Simone Chiaretta post an intresting article about managing ASP.NET validation from Javascript with jQuery. Here's the small excerpt from this article:

«Validators are a great part of the ASP.NET framework: they provide a standardized and easy way to add validation to form fields. But even if the framework provides different kinds of validators, there are so many different validations patterns that sometimes you have to write custom code to match your specific requirements.

The authors of nihil logic blog publish a new plugin for jQuery library that allows to work with EXIF data from a images . Here's the small examples of using this plugin:

HTML

<img src="image1.jpg" id="img1" exif="true" />
<img src="image2.jpg" id="img2" exif="true" />
<img src="image3.jpg" id="img3" exif="true" />

JavaScript

$("#img1").click(function() {
alert("Taken with a " + $(this).exif("Make") + " " + $(this).exif("Model") + " on " + $(this).exif("DateTimeOriginal"));
// exif(strTagName) returns a string with value for the tag [strTagName]
});

$("#img2").click(function() {
alert($(this).exifPretty());
// exifPretty() returns a string with all tags and values, one tag per line
});

$("#img3").click(function() {
alert($(this).exifAll());
/* exifAll() returns an object holding all tags and their values
* {
* "Make" : "NIKON",
* "Model" : "D100",
* ...
* }
*/
});

One ofthe readers of the CSS Guy blog ask the author how to to switch the "on" state of navigation links for dynamic pages. Author gave a very detailed answer in his new post.. He writes the following:

«What Prasun is describing, just by itself, is the behavior of a set of radio buttons. You click one, and it takes on the selected state. Then you click on another one, and the new one now becomes selected, while the previous one returns to an unselected state.

But radio buttons are form elements, not navigational elements, and upon clarifying with Prasun, it's navigation that we're after.

This is the fundamental behavior of a site that uses ajax for navigation or tabs, where each "page" is created by loading new content into the content section of the current page.

This is a relatively easy way to get your feet wet with DOM scripting. So I'll first show how to do it with some very basic JavaScript functions. Also, I'll show how to do it with jQuery.

jQuery developers team release the last beta before 1.5 release.Here's the small excerpt from the official announcment:

«The third and last beta has finally arrived to jQuery UI 1.5. Hundreds of hours went into fixing more than 50 bugs for this release - it’s all about stability. jQuery UI 1.5b4 is the last release before pushing out a release candidate - and with only 5 major bugs left, you can expect to see the next release in the next couple of days!

Although it’s mainly a stability release, we also introduced many new API helpers, removed the dimensions dependancy and made all plugins a bit smaller by introducing a generic widget factory into the core. Even better, performance of UI components firing events (i.e. “mousemove” in Draggables) was dramatically improved with recent changes in the jQuery core.»

Olicer Steel tells about new plugin for jQuery librari that allows to to profile the JavaScript code. He write the following:

«Yesterday I was profiling a page that used jQuery. The page took a long time to initialize. Firebug Profile (a great tool) told me that the time was in jQuery, but that wasn’t much help — the page initialization code had a lot of calls to jQuery, to bind functions to various page elements, and most of them were harmless.»

MooSwitch is a iPhone / Time Machine style switch or toggle button for MooTools 1.2b, which you initiate this way:
var mySwitch = new mooSwitch('radioset');

Where radioset is a the name of a pair of input's with their corresponding label's.

There are three ways of toggleing, you can drag the handle to a side, click the label, or if the labels are placed outside, clicking the scroll area (the handle background). MooSwitch takes care of hiding the Radio inputs and their labels tags if they have.
