6 CHAPTER 1 ■ INTRODUCING JQUERY After restarting Firefox, an icon will appear in the status bar that looks like a lightning bug. Clicking that icon will bring up the Firebug controls, starting with the console (see Figure 1-2). Figure 1-2. The Firebug add-on opens to the console panel ■ Note Firebug is useful for much more than JavaScript debugging. It's an invaluable addition to any web developer's arsenal.

SETTING UP A LOCAL TESTING ENVIRONMENT CHAPTER 1 ■ INTRODUCING JQUERY Though setting up a local testing environment is not required for the exercises presented in this book, doing so is a good development practice. Testing locally allows for quicker, more secure development and is generally easier than trying to develop on a remote server. Installing XAMPP To quickly and easily set up a local development environment on your computer, download and install XAMPP using the following steps: 1. Visit http://www.apachefriends.org/en/xampp.html, and download the latest version of XAMPP for your operating system. 2. Open the downloaded file. For a PC, run the EXE file, select a directory, and install. For a Mac, mount the DMG, and drag the XAMPP folder into your Applications folder. 3. Open the XAMPP Control Panel in the XAMPP folder, and start Apache. 4. Navigate to http://localhost/ to ensure than XAMPP is working. If so, the XAMPP home page will let you know. In addition to the Windows and Mac versions of XAMPP, there are distributions for Linux and Solaris. Each operating system has quirks when installing XAMPP, so refer to the help section for additional information on getting a local testing environment running on your machine. Including jQuery in Web Pages To use jQuery in a project, the library needs to be loaded in your HTML document to give your script access to the library’s methods. If the library is not loaded first, any scripts using jQuery syntax will likely result in JavaScript errors. Fortunately, loading jQuery is very simple, and there are several options available to developers to do so. Including a Downloaded Copy of the jQuery Library The first option for including jQuery in a project is to save a copy of the library within your project’s file structure and include it just like any other JavaScript file: 7
