el.getAttribute("id") vs. el.id #748

Closed loesler closed 1 month ago

If an element el does not have an id, el.id returns an (empty) string but el.getAttribute("id") returns null (at least in Opera), cf. #741 A condition has been added to catch errors (when using image or code without any attribute).
