Sometimes I need get offset top and left, I need do:

var offset = $(...).offset();

alert(offset.top);

alert(offset.left);

But it is strange, maybe I can do, simply:

alert($(...).top());

alert($(...).left());

It can help to get offset or relative position, or set.

$(...).top(50); // eq. .css('top', 50);

A boolean can represents "get relative":

alert($(...).top(true)); // eq. $(...).position().top

Bye.
