The proposed getAllKeys() method of the IDBIndex interface would instantly retrieve the keys of all objects inside an object store, setting them as the result of the request object.
Note: This method is not currently included in the IndexedDB spec or available in any browsers, but is being considered for future addition.
Syntax
var myIndex = objectStore.index('index');
var getAllKeysRequest = myIndex.getAllKeys(query);
Returns
An IDBRequest object on which subsequent events related to this operation are fired.
Parameters
- query Optional
- A key or an
IDBKeyRangeidentifying the keys to retrieve. If this value is null or missing, the browser will use an unbound key range.
Exceptions
This method may raise a DOMException of the following types:
| Exception | Description |
|---|---|
| TransactionInactiveError | This IDBIndex's transaction is inactive. |
InvalidStateError |
The IDBIndex has been deleted or removed. |
Example
var myIndex = objectStore.index('index');
var getAllKeyRequest = myIndex.getAllKeys();
getAllKeysRequest.onsuccess = function() {
console.log(getAllKeysRequest.result);
}
