jquery - Get mouse position on scroll

how can i get the mouse position when i scroll down or scroll up

i tried this

$(document).mousemove(function(event) {
    captureMousePosition(event);
}).scroll(function(event) {
    xMousePos = event.pageX + $(document).scrollLeft();
    yMousePos = event.pageY + $(document).scrollTop();
    window.status = "x = " + xMousePos + " y = " + yMousePos;
});

function captureMousePosition(event){
    xMousePos = event.pageX;
    yMousePos = event.pageY;
    window.status = "x = " + xMousePos + " y = " + yMousePos;
}

but didnt worked i want the exact position of mouse relative to the top of page not in respect to window(frame)

we cannot get mouse current position on scroll we can just get how much it scrolled relative to last position so changed it to :

var xMousePos = 0;
var yMousePos = 0;
var lastScrolledLeft = 0;
var lastScrolledTop = 0;

$(document).mousemove(function(event) {
    captureMousePosition(event);
})  

    $(window).scroll(function(event) {
        if(lastScrolledLeft != $(document).scrollLeft()){
            xMousePos -= lastScrolledLeft;
            lastScrolledLeft = $(document).scrollLeft();
            xMousePos += lastScrolledLeft;
        }
        if(lastScrolledTop != $(document).scrollTop()){
            yMousePos -= lastScrolledTop;
            lastScrolledTop = $(document).scrollTop();
            yMousePos += lastScrolledTop;
        }
        window.status = "x = " + xMousePos + " y = " + yMousePos;
    });
function captureMousePosition(event){
    xMousePos = event.pageX;
    yMousePos = event.pageY;
    window.status = "x = " + xMousePos + " y = " + yMousePos;
}

it worked and is working on multi browsers....

anyways thanks all :)
