Learning jQuery, Third Edition

Overview of this book

To build interesting, interactive sites, developers are turning to JavaScript libraries such as jQuery to automate common tasks and simplify complicated ones. Because many web developers have more experience with HTML and CSS than with JavaScript, the library's design lends itself to a quick start for designers with little programming experience. Experienced programmers will also be aided by its conceptual consistency.Learning jQuery Third Edition is revised and updated for version 1.6 of jQuery. You will learn the basics of jQuery for adding interactions and animations to your pages. Even if previous attempts at writing JavaScript have left you baffled, this book will guide you past the pitfalls associated with AJAX, events, effects, and advanced JavaScript language features.Starting with an introduction to jQuery, you will first be shown how to write a functioning jQuery program in just three lines of code. Learn how to add impact to your actions through a set of simple visual effects and to create, copy, reassemble, and embellish content using jQuery's DOM modification methods. The book will step you through many detailed, real-world examples, and even equip you to extend the jQuery library itself with your own plug-ins.

Chapter 5. Manipulating the DOM

The web experience is a partnership between web servers and web browsers. Traditionally, it has been the domain of the server to produce an HTML document ready for consumption by the browser. The techniques we have seen have shifted this arrangement slightly, by using CSS techniques to alter the appearance of that HTML on the fly. To really flex our JavaScript muscles, though, we'll need to learn to alter the document itself.

With jQuery, we can easily modify the document by using the interface provided by the Document Object Model (DOM). This will allow us to create elements and text in a web page, whenever we need to. We can also make any of these things vanish, or indeed transform them on the fly by adding, removing, or modifying their attributes.
