The HTMLFormElement.submit() method submits a given <form>.

This method is similar, but not identical to, activating a form's submit <button>. When invoking this method directly, however:

• No submit event is raised. In particular, the form's onsubmit event handler is not run.
• Constraint validation is not triggered.

The HTMLFormElement.requestSubmit() method is identical to activating a form's submit <button> and does not have these differences.

A form control (such as a submit button) with a name or id of submit will mask the form's submit method. Trying to call myForm.submit(); throws an error "submit is not a function" because in this case submit refers to the form control which has a name or id of submit.

<input> with attribute type="submit" will not be submitted with the form when using HTMLFormElement.submit(), but it would be submitted when you do it with original HTML form submit.
