MooTools 1.3 Cookbook

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.

Fading through a rotating group of images—slideshow!


Typically, it seems, the DOM markup for a slideshow is harrowing. This example will show how that markup can be made much more straightforward.

Getting ready

Ready our DOM with a simple, unimposing markup. To allow the page to gracefully degrade in the absence of JavaScript, place the initial image as the background of #fodaddy.

<div id="fodaddy">
<div id="fo"></div>
</div>
<style type="text/css">
#fodaddy {
width:367px;
background-image:url('08_cow_one.jpg');
}
#fo, #fodaddy {
height:318px;
}
</style>

How to do it...

Inject the main, viewable image behind #fo and set #fo to a zero opacity so that it is invisible, allowing the main image to be the only item seen by users. Place a new image in #fo, which is our curtain of sorts, and then pull the curtain on the main image by fading in a bit of fo; then repeat endlessly in a loop.

Identify which images to loop through. Remember that the image in the first...
