    The IDBEnvironment interface of the IndexedDB API contains the indexedDB property, which provides access to IndexedDB functionality. It is the top level IndexedDB interface implemented by the window and Worker objects.


    IDBEnvironment.indexedDB Read only
    Provides a mechanism for applications to asynchronously access capabilities of indexed databases; contains an IDBFactory object.


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

    var db;
    function openDB() {
     var DBOpenRequest ="toDoList");
     DBOpenRequest.onsuccess = function(e) {
       db = DBOpenRequest.result;

    Be careful in Chrome as it still implements the old specification along with the new one. Similarly it still has the prefixed webkitIndexedDB property even if the unprefixed indexedDB is present.
