Getting absolute 'top' position from a mouse event (Javascript/jQuery)

Question

On a mouseenter/mouseleave event, I would like to capture the absolute 'top' position of the cell of a table.

So far, the event is attached like so:

$('td[someAttr]').mouseenter(function(mouse) {
   // how do we get the td's top absolute position?

   //FYI: mouse.pageX and mouse.pageY would give the mouse position
});

Answer 1

$(this).offset().top

Answer 2

$(this).offset().top
