If the mouse may not have moved, you can use the mouseenter to get the initial coordinates, then keep updating the coordinates with onmousemove as you are already doing.

var x = null;
var y = null;

document.addEventListener('mousemove', onMouseUpdate, false);
document.addEventListener('mouseenter', onMouseUpdate, false);

function onMouseUpdate(e) {
    x = e.pageX;
    y = e.pageY;
}

This event triggers the page load, so even if the mouse does not move, the coordinates are already available in the x and y variables.
