ContentIndexEvent
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The ContentIndexEvent
interface of the content index defines the object used to represent the contentdelete
event.
This event is sent to the global scope of a ServiceWorker
. It contains the id of the indexed content to be removed.
The contentdelete
event is only fired when the deletion happens due to interaction with the browser's built-in user interface. It is not fired when the ContentIndex.delete
method is called.

});
