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.

Changing graphics upon MOUSEOVER


Many corporate websites make use of this content-changing mechanism to bring a new level of professionalism to their front pages.

Getting ready

Launching off our previous recipe, we add a new level of interaction. Prepare both the mouseover and mouseout Element.addEvents() code blocks, as well as three images to use for the new DOM element that will be updated when our button listeners are fired. This screenshot shows how the lady figurine appears when the Witch button is moused over:

How to do it...

The mouseover action is adjusted with a new line of code that uses the button/image naming structure to update the background style properties of the DOM element pic.

'mouseover':function() {
this.setStyles({'color':'#FFF', 'background-position':'bottom'});
var txt = this.get('text');
this.set('text',text_changer(txt));
$('pic').setStyle('background','#FFF url(07_'+txt+'.jpg) no-repeat top left');
},
...

How it works...

The mouseover action allows the use of the...
