This book covers what xHTML language is, when to use it, and how to develop programs that use xHTML language.

XHTML Basic is one of the most widely used languages to communicate with mobile communication devices. XHTML Basic is the World Wide Web’s Consortium’s (W3C) initiative to provide a common markup language for wireless devices and other small devices with limited memory. The W3C released its recommendation for XHTML Basic in December 2000. Also, WAP 2.0 Specification includes XHTML Basic along with WML and WMLScript. WAP 2.0 basically allows WML and WMLScript to be embedded within XHTML Basic.

Sample Text and Diagrams

There are 15 explanatory diagrams and 13 code examples in this book

Simple xHTML Basic Forms

Forms are structured displays of screen information that usually allows a user to enter and edit information in predefined fields on specific areas of the form. xHTML uses forms to assist the user in entering and providing information to web servers such as email address, search keywords, and addresses. Forms display information prompts to the user that allows the user to select which information item(s) to enter and send. The form is used to help route the user data to the web server, which passes it to a computer graphics interface (CGI) script, usually written in C++, Perl, Java, or some other scripting language. The data is sent to the CGI script when the submit button is pushed on the XHTML Basic document. The script then processes the data and returns information in the form of an XHTML Basic document to the web browser.

Example 11 and figure 1.12 shows a XHTML Basic document that asks for the users name and email address. It uses the input type “text” for the inputting of the name and the email, and it uses the input type “submit” and “reset” for the buttons on the bottom of the screen.

Example 11

Figure 1.12. Forms Example

Forms can contain visual and non-visual components. Visible components include clickable buttons and other graphical user interface components for the user to interact. Non-visual components, called hidden inputs, store data that the document author wishes to pass to the cgi script.
