The <form> element
A web page's <form> element is used to create a form on the page, collect user data and send that data to an application for processing. For example, when you shop online, you fill out a form indicating the product and the number of items and then submit it for processing. The DOM HTMLFormElement Interface provides the properties and methods. Forms must have a unique name Forms also must contain a method which says how the data will be sent to the application. Examples show how to use the post and get methods to send user data to an application.
