{{APIRef("IndexedDB")}}

+ +
+

A interface IDBFactory, pertencente a IndexedDB API , permite que aplicativos acessem de forma assíncrona os bancos de dados indexados. O objeto que implementa a interface é o window.indexedDB, com este objeto é possível criar, acessar, modificar e excluir informações de um banco de dados.

Métodos

+ +
+
{{domxref("IDBFactory.open")}}
+
Realizar a abertura de uma conexão com uma base de dados.
+
{{domxref("IDBFactory.deleteDatabase")}}
+
Remove uma base de dados.
+
{{domxref("IDBFactory.cmp")}}
+
Compara dois valores chaves e determina se elas são iguais e se não, quem é a maior.
+
+ +

Métodos Obsoletos

+ +
+
IDBFactory.open, a versão original {{ obsolete_inline }}
+
Este método realizava conexão com uma base de dados, ele ainda é usado em alguns navegadores.
+
+ +

Exemplo

+ +

No código abaixo, realizamos uma conexão com um banco de dados e incluímos manipuladores para os casos de sucesso e erro. Você pode obter o To-do Notifications app como exemplo (Visualizar exemplo.)

+ +
var note = document.querySelector("ul");
+
+// In the following line, you should include the prefixes of implementations you want to test.
+window.indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB;
+// DON'T use "var indexedDB = ..." if you're not in a function.
+// Moreover, you may need references to some window.IDB* objects:
+window.IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction || window.msIDBTransaction;
+window.IDBKeyRange = window.IDBKeyRange || window.webkitIDBKeyRange || window.msIDBKeyRange;
+// (Mozilla has never prefixed these objects, so we don't need window.mozIDB*)
+
+// Let us open version 4 of our database
+var DBOpenRequest = window.indexedDB.open("toDoList", 4);
+
+// these two event handlers act on the database being opened successfully, or not
+DBOpenRequest.onerror = function(event) {
+  note.innerHTML += '<li>Error loading database.</li>';
+};
+
+DBOpenRequest.onsuccess = function(event) {
+  note.innerHTML += '<li>Database initialised.</li>';
+
+  // store the result of opening the database in the db variable. This is used a lot later on, for opening transactions and suchlike.
+  db = DBOpenRequest.result;
+};
+
+ +
