IDBIndex.getAllKeys

The proposed getAllKeys() method of the IDBIndex interface would instantly retrieve the keys of all objects inside the index, setting them as the result of the request object.

Syntax

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

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.
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. If it is lower than 0 or greater than 2³²-1 a TypeError exception will be thrown.

Return Value

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

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.

A TypeError exception is thrown if the count parameter is not between 0 and 2³²-1 included.

Example

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