- def get(key: |[IDBKey, IDBKeyRange]): IDBRequest[S, IDBValue]
Returns an IDBRequest object, and, in a separate thread, returns the object store selected by the specified key.
Returns an IDBRequest object, and, in a separate thread, returns the object store selected by the specified key. This is for retrieving specific records from an object store.
Note: This method produces the same result for: a) a record that doesn't exist in the database and b) a record that has an undefined value. To tell these situations apart, call the openCursor method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.
- def getAll(query: UndefOr[|[IDBKeyRange, IDBKey]] = js.native, count: UndefOr[Double] = js.native): IDBRequest[S, Array[IDBValue]]
Returns an IDBRequest object containing all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.
Returns an IDBRequest object containing all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.
If a value is successfully found, then a structured clone of it is created and set as the result of the request object.
This method produces the same result for:
- a record that doesn't exist in the database
- a record that has an undefined value
To tell these situations apart, you either call
- the openCursor method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.
- the count method with the same key, which will return 1 if the row exists and 0 if it doesn't.
- def getAllKeys(query: UndefOr[|[IDBKeyRange, IDBKey]] = js.native, count: UndefOr[Double] = js.native): IDBRequest[S, Array[IDBKey]]
Returns an IDBRequest object retrieves record keys for all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.

- def openCursor(range: UndefOr[|[IDBKeyRange, IDBKey]] = js.native, direction: UndefOr[IDBCursorDirection] = js.native): IDBRequest[S, IDBCursorWithValue[S]]

- returns
