Web/API/IDBCursor/request

The request read-only property of the IDBCursor interface returns the IDBRequest used to obtain the cursor.

Note: This feature is available in Web Workers.

Syntax

var request = cursor.request;

Value

An IDBRequest object instance.

Examples

When you open a cursor, the request property is then available on that cursor object, to tell you what request object the cursor originated from. For example:

function displayData() {
  list.innerHTML = '';
  var transaction = db.transaction(['rushAlbumList'], 'readonly');
  var objectStore = transaction.objectStore('rushAlbumList');

  var request = objectStore.openCursor();

  request.onsuccess = function(event) {
    var cursor = event.target.result;
      if(cursor) {
        var listItem = document.createElement('li');
        listItem.innerHTML = '<strong>' + cursor.value.albumTitle + '</strong>, ' + cursor.value.year;
        list.appendChild(listItem);
        console.log(cursor.request);
        cursor.continue();
      } else {
        console.log('Entries all displayed.');
      }
  };
};
