[jQuery] Vertical Positioning

[jQuery] Vertical Positioning


I have an element in one div, when clicked, I'd like to blindDown()
another element in another div.
No problem so far.
I'd like to set the vertical positioning of the latter element to the
same vertical positioning of the element clicked, before the
blindDown() is executed.
The divs containing the elements are position:relative, so the
vertical positions should be identical.
I can position the latter element using position:absolute; I need a
value for top:value-here.
What would be the jQuery command which would return the vertical
positioning of the first element?
$('element1').positionY() ???
BTW:
$('element1').css('top') returns 'auto'
