ContentIndexEvent

Draft: This page is not complete.

The ContentIndexEvent interface of the Content Index API 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.

Properties

A String which identifies the deleted content index via it's id.

Methods

Examples

self.addEventListener('contentdelete', (event) => {
  console.log(event.id);

  // logs content index id, which can then be used to determine what content to delete from your cache

});
