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 12. Advanced DOM Manipulation

Throughout this book, we have used jQuery's powerful DOM manipulation methods to alter the content of the document. We have now seen several ways in which we can insert new content, move existing content around, or remove content altogether. We also know how to alter the attributes and properties of elements to suit our needs.

In Chapter 5, Manipulating the DOM, we were introduced to these important techniques. In this more advanced chapter, we will cover:

  • Sorting page elements using .append()

  • Attaching custom data to elements

  • Reading HTML5 data attributes

  • Creating elements from JSON data

  • Extending the DOM manipulation system using CSS hooks
