Chapter 8. Forms

When you're working with server-side technologies, forms are the one aspect of HTML that is most useful since it enables users to "communicate" with the serverby entering data into a form and then submitting that form to the server.

From a JavaScript point of view, HTML forms are very interesting as well. The options HTML is offering are somehow limited, and JavaScript can come to the rescue here. User data must be validated, forms may accept only certain kinds of input, form submission can be possible only when certain requirements are met. All thisand moreis possible with JavaScript, as covered in this chapter.
