Script Smarter: Quality JavaScript from Scratch
|
03/08/2006, By James Edwards and Cameron Adams

JavaScript is an amazingly useful language that offers many unique benefits. With a little consideration for how scripted functionality degrades, you can use JavaScript to bring a whole range of functional, design and usability improvements to your web sites.
This article is actually an excerpt from SitePoint's new title, The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks.
The four chapters included here cover:
a comprehensive introduction to JavaScript including a tour of basic techniques, debugging, and more
the ways in which the Document Object Model can be utilized in JavaScript programming
the practicalities of working with frames, including techniques for working with popups, communicating between frames, and getting scrolling position
an introduction to basic DHTML, which covers event handling, cursor detection, finding the size and position of an element, and more
JavaScript is most commonly used as a client-side language, and in this case the "client" refers to the end-user's web browser, in which JavaScript is interpreted and run. This distinguishes it from server-side languages like PHP and ASP, which run on the server and send static data to the client.
If you'd rather read this primer offline, you can download the chapters in PDF format.
