Not possible. You can however use the same approach in the tutorial to store the position in a global variable and read it outside the event.
Like this:
jQuery(document).ready(function(){
$().mousemove(function(e){
window.mouseXPos = e.pageX;
window.mouseYPos = e.pageY;
});
})
You can now use window.mouseXPos
and window.mouseYPos
from anywhere.
