12 Dec 2006 This tutorial focuses on key aspects of the W3C XForms 1.0 standard to produce a fully functional Web-based shopping cart. With this approach, the reader will get a good start at creating real-world applications with XForms, without having to learn the entire XForms specification.
In this tutorial
- Details for building an online shopping cart using XForms.
- Computes totals, discounts, account for warranties, various delivery options, and is comparable to many existing shopping carts available on the Web today.
- General usage patterns for forms modification using XForms.
Prerequisites
This tutorial is written for Web application developers familar with
HTML, HTML forms, XML, CSS and other related Web technologies. Though knowing
these technologies would be helpful, they are not required to be able to
gain a better understanding of XForms by using this tutorial.
System requirements
In order to view or render these forms, typically a Web browser plus an add-on is needed. There are a few options that don't require add-ons; these are either server-based or JavaScript™/ECMAScript-based. For this tutorial, Mozilla's XForms add-on 0.7 is used with Firefox 1.5.0.7, but many others will do just fine. It is not the intent of this tutorial to highlight differences in current implementations, but to provide enough information to develop forms that can be used with most viewers.
To view the demos included in this tutorial, JavaScript must be enabled in your browser and Macromedia Flash Player 6 or higher must be installed. You can download the latest Flash Player at http://www.macromedia.com/go/getflashplayer/.
