GlobalEventHandlers.onclose
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The onclose
property of the
GlobalEventHandlers
mixin is an event handler for
processing close
events sent to a <dialog>
element.
The close
event fires when the user closes a <dialog>
.
Note: To handle the closing of a window, use
onbeforeunload
or
onunload
.
Syntax
target.onclose = functionRef;
Value
functionRef
is a function name or a function
expression. The function receives an Event
object as its sole
argument.
Only one onclose
handler can be assigned to an object at a time. You may
prefer to use the EventTarget.addEventListener()
method instead, since
it's more flexible.
