getAll() metodu IDBIndex Arabirimi, dizinin içindeki tüm nesneleri alır.

Nesne tembel olarak oluşturulduğundan, bir imlecin value özelliğine bakmakla ilişkili bir performans maliyeti söz konusudur. GetAll () gibi bir özellik kullanmak için, tarayıcının tüm nesneleri aynı anda oluşturması gerekir. Örneğin sadece anahtarların her birine bakmak istiyorsanız, bir imleci kullanmak daha etkilidir. Ancak, bir nesne deposundaki tüm nesnelerin bir dizisini almaya çalışıyorsanız, getAll () kullanmalısınız.

Syntax

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

Parametreler

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);
}
