The pointerId
read-only property of the PointerEvent
interface is an identifier assigned to a given pointer event. The identifier is unique, being different from the identifiers of all other active pointer events. Since the value may be randomly generated, it is not guaranteed to convey any particular meaning.
Syntax
var id = pointerEvent.pointerId;
Return value
id
- The pointer event's unique identifier number.
Example
The following code snippet compares a previously saved pointerId
with the one of the pointerdown
event that was just fired.
let id; // Let's assume that this is a previously saved pointerId target.addEventListener('pointerdown', function(event) { // Compare previous event's ID that was cached // to current event's ID and handle accordingly if (id === event.pointerId) process_event(event); }, false);
