The previous object.
There are no standards that apply here.
You can use the IDOMMouseEvent::fromElement property for HTMLFrameSiteEvents::onmouseenter, HTMLFrameSiteEvents::onmouseleave, HTMLFrameSiteEvents::onmouseover, and HTMLFrameSiteEvents::onmouseout events. For example, during an HTMLFrameSiteEvents::onmouseover event, the IDOMMouseEvent::fromElement property gets the element that the mouse pointer has exited, and the IDOMMouseEvent::toElement property gets the element that the mouse pointer has entered.
You can also use the IDOMMouseEvent::relatedTarget event property to indicate the previous object in mouse transition events. In general, the IDOMEvent::target attribute always refers to the object that raised an event.
