Submit Button

<input type="submit"> defines a submit button.

A submit button is used to send form data to a server. The data is sent to the page specified in the form's action attribute. The file defined in the action attribute usually does something with the received input:

<form name="input" action="html_form_action.asp" method="get">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>

How the HTML code above looks in a browser:

Username: 

If you type some characters in the text field above, and click the "Submit" button,
the browser will send your input to a page called "html_form_action.asp".

The page will show you the received input.
