Answer My Query

Validatious is an unobtrusive JavaScript that allows you to easily add form validation. Validatious does not requires any JavaScript library; however if you’re using one, it can easily work with it. It is cross browser and has been tested to work on IE6+, Firefox 2.0+, Opera 9.5+, Safari 3.0+, Chrome.

You can use it to validate forms with semantic HTML and/or a simple JavaScript DSL. Validatious has multilingual support and easily extensible (i.e., adding custom validators) with only a couple of lines of JavaScript. Several settings allow you to control how and when Validatious does validation, how it displays errors and more. If configuring isn’t enough, callbacks and easy overriding gives you complete control.

Validatious is written by Christian Johansen. The standalone version gratefully uses Dean Edwards’  addEvent  and Base as well as addDOMLoadEvent, created by Jesse Skinner, Dean Edwards, Matthias Miller and John Resig.

Validatious is offered with a BSD License, which means you can use it for whatever you want to, however you want to. You can find further information, demo, documentation & download on Validatious Website.

Many of the web applications I help build can be classified as in-production line of business applications that receive frequent and ongoing feature enhancements. Typically, these applications have dozens if not hundreds of users who rely on the site each and every day to accomplish tasks necessary to keep the company running smoothly. Every week or so the latest code is deployed to the production servers, bringing with it bug fixes and, very often, new features or changes to existing features. One challenge I've bumped into when working on such applications is how to best alert users of the new features and the changes to existing features?

One useful way to announce any important, system-wide changes is to do so immediately after the user signs into the site. A very simple way to accomplish this would be to automatically redirect all users to an announcements page after signing in, which would list information about the most recent updates to the application. However, this approach desensitizes the user to the announcement page since they are sent there each time they sign in, regardless of whether they've already seen the announcement. A better approach is to determine if there were any announcements made since the user last signed in. If so, redirect the user to a web page that displays just those unread announcements.

This article shows how to implement such a system using ASP.NET's Membership system, the Login control, and a dash of code. A complete working demo is available for download at the end of this article. Read on to learn more!

As I mentioned in New W3C website launched, the W3C recently launched a new version of their website. One of the new (to me at least – I don’t remember seeing it on the old site) documents is the Accessibility overview in the Web Design and Applications section.

The document is a great summary of what Web accessibility is and why it is important. It also contains links to further reading, accessibility guidelines, examples, and much more.
