getAllKeys method

IDBRequest getAllKeys([
  1. JSAny? query,
  2. int count
])

The getAllKeys() method of the IDBObjectStore interface returns an IDBRequest object retrieves record keys for all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.

If a value is successfully found, then a structured clone of it is created and set as the result of the request object.

This method produces the same result for:

  • a record that doesn't exist in the database
  • a record that has an undefined value

To tell these situations apart, you need to call the IDBObjectStore.openCursor method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.

Implementation

external IDBRequest getAllKeys([
  JSAny? query,
  int count,
]);
