<!DOCTYPE html>
<html>
<body>
<p onclick = "coordsFunc(event)">

coordinates of the mouse pointer.
</p>
<script>
function coordsFunc(event) {
var x_coord = event.pageX;
var y_coord = event.pageY;
var xycoords = "X coords= " + x_coord + ", Y coords= " + y_coord;
document.write(xycoords);
}
</script>
</body>
