If I understood you correctly you need to find out the element over the mouse is currently on. If this is correct you can use

document.elementFromPoint ( x, y );

document.elementFromPoint

Returns the element from the document whose elementFromPoint method is being called which is the topmost element which lies under the given point. The point is specified via coordinates, in CSS pixels, relative to the upper-left-most point in the window or frame containing the document.

$(document).ready(function(){
   $(this).mousemove(function(e){
      var elem = document.elementFromPoint ( e.pageX , e.pageY );
    alert ( elem.id );
   }); 
})
