IDBCursorWithValue: value property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

Note: This feature is available in Web Workers.

The value read-only property of the IDBCursorWithValue interface returns the value of the current cursor, whatever that is.

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() {   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.");     }   }; }
