Querying the scrollbar positions of a window
// Return the current scrollbar offsets as the x and y properties of an object
function getScrollOffsets(w) {
// Use the specified window or the current window if no argument
w = w || window;
// This works for all browsers except IE versions 8 and before
if (w.pageXOffset != null) return {x: w.pageXOffset, y:w.pageYOffset};
// For IE (or any browser) in Standards mode
var d = w.document;
if (document.compatMode == "CSS1Compat") return {x:d.documentElement.scrollLeft, y:d.documentElement.scrollTop};
// For browsers in Quirks mode
