Introduction
JavaScript has gone though a huge transformation, from being something that was nice to know to being essential
to developing web sites that are fully featured and take full advantage of the new capabilities built into browsers. The
amount of attention given to JavaScript though libraries and frameworks has grown at an accelerated rate.
This was not always the case. JavaScript was first introduced as LiveScript in 1995 by Netscape. Over time,
Microsoft’s Internet Explorer adopted it and Netscape changed the name to JavaScript with the release of Netscape
Navigator 2. As the two companies continued to compete, support was not that good. At worst, developers had to make
two different versions of a site to support the most popular browsers (which, at the time, were Netscape 4 and Internet
Explorer 4).
Browser support has improved greatly. The World Wide Web Consortium (W3C), working with browser makers,
developed a standard way of representing and interacting with HTML documents, called the Document Objet Model
(DOM), and a scripting language, called ECMAScript. Over the years, compliance with these standards has improved.
This book starts with the basics and gives you a good foundation on how to write JavaScript in an unobtrusive
way, keeping your structure (HTML), presentation (CSS), and behavior (JavaScript) separate. There are also examples
of how to keep your sites accessible for visitors using screen readers, as well as examples of how to develop your site if
JavaScript is not available. We also cover subjects like objected detection versus browser detection, AJAX, HTML 5 Form
validation, and an introduction to jQuery.
The goal of this book is to help you understand JavaScipt. If you haven’t looked at JavaScript in a while, you’ll be
glad to know a lot has changed for the better. You can use this book as a guide to update your skills. If you are new to
JavaScript, this book helps you from the beginning. We start with explaining what a variable is and later move on to how
to add Google Maps to your site.
This book is full of examples you can use to enhance your site and add features based on the enhanced capabilities
built into current browsers.
