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