An IDBRequest
object instance.
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."); } }; }
