The getAll() method of the IDBIndex interface retrieves all objects inside an IDBIndex.

There is a performance cost associated with looking at the value property of a cursor, because the object is created lazily. To use a feature like getAll(), Gecko would have to create all the objects at once. If you were just interested in looking at each of the keys, for instance, it would be much more efficient to use a cursor. If you were trying to get an array of all the objects in an object store, though, you could use getAll().


var getAllKeysRequest = IDBIndex.getAll(query, count);


An IDBRequest object on which subsequent events related to this operation are fired.


query Optional
A key or an IDBKeyRange identifying the records to retrieve. If this value is null or missing, the browser will use an unbound key range.
count Optional
The number records to return. If this value exceeds the number of records in the query, the browser will only retrieve the first item. 


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.


var myIndex = objectStore.index('index');
var getAllKeyRequest = myIndex.getAllKeys();
getAllKeysRequest.onsuccess = function() {
