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. Within each iteration we log the value of the cursor with cursor.value
.
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 cursor.value.foo
. For a complete working example, see our IDBCursor example (view example live.)
js
function displayData() { const transaction = db.transaction(["rushAlbumList"], "readonly"); const objectStore = transaction.objectStore("rushAlbumList"); objectStore.openCursor().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.value); cursor.continue(); } else { console.log("Entries all displayed."); } }; }
