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.

Upgrading all Corvettes via recall—Implement AND Extend in unison!


But wait, we can do even more with Implements and Extends! Prepare to see them used simultaneously.

Getting ready

Starting off from where our last recipe left off will get us ready.

<h1>Speeds Before</h1>
<div id="before"></div>
<h1>Speeds After</h1>
<div id="after"></div>
// create two classes from the base Class
var Car = new Class({
showSpeed: function() { return 0; }
});
var SportyEngine = new Class({
speed: 10,
showSpeed: function() { return this.speed; }
});
// Extend one, Implement the other
var Corvette = new Class({
Extends: Car,
speed: 1,
showSpeed: function() {
// this.parent calls the overridden class
return this.parent()+1;
}
});

How to do it...

In this example, we want to not only speed up the 'vettes that have the base chassis, but also the ones with the sportier engine. To do this we must implement SportyEngine while extending Car, so that the speed can still cascade...
