Form elements can be used as a form of global variables - holding state that can be used and shared by all the javascript in a single page.

If you need to pass data to another page, then forms can make life easier - using a GET form, the values on the form will be passed to the page referenced in the form action attribute as key-value pairs. If you use the POST method they will be transferred in the headers.
