Example

The following code creates a request for a database to be opened asynchronously, after which the database is opened when the request's onsuccess handler is fired:

function openDB() {
 var DBOpenRequest = window.indexedDB.open('toDoList');
 DBOpenRequest.onsuccess = function(e) {
   db = DBOpenRequest.result;
 }
}
