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.

Making a reset button to remove all products from a shopping cart


This is the last recipe in this series. Please join us from the first recipe through the fifth by beginning at the first page ofChapter 6,Easy Come, Easy Go: Drag and Drop.

How to do it...

Adding just a couple of lines in a few key places set us up to remove all the cart business logic and presentation logic that is being stored client-side for our user.

  • Adding a widget to remove all items

    <a id="clear_all_trigger">Remove All Products</a>
    <style type="text/css">
    #clear_all_trigger { cursor:pointer; font-color:#00F; text-decoration:underline; }
    <style>
    

    When placing the widget, we give some thought to design and align the text left, color it, and so on. What is more important, though, is that our widget needs to appear clickable. Any HTML A tag without the HREF attribute will not appear as clickable. Setting the style cursor:pointer; solves that usability issue.
