jQuery 1.3 Released – How to use jQuery

jQuery is a “fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.  jQuery is designed to change the way that you write JavaScript.”

jQuery version 1.3 was released yesterday.

Some new features in 1.3 are:

• Sizzle – a brand new CSS selector engine
• Live Events – event delegation with a jQuery twist
• jQuery Event Overhaul – simplified event handling
• HTML Injection Rewrite – Lightning-fast HTML appending
• Offset Rewrite – Super-quick position calculation
• No more browser sniffing!!
• New API Browser - http://api.jquery.com/

I have yet to play with jQuery 1.3, but will post my impressions after I get some hands on time with it.

Are you new to jQuery?
jQuery is a library that you can include on your web projects.  jQuery enables HTML and JavaScript developers to rapidly deploy functionality that traditionally is more complex.  Through browser independent APIs, developers and designers can implement event handling, CSS changes, animations, popular web 2.0 effects, or other common function of web 2.0+ sites. 

Downloading jQuery
You can get jQuery by going to jQuery.com and downloading the version of jQuery you want:

• Production version – 18kb – Minified for production environments (don’t try to debug this, its a nightmare)
• Development version – 114kb – Developers can go in and see how things work with this version, but the footprint is huge
