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.

While SubmitEvent offers no methods of its own, it inherits any specified by its parent interface, id is used to identify which payment processor the button corresponds to.

let form = document.querySelector("form");
form.addEventListener("submit", (event) => {
  let submitter = event.submitter;
  let handler = submitter.id;

  if (handler) {
    processOrder(form, handler);
  } else {
    showAlertMessage(
      "An unknown or unaccepted payment type was selected. Please try again.",
      "OK",
    );
  }
});
