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.

Making a golf ball ease up to a hole and stop


Using transitions to animate image movement on the screen is great fun and, it works on the iPhone.

Getting ready

Prepare three images: the golf green, the golf ball, and the golf ball's shadow.

<div id="green"></div>
<style type="text/css">
#green {
margin:0 auto;
background:transparent url('08_golf_green.jpg') no-repeat 0 0;
width:500px; height:500px;
}
</style>
<script type="text/javascript">
// inject the ball
var ball = new Element('img',{
id: 'ball',
src: '08_golf_ball.png',
style: 'width:10px; position:absolute;',
morph: {
link:'chain',
transition:'linear'
}
}).inject('green','top');
// inject the ball's shadow
var shad = new Element('img',{
...
alert('Ready?');

We also need the movement coordinates of the ball.

// top, left, width
var ballmov = [
[150, 10, 10],
[ 20, 20, 10], // bounce 1
[160, 30, 10],
[100, 40, 10], // bounce 2
[180, 50, 15],
[140, 75, 20], // bounce 3
[220,100, 25],
[200,150, 30], // bounce...
