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.

Removing one of multiple event listeners


Getting ready

Keep in mind that mybutton is the trigger for our actions in this recipe.

<input type="button" id="mybutton" value="Greet Me!"/>

How to do it...

Continuing from the previous recipe where we have associated both click and mouseover actions to a triggering INPUT button, we prepare to remove some, but not all, events.

$('mybutton').removeEvents('mouseover');

How it works...

The object function Element.removeEvents() when used without any optional arguments will remove all events bound to an element. Passing in the single argument "mouseover" causes all events bound to that event action to be removed. This allows for the onClick() action previously bound to continue to function while preventing the onMouseover() action entirely.

There's more...

MooTools has two methods in the Element class that are used for removing events. Element.removeEvent() takes two mandatory arguments. Like removeEvents(), the first parameter indicates which action...
