continue
- continue(key?: IDBValidKey): void
Advances the cursor to the next record in range.
Parameters
Optionalkey: IDBValidKey
Returns void

- continuePrimaryKey(key: IDBValidKey, primaryKey: IDBValidKey): void
Advances the cursor to the next record in range matching or after key and primaryKey. Throws an "InvalidAccessError" DOMException if the source is not an index.
Parameters
- key: IDBValidKey
- primaryKey: IDBValidKey
Returns void
delete
- delete(): IDBRequest<undefined>
Delete the record pointed at by the cursor with a new value.
If successful, request's result will be undefined.
Returns IDBRequest<undefined>
update
- update(value: any): IDBRequest<IDBValidKey>
Updated the record pointed at by the cursor with a new value.
Throws a "DataError" DOMException if the effective object store uses in-line keys and the key would have changed.
If successful, request's result will be the record's key.
