Question

This is working : http://jsfiddle.net/9NDXF/1/ when I write onmousemove, but this is not : http://jsfiddle.net/9NDXF/7/ when I write onscroll.

How can I have the mouse position onscroll ?

Answer 1

Because the scroll event has no pageX property. Scrolls suck. Here’s a nice article on mouse scroll events, and a jsFiddle of the demo.

The only way to “get the mouse position on scroll” is to have recorded it at some earlier time, then access it when needed. I would put a lot of thought into why you think this is a good idea first though: jsFiddle

var mousePostion = {clientX:0,clientY:0};

function record(e)
{
    mousePostion = {
        clientX: e.clientX,
        clientY: e.clientY
    };
}
function print(e)
{
   document.getElementById("x").value=mousePostion.clientX;
   document.getElementById("y").value=mousePostion.clientY;
}
window.onmousemove=record;
window.onscroll=print;​
