The getAllKeys() method of the IDBIndex interface asynchronously retrieves the primary keys of all objects inside the index, setting them as the result of the request object.

Syntax

getAllKeys()
getAllKeys(query)
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.

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:

TransactionInactiveError DOMException: Thrown if this IDBIndex's transaction is inactive.
InvalidStateError DOMException: Thrown if the IDBIndex has been deleted or removed.

A TypeError exception is thrown if the count parameter is not between 0 and 2^32 - 1 included.

Examples

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