MDN
Returns an IDBRequest object, and, in a separate thread, deletes the record at the cursor's position, without changing the cursor's position.
Returns an IDBRequest object, and, in a separate thread, deletes the record at the cursor's position, without changing the cursor's position.
MDN
Is a DOMString that, on getting, returns the direction of traversal of the cursor.
Is a DOMString that, on getting, returns the direction of traversal of the cursor. See Constants for possible values.
MDN
Returns the key for the record at the cursor's position.
Returns the key for the record at the cursor's position. If the cursor is outside its range, this is set to undefined. The cursor's key can be any data type.
MDN
Returns the cursor's current effective key.
Returns the cursor's current effective key. If the cursor is currently being iterated or has iterated outside its range, this is set to undefined. The cursor's primary key can be any data type.
MDN
On getting, this object returns the IDBObjectStore or IDBIndex that the cursor is iterating.
On getting, this object returns the IDBObjectStore or IDBIndex that the cursor is iterating. This function never returns null or throws an exception, even if the cursor is currently being iterated, has iterated past its end, or its transaction is not active.
MDN
Returns an IDBRequest object, and, in a separate thread, updates the value at the current position of the cursor in the object store.
Returns an IDBRequest object, and, in a separate thread, updates the value at the current position of the cursor in the object store.
MDN
The IDBCursor interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database.
The cursor has a source that indicates which index or object store it is iterating. It has a position within the range, and moves in a direction that is increasing or decreasing in the order of record keys. The cursor enables an application to asynchronously process all the records in the cursor's range.
