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.

Stopping a listener from executing a chain of events


It is a feature not a bug. That jocularity may work with the right client, and using it carefully, and in the right context, may prevent a client from being angry about unexpected behavior.

Getting ready

This recipe, an extension of the last two, alters the method in which we prevent the chain from firing. Ready our receptors-of-twisted-facts to perceive the idea that a bug can be a feature.

There may be a need to stop a listener from activating a chain while still keeping the chain of events for later use.

How to do it...

Reuse the INPUT button with ID my_cancel, yet instead of calling the method to remove the stack of actions, Just remove the click action of the event.

$('mycancel').addEvent('click',function() {
// this removes the listener that was firing the chain
$('mybutton').removeEvents('click');
// but it does not remove the chain of events itself
my_chain.callChain.delay(1000,my_chain);
my_chain.callChain.delay(1000,my_chain);
my_chain...
