find elements that are stacked under (visually) an element in jquery

Question

if i have 2 divs (z index is not assigned), one layered over the over, can i use the reference to the top div to find which div is below it?

as far as the DOM struct

Answer 1

Check if box1 is sharing the same position as a certain spot on the page.

And only because I'm a little bored, I made this awesome-er

function GetAllElementsAt(x, y) {
    var $elements = $("body *").map(function() {
        var $this = $(this);
        var offset = $this.offset();
        var l = offset.left;
        var t = offset.top;
        var h = $this.height();
        var w = $this.width();

        var maxx = l + w;
        var maxy = t + h;

        return (y <= maxy && y >= t) && (x <= maxx && x >= l) ? $this : null;
    });

    return $elements;
}
