Suprotim Agarwal post a new article about ASP.NET aaand jQuery in which he shows how ton check or uncheck all checkboxes with jQuery. He writes:

The CheckBoxList control in ASP.NET provides a group of checkboxes that can be dynamically generated by binding it to a data source. A few months ago, I had written a similar article using ASP.NET and JavaScript over here Check/Uncheck all items in a CheckBoxList using ASP.NET and Javascript . The approach we had taken using JavaScript was, we first retrieved the checkboxlist control using document.getElementById(cbControl) and then counted the number of <input /> tags inside that control. Once we got the count, we used a loop to set the state of each control.

John Resig post an article about genetic A/B testing realization on JavaScript. He writes:

I've long been interested in the concept of A/B testing (Also called split testing). It's a simple concept that should sit will with most mathematically-inclined types: You have a baseline interface in which you adjust a single variable, at random, for each user that visits your application. After a given amount of time you should be able to see if certain variables affect how your users behave (either negatively or positively).

John Resig exploring the insertAdjancedHTML method included in Internet Explorer and Opera browsers. He writes:

While looking for improvements to injecting HTML fragments into a document (which I mentioned, in passing, when I looked at using Document Fragments) I decided to spend some more time with Internet Explorer's insertAdjacentHTML method.

This method has been in Internet Explorer since version 4.0 - as well as is in the current release of Opera - and allows you to inject fragments of well-formed HTML into a variety of locations in a document.

There is an interesting article on Jamp Mark Web creation site about creating nice dynamic text gloss effect . Here' short excerpt from beginning of this article:

The script dynamically applies Css Text Gloss Effect by Cris Yap of BestWebBuzz.com, by manipulating HTML DOM to insert a and css styles into every target element that contains the text to gloss up such as H1, H2, H3, H4, etc.

Optionally, you can set the background color of the to be consistent with your text background. By default, the script sets it from the target element if available. Otherwise, the script assumes white background color.

John Resig tells about the new real-time editor - EtherPad. He writes:

I had the opportunity, last year, to talk with the team behind AppJet. They're building something quite cool: A simple platform for developing reusable server-side applications written completely in JavaScript.

They've come a long way since I originally wrote about them late last year. They now even provide a copy of their server-side software along with the full source. This, together with Aptana's Jaxer, means that there is, at least, two high-powered, Open Source, JavaScript server platforms.

Pad is something new altogether. Building upon their existing platform, and adding in Comet streaming, they've constructed a completely real-time, multi-user, text and JavaScript editor.

There is an interesting article about converting JavaScript code from Prototype to jQuery. Here's small excerpt from this article:

Let me start off by saying I absolutely love Prototype. When a friend showed me how much it helped with writing cross-browser compatible code, I was an instant fan.

Over the years of being a Prototype user I paid close attention to the many posts about why X is a better framework than Y. I had always planned on at least TRYING another framework at some point to see what all the fuss was about.

John Resig writes about creating applications fo IPhone wwith JavaScript. Here's small excerpt from this article

I've been watching, with interest, developers create new applications for the iPhone. Owning one myself - and being knowledgeable in JavaScript - I've been wondering what options there were for creating downloadable JavaScript applications or the iPhone. In doing some research I found a number of solutions, some simpler than others, some requiring more knowledge of Objective-C than others.

Michael Mahemoff has created JavaScript library for generating GUIDs. He writes

Guid0 is a GUID library for Javascript. Okay, it doesn't yet do official, bona fide, 128-bit, GUIDs yet, mainly for API design reasons. But this is a library you might find useful if you want to generate a unique ID in your Ajax app.

There is an interesting article about creating interfaces  with jQuery UI Draggablles and Droppables on Dev102 site. Here's short excerpt from it:

I’ve just taken a look at how a rich interface for creating invitations could be created with jQuery UI’s draggables and resizables.

The goal here is to allow two basic elements to be dragged and resized in a work area to which they are limited, texts and images. They are not to be allowed to be dragged or scaled outside of the work area.

Ty Anderson post an article in which he tells about two new technologies from Microsoft—ADO.NET Entity Framework and ADO.NET Data Services. He writes:

The recent release of the Microsoft® .NET Framework® 3.5 Service Pack 1 delivered two new technologies that can positively affect how you work with data: The ADO.NET® Entity Framework and ADO.NET Data Services. Since Microsoft doesn't typically release new technologies in a service pack, you might not have heard much about them. This article will introduce you to them and provide you with insights regarding when to use them and why.

Riccardo Govoni post an article in which he  give a full overview of Javascript language. Here's short6 excerpt from this article:

Characterized by some dubious design decisions, ambiguous syntax rules, and a troubled history (see Sidebar 1. A Brief History of Why JavaScript Makes Sense), JavaScript could have been dismissed as a second-class scripting language useful only for animating web pages. However, JavaScript has matured into one of the most ubiquitous and pervasive programming languages today, currently powering complex and highly interactive web applications. With JavaScript so widely distributed and so closely tied to the user experience, JavaScript skills are mandatory if you develop web applications nowadays
