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.

Making a reset button to put widgets back into a default state


Those that have been rocking the window widgets along for the past three recipes are embodied with unmistakable readiness!

How to do it...

In the Ajax recipe for the window widgets, we placed a block of code within onDrop that was meant to create an object containing the widget locations and send that data server-side for processing. When our reset widget, <input type="button" value="Reset All" id="reset"/> is pressed, we will need to call that same block of code. Start by moving it into its own function.

function record_locations() {
// create an object of widget locations
var data = {};
$$('.hitter').each(function(el) {
var hitter_loc = el.get('id');
var incumbent = el.getFirst().get('id');
eval('data.'+hitter_loc+' = incumbent');
});
// record it
widgetJax.send({data:data});
}

Note

That is the same block of code, and it is now reusable as a custom function.

The next order of business to reset the window locations is to keep...
