MooTools 1.3 Cookbook

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.

Scrolling a news box automatically


In this age of RSS and Twitter feed mania, we are frequently called upon as developers to create elements that can simply incorporate a complexity of data. Scrolling has proven to be a great way to do that since more data than can be displayed at once is still readily available.

Getting ready

Get ready to scroll some text or news by having a lot of text or news: at least more than what would fit within the defined element size.

Please also note that some long blocks of text are represented by ellipses in this and other recipes. They are removed here for display purposes, but necessary in the full example as shown in the code snippets attached with the book.

How to do it...

It is perfectly fine to Ajax-feed content into a DIV and then enact this scrolling effect upon it. Be sure that the Ajax has completed before calling the Fx.Scroll() class, since the instantiation will grab the height of the element, so changing it afterward could have undesirable effects...
