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.

Getting ready

Whenever we are getting ready to introduce elements that move or grow or appear or disappear, we always take into consideration non-sighted users. Be ready for disabled users.

How to do it...

Prepare a form element that has a message that follows the element in the DOM. Any error message can be written there, perhaps some message regarding validation of the element. Let us just whimsically play a name game to demonstrate.

<form action="" method="get">
<label for="name">Name: </label>
<input type="text" name="name" value=""/>
<span id="error_message"></span>
<br/>
<input type="button" value="submit"/>
</form>

How it works...

Each time a key is released within the form element, a bound function calls an effect that is chained to glow smoothly in and smoothly out. Each successive...
