The name property of the IDBObjectStore interface indicates the name of this object store.

Note: This feature is available in Web Workers.


var myObjectStoreName =; = myNewName;


A DOMString containing the object store's name.


There are a several exceptions which can occur when you attempt to change an object store's name.

Either the object store has been deleted or the current transaction is not an upgrade transaction; you can only rename indexes during upgrade transactions; that is, when the mode is "versionchange".
The current transaction is not active.
An object store is already using the specified name.


In the following code snippet, we open a read/write transaction on our database and add some data to an object store using add(). After the object store has been created, we log to the console. For a full working example, see our To-do Notifications app (view example live.)

// Let us open our database
var DBOpenRequest ="toDoList", 4);

DBOpenRequest.onsuccess = function(event) {
  note.innerHTML += '<li>Database initialised.</li>';
  // store the result of opening the database in the db variable. This is used a lot below
  db = DBOpenRequest.result;
  // Run the addData() function to add the data to the database

function addData() {
  // Create a new object ready to insert into the IDB
  var newItem = [ { taskTitle: "Walk dog", hours: 19, minutes: 30, day: 24, month: "December", year: 2013, notified: "no" } ];

  // open a read/write db transaction, ready for adding the data
  var transaction = db.transaction(["toDoList"], "readwrite");

  // report on the success of opening the transaction
  transaction.oncomplete = function(event) {
    note.innerHTML += '<li>Transaction completed: database modification finished.</li>';

  transaction.onerror = function(event) {
  note.innerHTML += '<li>Transaction not opened due to error. Duplicate items not allowed.</li>';

  // create an object store on the transaction
  var objectStore = transaction.objectStore("toDoList");

  // add our newItem object to the object store
  var objectStoreRequest = objectStore.add(newItem[0]);

  objectStoreRequest.onsuccess = function(event) {
    // report the success of our new item going into the database
    note.innerHTML += '<li>New item added to database.</li>';
