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.

Sending a Corvette on a list of errands—extending a class with a chain


To gain some familiarity with how chains work, look in Chapter 7, Knock And the Door Will Open: Events and Listeners for more chaining recipes that do not include the minor complexity of Implements.

Getting ready

Create a canvas where the tasks completed can be written and a trigger to fire each task.

<h1>Taskinator:</h1>
<form action="" method="get">
<input type="button" value="Do Next Task!" id="taskinator"/>
</form>
<h1>Items Done:</h1>
<div id="itemsdone"></div>

How to do it...

  1. 1. Implement the chain

  2. 2. Load the chain with actions

  3. 3. Fire off the actions in the chain

Follow these steps:

  1. 1. Create a class that implements Chain with a method that will append a new action to the class's internal chain:

    var Corvette = new Class({
    Implements: Chain,
    addTask: function(task) {
    this.chain(function(){
    $('itemsdone').set('html',$('itemsdone'). get('html')+'<br/>'+task...
