Learning jQuery - Fourth Edition

By: Karl Swedberg, Jonathan Chaffer

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. LearningjQuery - Fourth Edition is revised and updated version 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 take 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 that is ready for consumption by the browser. The techniques we have seen in this book have shifted this arrangement slightly by using CSS techniques to alter the appearance of that HTML document on the fly. To really flex our JavaScript muscles, though, we'll need to learn to alter the document itself.

In this chapter, we will cover:

  • Modifying the document using the interface provided by the Document Object Model (DOM)

  • Creating elements and text on a page

  • Moving or deleting elements

  • Transforming a document by adding, removing, or modifying attributes and properties
