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.");
}
};
}
