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');
