MooTools 1.3 Cookbook

By: Jay L Johnston

Overview of this book

MooTools is a JavaScript framework that abstracts the JavaScript language. JavaScript itself, complex in syntax, provides the tools to write a layer of content interaction for each different browser. MooTools abstracts those individual, browser-specific layers to allow cross-browser scripting in an easy-to-read and easy-to-remember syntax. Animation and interaction, once the domain of Flash, are being taken by storm by the MooTools JavaScript framework, which can cause size, shape, color, and opacity to transition smoothly. Discover how to use AJAX to bring data to today's web page users who demand interactivity without clunky page refreshes. When searching for animation and interactivity solutions that work, MooTools 1.3 Cookbook has individual, reusable code examples that get you running fast! MooTools 1.3 Cookbook readies programmers to animate, perform AJAX, and attach event listeners in a simple format where each section provides a clear and cross-browser compatible sketch of how to solve a problem, whether reading from beginning to finish or browsing directly to a particular recipe solution. MooTools 1.3 Cookbook provides instant solutions to MooTools problems – whatever you want to do with MooTools, this book will tell you how to do it. MooTools 1.3 Cookbook is presented in a progressive order that builds concepts and ideas, while simultaneously being a collection of powerful individual, standalone, recipe solutions.

Using Firefox's Firebug to troubleshoot asynchronous calls


The trickiest part of Ajax development is knowing what is happening in the seemingly black box request. Even if we define what data and URL we are using to make the request, if something happens that we have not accounted for in our coding, we may never know what was returned from the server.

Getting ready

Let us ready ourselves for this chapter by having one of the best tools to debug Ajax requests. We make ourselves familiar with Firefox Firebug, firstly, by downloading the Firefox browser from http://firefox.com. Once that is installed, we choose Tools from the horizontal menu, and then select Add-ons from the resulting drop-down menu. Finding and installing the Firebug add-on is simple; just search for Firebug and follow the directions to install it and restart Firefox. Once it is installed a tiny firebug icon will be evident in the status bar:

How to do it...

Clicking the icon once will open the Firebug Window (or press F12). Once...
