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.

Querying Mr. Clean's MP3 list!


Once our MP3 list gets too long to manage, users will desire a means of sorting through the rubbish and finding only the really good tunes.

Getting ready

This recipe launches off the work we accomplished in the previous recipe. Be familiar with that and then watch for the query data to be sent to the server-side script below.

How to do it...

There is but one small change here; it only adds a few lines of code. We grab the value of the input box and pass it as the optional argument. The server-side script then cleans this value, and uses it in a matching glob to find files like that string:

function send_query() {
// prepare the data to send
var el = $('mp3_query');
data = {'mp3_query':el.get('value')};
// make the actual ajax (json) call
myJax.send({data:data});
}

How it works...

In the last chapter, our sending widget labeled JSON MP3 List was calling myJax, the JSON object directly. In this example, we could create the data structure necessary to send as the optional...
