IDBObjectStore: name property

Note: This feature is available in Web Workers.

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

Value

A string 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 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 DOMException: Thrown if the current transaction is not active.
ConstraintError DOMException: Thrown if 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 objectStore.name to the console. For a full working example, see our To-do Notifications app (view example live).

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

DBOpenRequest.onsuccess = (event) => {
 note.appendChild(document.createElement("li")).textContent =
 "Database initialized.";

 // 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
 const 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
 const transaction = db.transaction(["toDoList"], "readwrite");

 // report on the success of the transaction completing, when everything is done
 transaction.oncomplete = (event) => {
 note.appendChild(document.createElement("li")).textContent =
 "Transaction completed.";
 };

 transaction.onerror = (event) => {
 note.appendChild(document.createElement("li")).textContent =
 "Transaction not opened due to error. Duplicate items not allowed.";
 };

 // create an object store on the transaction
 const objectStore = transaction.objectStore("toDoList");
 console.log(objectStore.name);

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

 objectStoreRequest.onsuccess = (event) => {
 // report the success of our request
 note.appendChild(document.createElement("li")).textContent =
 "Request successful.";
 };
}
