IDBDatabase.close();

Properties

None.

Return value

Void.

Example

// Let us open our database
  var DBOpenRequest = window.indexedDB.open("toDoList", 4);
  // Create event handlers for both success and failure of
  // opening a database.
  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.
    db = DBOpenRequest.result;
    // now let's close the database again!
    db.close();
  }
