In this module, you will learn how to use HTML forms to collect input from a Web page user. You will learn to use all the standard HTML form elements: checkboxes, text entry boxes, pulldown menus, and radio buttons. In addition, you will learn much more about JavaScript (you should have a basic knowledge of JavaScript already). Specifically, you will use JavaScript to write scripts that provide tailored responses for data entered into HTML forms.

For example, you will learn how to:

• construct HTML forms with a variety of elements including text entry boxes, pulldown menus, checkboxes, and radio buttons
• employ conditional statements in JavaScript
• write JavaScript scripts to provide tailored response to Web page users who enter data in an HTML form
• write JavaScript scripts to validate data entered into HTML forms.
