Structure of content on the web

Interfaces for building web applications

<form> is submitted.

Note that the submit event fires on the <form> element itself, and not on any submitter property, which is the button that was invoked to trigger the submit request.

The submit event fires when:

the user clicks a submit button,
the user presses Enter while editing a field (e.g. <input type="text">) in a form,
a script calls the form.requestSubmit() method

However, the event is not sent to the form when a script calls the form.submit() method directly.

Note: Trying to submit a form that does not pass invalid event. In this case, the validation prevents form submission, and thus there is no submit event.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("submit", (event) => {});

onsubmit = (event) => {};

Event type

A Event.

Event properties

In addition to the properties listed below, this interface inherits the properties of its parent interface, Event.

submitter Read only: An HTMLElement object which identifies the button or other element which was invoked to trigger the form being submitted.

Examples

This example uses Event.timeStamp whenever that occurs, then prevents the default action of submitting the form.
