IDBIndex.getAll()

The getAll() method of the IDBIndex interface retrieves all objects that are inside the index.

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(), the browser has to create all the objects at once. If you are just interested in looking at each of the keys, for instance, it is more efficient to use a cursor. If you are trying to get an array of all the objects in an object store, though, you should use getAll().

Syntax

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

Parameters

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. 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 getAllKeysRequest = myIndex.getAllKeys();
getAllKeysRequest.onsuccess = function() {
  console.log(getAllKeysRequest.result);
}
