executing a request. However, the steps are slightly modified such that instead
of creating a new IDBRequest, it reuses the request originally created when this
cursor was created. The done flag on the request is set to false before the req
uest is returned. The steps are run with the cursor's source as source and the s
teps for iterating a cursor as operation, using this cursor as cursor and the ke
y parameter as key."> |
