Murach's jQuery, 2nd Edition

What this book does

Section 1: The least you need to know about JavaScript to get the most from jQuery

To use jQuery, you need to know how to use at least a subset of JavaScript. That’s why section 1 of this book presents a crash course in the JavaScript skills that you need for using jQuery. This section also serves as a JavaScript reference when you can’t remember how some of the JavaScript code in a jQuery example or application works.

This section works best if you have some programming experience, even if that experience isn’t with JavaScript. The more experience you have, the faster you can move through this section.

Note, however, that this section also works for people with no programming experience. It just takes longer to go through the material. For some beginners, though, a better alternative is to start with Murach’s JavaScript and then go on to this jQuery book. In the long run, you’re probably going to want to master both.

Section 2: The core jQuery skills for every web developer

In this section, you’ll learn how to use jQuery to create JavaScript applications like image swaps, collapsible panels, slide shows, carousels, user-friendly forms…and more…with far less coding than you’d have to do in native JavaScript.

To begin, chapter 5 presents the jQuery selectors, methods, and event methods that you’ll use most often. Then, the next four chapters build on that base as they focus on how to use effects and animations, how to use the many plugins that are available for jQuery, how to create your own plugins, how to work with forms and controls, and how to manipulate and traverse the DOM. When you complete this section, you can go on to any of the three sections that follow.

Section 3: Enhance your web pages by using jQuery UI

Besides the core jQuery library, jQuery provides the jQuery UI (User Interface) library. This library helps you build features that your site visitors may appreciate, all with just a few lines of code. So this section shows you how to use jQuery UI to create widgets like tabs, accordions, and datepickers...interactions like draggable, droppable, and sortable...and effects like color and class transitions.

Section 4: Speed up response times and add content feeds with Ajax and JSON

Ajax and JSON can be used to get data from a server and add it to a web page without reloading the entire page, and that can significantly improve response times for users (if you’ve ever scrolled around a Google Map, you’ve seen this in action). But to be honest, the coding can be mind-bending. Fortunately, jQuery provides methods that make it far more manageable.

So in this section, you’ll learn how to use jQuery with Ajax and JSON to deliver data to your websites. First, you’ll learn the basics. Then, you’ll learn how to use these skills with APIs like the ones for Flickr and Google Maps and thus add popular content to your pages. Last, you’ll learn how to use HTML5 APIs like Web Storage and Web Workers with Ajax and JSON.

Section 5: Mobile websites made easier with jQuery Mobile

This section shows you how to use the jQuery Mobile library to develop web pages for mobile devices with the look-and-feel of native applications. For large, established websites, this is often a practical alternative to responsive web design. In fact, there’s no better way to build separate websites for mobile devices.
