The IDBCursorWithValue interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database. It is the same as the IDBCursor, except that it includes the value property.

The cursor has a source that indicates which index or object store it is iterating over. It has a position within the range, and moves in a direction that is increasing or decreasing in the order of record keys. The cursor enables an application to asynchronously process all the records in the cursor's range.

You can have an unlimited number of cursors at the same time. You always get the same IDBCursorWithValue object representing a given cursor. Operations are performed on the underlying index or object store.

IDBCursorWithValue.value Read only

Returns the value of the current cursor.


In this example we create a transaction, retrieve an object store, then use a cursor to iterate through all the records in the object store. The cursor does not require us to select the data based on a key; we can just grab all of it. Also note that in each iteration of the loop, you can grab data from the current record under the cursor object using For a complete working example, see our IDBCursor example (view example live.)

function displayData() {
  const transaction = db.transaction(["rushAlbumList"], "readonly");
  const objectStore = transaction.objectStore("rushAlbumList");

  objectStore.openCursor().onsuccess = (event) => {
    const cursor =;
    if (cursor) {
      const listItem = document.createElement("li");
      listItem.textContent = `${cursor.value.albumTitle}, ${cursor.value.year}`;

    } else {
      console.log("Entries all displayed.");
