FormDataEvent()

The FormDataEvent() constructor creates a new FormDataEvent object instance.

new FormDataEvent(type[, formEventInit]);

type

A DOMString representing the name of the event.

formEventInit Optional

A FormEventInit dictionary, which can take the following optional fields:

• bubbles: a Boolean indicating whether the event bubbles. The default is false.
• cancelable: a Boolean indicating whether the event can be cancelled. The default is false.
• composed: a Boolean indicating whether the event will trigger listeners outside of a shadow root (see Event.composed for more details). The default is false.
• formData: A FormData object to pre-populate the FormDataEvent with. This would then be accessed through the FormDataEvent.formData property.

let fd = new FormData();
fd.append('test', 'test');

let fdEv = new FormDataEvent('formdata', { formData: fd });

for (let value of fdEv.formData.values()) {
  console.log(value);
}
