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.

Creating a welcome message based on a JavaScript cookie


Display an Alert "Hello, [Name]" to our visitor, with a cookie that was set some time earlier.

How to do it...

The MooTools Cookie class makes it surprisingly easy to create, read, access, and purge cookies. The method Cookie.write() takes a key, a value, and optionally an object of options; for instance, the option duration takes an integer that represents the number of days a cookie should be kept by a visitor. Cookie.read(), terribly simple in syntax, takes the key of the cookie value that we wish to read. If empty the value is, it returns false. And, of course, we could not properly purge any cookie without the handy Cookie.dispose() whose first parameter is identical to read() and second parameter will merge the passed object of options with the existing cookie object options.
