Retrieves a list of event listeners associated with a DOM element. The list does include host listeners, but it does not include event listeners defined outside of the Angular context (e.g. through addEventListener).

Usage notes

Given the following DOM structure:

<my-app>
  <div (click)="doSomething()"></div>
</my-app>

Calling getListeners on <div> will return an object that looks as follows:

{
  name: 'click',
  element: <div>,
  callback: () => doSomething(),
  useCapture: false
}
