HTMLFormElement.requestSubmit()

The HTMLFormElement method requestSubmit() requests that the form be submitted using a specific submit button.

Inputs: submitter A submit button that is a member of the form.

Inputs: If the submitter specifies form* attributes, they will override the form’s submission behavior (e.g., formmethod=”POST”).

Inputs: If the submitter has a name attribute or is an image input, its data will be included in the form submission (e.g., btnName=btnValue).

Inputs: If you omit the submitter parameter, the form element itself is used as the submitter.

Exceptions: TypeError Thrown if the specified submitter is not a submit button. NotFoundError DOMException Thrown if the specified submitter isn’t a member of the form on which requestSubmit() was called. The submitter must be either a descendant of the form element or must have a form attribute referring to the form.
