IDBIndex.getAllKeys()

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

JavaScript
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 IDBKeyRange identifying 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

JavaScript
var myIndex = objectStore.index('index');
var getAllKeyRequest = myIndex.getAllKeys();
getAllKeysRequest.onsuccess = function() {
  console.log(getAllKeysRequest.result);
}
