder how much of this will affect the IE 8 score on the Acid 3 test, but I don’t expect them to beat WebKit anytime soon (who just achieved 100/100).
