Microsoft released a mostly-compatible version of the language called JScript with IE 3 several months later. Netscape submitted the language to Ecma International , a European standards organization, which resulted in the first edition of the ECMAScript standard in 1997. The standard received a significant update as ECMAScript edition 3 in 1999, and has stayed pretty much stable ever since. The fourth edition was abandoned, due to political differences concerning language complexity. Many parts of the fourth edition formed a basis of the new ECMAScript edition 5, published in December of 2009. This stability is great news for developers, as it's given the various implementations plenty of time to catch up.

Harry Maugans » How to Create an Animated, Sliding, Collapsible
In this tutorial, we will create functions to slide DIVs up and down. It supports multiple animations happening simultaneously, as well as a variable animation length.

jQuery: The Write Less, Do More, JavaScript Library
Congratulations! You just ran a snippet of jQuery code. Wasn't that easy? There's lots of example code throughout the documentation on this site. Be sure to give all the code a test run to see what happens.Event Handling Back in the heady days of Web 1.0, if you wanted to have an object on the page react to something like a click, you would simply go ahead and attach an onclick attribute.

24 ways: Writing Responsible JavaScript
Working largely with b2b sites and restricted environments, I never knew it was out of fashion. It is a tool, much like a shovel, a screwdriver or a towel. While a towel is handy in every situation, as every HHGTTG reader knows, JavaScript has its place and its merits, but also its limitations and places it shouldn’t be applied to. You can use a screwdriver to screw in screws or to clean your ears, however, the latter needs real skill, determination and a lack of fear of injuring yourself.

On the agenda is creating HTTP 2.0, a faster, modern approach to internet communication.10) addEvent() Surely a staple to event attachment! Regardless to what version you use written by whatever developer, it does what it says it does.
