onCleanup

fun onCleanup(withParent: Boolean, f: Cleaner)(source)

Specify a listener to be called when this element is removed from the DOM.

Parameters

withParent

If true this cleaner will be called if this element is cleaned up, or if any ancestor element of this ElementCreator is cleaned up. Otherwise it will only be cleaned up if this ElementCreator is cleaned up specifically.

As a rule-of-thumb, use 'true' for anything except deleting DOM elements.
