IDBCursorWithValue.value

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

Note: This feature is available in Web Workers.

Syntax

JavaScript
cursor.value;

Value

The value of the current cursor.

Example

In this simple fragment 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.)

JavaScript
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.');
    }
  };
};
