IDBCursor: request property

The request read-only property of the IDBCursor interface returns the IDBRequest used to obtain the cursor.

Note: This feature is available in Web Workers

Value

An IDBRequest object instance.

Examples

When you open a cursor, the request property is then available on that cursor object, to tell you what request object the cursor originated from. For example:

js

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

  const request = objectStore.openCursor();

  request.onsuccess = (event) => {
    const cursor = event.target.result;
    if (cursor) {
      const listItem = document.createElement("li");
      listItem.textContent = `${cursor.value.albumTitle}, ${cursor.value.year}`;
      list.appendChild(listItem);
      console.log(cursor.request);
      cursor.continue();
    } else {
      console.log("Entries all displayed.");
    }
  };
}
