Just released a YUI script which counts the amount of characters in a textarea and displays them (like a counter). When you exceed the maximum length the script will display a message. Just give it a try: YUI textarea script.

This snippet scrolls newsitems (unordered list) horizontally. On mouse-over the scrolling ticker will pause. After moving your mouse out again it will resume animating.Code and example can be found here and here. 

The focus behavior of form elements is not supported correctly in all browsers. That’s why I created this simple small script to add this functionality to all text fields in a page. It uses the YUI javascript library, but it off course can be made also for other libraries like jQuery or Prototype.

Yahoo!’s YUI team announced a preview release of their Javascript framework. This is a big release! It is lighter, faster, more consistent, more powerful and more securable. There is a change is style and structure (sandboxing, modularity, self-completing, selectors, custom events, nodes and nodelists, chaining). The first big beta release is planned to be in December 2008.

Over the last three or four years the role of Frontend Engineering has become more important, more respected, more challenging, and more in-demand than ever before, and so Nate Koechley wanted to put a stake in the ground clarifying what we do, how we do it, and why it’s so important to raise it to a professional level. See the slides of his presentation: Professional Frontend Engineering.

Everyone now knows that reducing the amount of HTTP-requests is good for the site-performance. Using CDN is a way to reduce the amount of HTTP requests from one server, which improves the performance. Now Yahoo! comes up with Combo Handler Service which alows you to call several Javascript files by just one HTTP-request.

jQuery released a new version, 1.2.6. The biggest improvement is the performance of the code. This Google spreadsheet shows the details. Also the dimension’s plugin was added to the core of jQuery. This plugin supports tracking of element dimensions, offsets and positioning. Read more in the jQuery 1.2.6 release notes.

Yahoo! released a new version of their Javascript library. Some bugs are fixed and the new version supports the upcoming releases of Firefox 3 and Opera 9.5. Download the new version.

Yahoo! BrowserPlus is software that extends the capabilities of your web browser to make richer web experiences possible. Different websites can use BrowserPlus to support things like drag and drop from the desktop, easier file uploads, more efficient and secure acquisition of feeds and information, and native desktop notifications. BrowserPlus is a technology designed to “extend the web,” so that developers can build more exciting web applications and so end-users can get more done inside their web browser.

Today you can explore BrowserPlus demo applications which include an advanced in-page Flickr photo uploader, a browser based IRC (chat) Client, and a developer tool for exploring Web Services output. Developers can also explore the BrowserPlus APIs and test code samples.

Google offers the option to load some of the popular Javascript libraries (Prototype, Script.aculo.us, jQuery, Dojo, and MooTools) from their site.

This has a few advantages to loading them from your own server:

• caching of library files
• files are gzipped
• files are minimized
• it allows quickers loading because of quick servers…
• and because of the possibility to load more files at once (IE allows only 4 concurrent HTTP action from one server at once

Just take a look and try it out.

How about the Yahoo! User Interface library?
Yahoo! offers his own hosting of library files. More information can be found here.
