IDBFactory.open-obsolete

The original, now obsolete open() method of the IDBFactory object requests opening a connection to a database. The method returns an IDBRequest object immediately, and performs the open operation asynchronously. If the operation is successful, a success event is fired on the request object returned from this method, with its result attribute set to the new IDBDatabase object for the connection.

If an error occurs while the database connection is being opened, then an error event is fired on the request object returned from this method.

Syntax

var request = window.indexedDB.open("toDoList");

Returns

A IDBRequest object on which subsequent events related to this request are fired.

Example

var DBOpenRequest = window.indexedDB.open("toDoList");

DBOpenRequest.onerror = function(event) {
  console.log("Error loading database.");
};
 
DBOpenRequest.onsuccess = function(event) {
  console.log("Database initialised");
    
  // store the result of opening the database in the db variable. This is used a lot later on, for opening transactions and suchlike.
  db = request.result;
};

Parameters

name

The name of the database.
