The code read-only property of the DOMException interface returns a short that contains one of the error code constants, or 0 if none match. This field is used for historical reasons. New DOM exceptions don't use this anymore: they put this info in the DOMException.name attribute.
var domExceptionCode = domExceptionInstance.code;
A short number.
