document.body.onmousemove = function(e)
{

  var mleft = event.pageX || event.clientX;
  var mtop = event.pageY || event.clientY;
  document.getElementById("info").style.top = mtop + "px";
}
</script>

  $("html").mousemove(function(event){
     var mleft = event.pageX;
     var mtop = event.pageY;
     $("#info").text(mleft+", "+mtop);
  });
});
</script>

        var thisPosX = $(this).position().left;
        var thisPosY = $(this).position().top;
      
      
        msg = (event.clientX-thisPosX) + ", " + (event.clientY-thisPosY);
