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.)
function displayData() { var transaction = db.transaction(['rushAlbumList'], "readonly"); var objectStore = transaction.objectStore('rushAlbumList'); objectStore.openCursor().onsuccess = function(event) { var cursor = event.target.result; if(cursor) { var listItem = document.createElement('li'); listItem.innerHTML = cursor.value.albumTitle + ', ' + cursor.value.year; list.appendChild(listItem); console.log(cursor.value); cursor.continue(); } else { console.log('Entries all displayed.'); } }; };
