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.

Saving space on our site: creating a transition that grows an IMG from small to large


In this recipe we will learn about how to use the mouse over an image technique to enlarge the image.

Getting ready

Prepare a thumbnail image that is constrained via a CSS class definition, .smaller_image.

<img src="08_nature.jpg" alt="Nature" class="smaller_img"/>
<style type="text/css">
.smaller_img { width:100px; }
.bigger_img { width:500px; }
</style>

How to do it...

Much like the previous recipe, we use the MooTooled element property, which comes from the Fx.Morph() class. The difference in this recipe is that we pass to Element.morph() the class that contains the style definition to transition to.

$$('img').addEvents({
'mouseover':function() {
this.morph('.bigger_img');
},
'mouseout':function() {
this.morph('.smaller_img');
}
});

How it works...

Once the mouseover and mouseout events are added by the Element.addEvents() construct, each event calls the assigned morph and passes...
