{{APIRef("DOM Events")}}

Method overview

void handleEvent(in nsIDOMEvent event);

Methods

handleEvent()

This method is called whenever an event occurs of the type for which the EventListener interface was registered.

void handleEvent(
  in nsIDOMEvent event
);
Parameters
event
The DOM {{ domxref("Event") }} to register.

Remarks

As the interface is marked with the [function] flag, all JavaScript Function objects automatically implement this interface. Calling the {{ manch("handleEvent") }} method on such an implementation automatically invokes the function.
