    The continue() method of the IDBCursor interface advances the cursor to the next position along its direction, to the item whose key matches the optional key parameter. If no key is specified, the cursor advances to the immediate next position, based on the its direction.




    The key to position the cursor at.


    This method may raise a DOMException with a DOMError of one of the following types:

    Exception Description
    TransactionInactiveError This IDBCursor's transaction is inactive.

    The key parameter may have any of the following conditions:

    • The key is not a valid key.
    • The key is less than or equal to this cursor's position and the cursor's direction is next or nextunique.
    • The key is greater than or equal to this cursor's position and this cursor's direction is prev or prevunique.
    InvalidStateError The cursor is currently being iterated or has iterated past its end.


    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. 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 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 =;
        if(cursor) {
          var listItem = document.createElement('li');
          listItem.innerHTML = cursor.value.albumTitle + ', ' + cursor.value.year;
        } else {
          console.log('Entries all displayed.');
