{{ APIRef("IndexedDB") }}

The **`name`** property of the {{domxref("IDBObjectStore")}}
interface indicates the name of this object store.

{{AvailableInWorkers}}

## Syntax

```js
IDBObjectStore.name = myNewName;
var myObjectStoreName = IDBObjectStore.name;
```

### Value

A {{domxref("DOMString")}} containing the object
store's name.

### Exceptions

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

- `InvalidStateError` {{domxref("DOMException")}}
  - : Thrown if 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`.
- `TransactionInactiveError` {{domxref("DOMException")}}
  - : Thrown if the current transaction is not active.
- `ConstraintError` {{domxref("DOMException")}}
  - : Thrown if an object store is already using the specified `name`.

## Example

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 `objectStore.name` to
the console. For a full working example, see
our [To-do Notifications](https://github.com/mdn/to-do-notifications/) app
(>[view example live](https://mdn.github.io/to-do-notifications/).)

```js
// Let us open our database
var DBOpenRequest = window.indexedDB.open("toDoList", 4);

DBOpenRequest.onsuccess = function(event) {
  note.innerHTML += '<li>Database initialized.</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
  addData();
};

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 the transaction completing, when everything is done
  transaction.oncomplete = function(event) {
    note.innerHTML += '<li>Transaction completed.</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");
  console.log(objectStore.name);

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

  objectStoreRequest.onsuccess = function(event) {
    // report the success of our request
    note.innerHTML += '<li>Request successful.</li>';
  };
};
```
