IDBKeyRange class
A key range can be a single value or a range with upper and lower bounds or endpoints. If the key range has both upper and lower bounds, then it is bounded; if it has no bounds, it is unbounded. A bounded key range can either be open (the endpoints are excluded) or closed (the endpoints are included). To retrieve all keys within a certain range, you can use the following code constructs:
- Available extensions
- Annotations
-
- @JS()
- @staticInterop
Constructors
- IDBKeyRange()
