EventTarget - Web APIs | MDN (original) (raw)

Widely available *

Note: This feature is available in Web Workers.

The EventTarget interface is implemented by objects that can receive events and may have listeners for them. In other words, any target of events implements the three methods associated with this interface.

Element, and its children, as well as Document and Window, are the most common event targets, but other objects can be event targets, too. For example IDBRequest, AudioNode, and AudioContext are also event targets.

Many event targets (including elements, documents, and windows) also support setting event handlers via onevent properties and attributes.
