var Xm, Ym;
if(window.addEventListener) window.addEventListener("click", mouseClick, false);
else window.document.attachEvent("onclick", mouseClick);
function mouseClick(e){
var o = (e.target) ? e.target : e.srcElement;
Xm = (e.pageX) ? e.pageX : e.clientX;
Ym = (e.pageX) ? e.pageY : e.clientY;
alert(o+"\nAbs: ("+Xm+","+Ym+")"+"\nRel: ("+(Xm-o.offsetLeft)+","+(Ym-o.offsetTop)+")");
}

Try out this too:


document.onclick = function(e){
var curleft = curtop = 0;
var curleft1 = curtop1 = 0;

var e = e ? e : window.event;
var obj = e.target? e.target : e.srcElement;
curleft = obj.offsetLeft
curtop = obj.offsetTop
while (obj = obj.offsetParent) {
curleft += obj.offsetLeft;
curtop += obj.offsetTop;
}
alert('It\'s an anchor\r\nX = ' + curleft + '\r\nY=' + curtop);
}

You could also use the image input element in a form and get the clicked cooridinates as a result of the submitted form if that fits your plan.

form:
<form action="next.php" method="post"...>
<input type="image" name="clickimg">
...
</form>

On next.php:
<?php
echo $_POST['clickimg_y'];
echo " - "; //just to seperate
echo $_POST['clickimg_x'];
?>
