获取鼠标指针相对于元素的 x 和 y 位置

Question

Hi can anyone help with this?
When I move the mouse pointer of a element, I would like to retrieve the x and y positions relative to the <div>

Eg - when I put the mouse pointer at the top left point of the div I would expect to get an X of 1 and a Y of 1.

This needs to be compatible for Internet Explorer

Thanks all for your time.

This works, trouble was I was calling it from the onclick event which didnt give the scrollLeft and scrollTop values. I should be able to get the position from this by using the calculations of the Divs top and left values.

function getMouseXY(ctrl)        
{
    var tempX = event.clientX + document.body.scrollLeft;
    var tempY = event.clientY + document.body.scrollTop;

    document.getElementById('<%=txtXPos.ClientID%>').value = tempX;
    document.getElementById('<%=txtXPos.ClientID%>').value = tempY;
}

Thanks to all except LincolnK ! ! lol

It's work for me:

function getOffset( el ) 
{
    var _x = 0;
    var _y = 0;
    while( el && !isNaN( el.offsetLeft ) && !isNaN( el.offsetTop ) ) 
    {
        _x += el.offsetLeft - el.scrollLeft;
        _y += el.offsetTop - el.scrollTop;
        el = el.offsetParent;
    }
    return { top: _y, left: _x };
}
var x = getOffset( document.getElementById('MY DIV ID') ).left;
var Y = getOffset( document.getElementById('MY DIV ID') ).top;

function myOnYourEvent()
{
    var relativeX = window.event.clientX;
    var relativeY = window.event.clientY;
    var my_div_x = relativeX - x;
    var my_div_y = relativeY - Y;
    alert(my_div_x  + " " + my_div_y);
}

You could try something like this

function myOnMouseMove(element) {
  var e = window.event
  var relativeX = e.screenX - element.scrollLeft;
  var relativeY = e.screenY - element.scrollTop;
}
