W3C Working Draft
A unique identifier for the pointer causing the event
Property of dom/PointerEvent
Note: This property is read-only.
var result = event.pointerId;
Returns an object of type Number.
Needs Examples: This section should include examples.
This identifier must be unique from all other active pointers at the time. A user agent may recycle previously retired values for pointerId from previous active pointers, if necessary.
If the device producing the event is a mouse, then the pointerId must be 1. Device types other than mouse must not have a pointerId of 1.
