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 an error message from the page with a fade effect


We are all experienced with showing an error, but what happens to that error once the user has read it and begun to move on with their life? Fade out the error, or any block of text using opacity to help users have a better understanding of what the application is asking them to do.

Getting ready

Prepare to use this recipe in an application by listing out the form validation elements. Knowing which collection of elements must be integer, or string, and so on, will help us to write form validation that is more reusable, since we can reuse code that is written upon groups of elements more easily than we can use individual element's form validation. Once we are ready to do that, we will be eager to see how appealing we can make our error message!

How to do it...

Element.Fade() helps us make an appealing message fade into place with utterly amazing simplicity. But do not stop there, be sure to have the message fade out with equal appeal...
