Learning jQuery 1.3

Overview of this book

<p>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. <br /><br />Revised and updated for version 1.3 of jQuery, this book teaches you 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.<br /><br />In this book, the authors share their knowledge, experience, and enthusiasm about jQuery to help you get the most from the library and to make your web applications shine. The book introduces jQuery and shows how you can write a functioning jQuery program in just three lines of code. It then guides you through CSS selectors and shows how to enhance the basic event handling mechanisms to give them a more elegant syntax. You will then learn to add impact to your actions through a set of simple visual effects and also to create, copy, reassemble, and embellish content using jQuery's DOM modification methods. You will also learn to send and retrieve information with AJAX methods. The book will then step you through many detailed, real-world examples and even equip you to extend the jQuery library itself with your own plug-ins.</p>

Tools for Firefox


Mozilla Firefox is the browser of choice for the lion's share of web developers, and therefore has some of the most extensive and well-respected development tools.

Firebug

The Firebug extension for Firefox is indispensable for jQuery development:

Some of the features of Firebug are :

  • An excellent DOM inspector for finding names and selectors for pieces of the document

  • CSS manipulation tools for finding out why a page looks a certain way and changing it

  • An interactive JavaScript console

  • A JavaScript debugger that can watch variables and trace code execution

Web developer toolbar

This not only overlaps Firebug in the area of DOM inspection, but also contains tools for common tasks like cookie manipulation, form inspection, and page resizing. You can also use this toolbar to quickly and easily disable JavaScript for a site to ensure that functionality degrades gracefully when the user's browser is less capable:

Venkman

Venkman is the official JavaScript debugger for the Mozilla project. It provides a troubleshooting environment that is reminiscent of the GDB system for debugging programs that are written in other languages.

Regular expressions tester

Regular expressions for matching strings in JavaScript can be tricky to craft. This extension for Firefox allows easy experimentation with regular expressions using an interface for entering search text:
