The delete()
method of the ContentIndex
interface unregisters an item from the currently indexed content.
Calling delete()
only affects the index. It does not delete anything from the Cache
.
Syntax
ContentIndex.delete(id).then(...);
Parameters
This method receives no parameters.
Return value
Returns a Promise
that resolves with undefined
Exceptions
No exceptions are thrown.
Examples
Below is an asynchronous function, that removes an item from the content index
. We receive a reference to the current ServiceWorkerRegistration
, which allows us to access the index
property and thus access the delete
method.
async function unregisterContent(article) { // reference registration const registration = await navigator.serviceWorker.ready; // feature detect Content Index if (!registration.index) return; // unregister content from index await registration.index.delete(article.id); }
The delete
method can also be used within the service worker
scope.
self.registration.index.delete('my-id');
