IDBIndex: getAllKeys() method

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

js

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.

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 2^32 - 1 a TypeError exception will be thrown.

Return value

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

If the operation is successful, the value of the request's result property is an Array of the keys for all records matching the given query, up to the value of count, if count was supplied.

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

js

const myIndex = objectStore.index("index");
const getAllKeysRequest = myIndex.getAllKeys();
getAllKeysRequest.onsuccess = () => {
  console.log(getAllKeysRequest.result);
};
