What is the purpose of the form submit button?

The purpose of the form submit button is to activate and process data. When a user completes a form on a website, the submit button serves as the final action to send the collected information to the server for processing. This could involve storing the data in a database, sending an email, or performing other tasks based on the information provided by the user. The activation occurs when the user clicks the submit button, triggering the form submission process.

The other functionalities mentioned in the other choices, such as displaying data, resetting fields, or previewing the form, do not capture the primary role of the submit button. Displaying data is typically handled through other means, such as data retrieval and presentation mechanisms. Resetting fields would involve a different function entirely, usually tied to a reset button, which clears the form before submission. Previewing the form is also not the submit button’s function; that feature might involve a separate action or button designated for previewing the information before final submission. Thus, the main utility of the submit button centers on activating the submission and processing of data entered in a form.
