Learning jQuery - Fourth Edition - Fourth 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. 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.

Loading data on demand

Underneath all the hype and trappings, Ajax is just a means of loading data from the server to the web browser or client without a visible page refresh. This data can take many forms, and we have many options for what to do with it when it arrives. We'll see this by performing the same basic task in many ways.

We are going to build a page that displays entries from a dictionary, grouped by the starting letter of the dictionary entry. The HTML defining the content area of the page will look like this:

<div id="dictionary">

Yes, really! Our page will have no content to begin with. We are going to use jQuery's various Ajax methods to populate this <div> tag with dictionary entries.
