pos = pos.split(":");
var posX = pos[0];
var posY = pos[1];
alert(posX + "-" + posY);
}

function getMousePosition(e){
var cur_posX = 0;
var cur_posY = 0;
try{
cur_posX = e.pageX;
cur_posY = e.pageY;
}catch(e){}

try{
var de = document.documentElement;
var b = document.body;
cur_posX = e.clientX +
(de.scrollLeft || b.scrollLeft) - (de.clientLeft || 0);
cur_posY = e.clientY +
(de.scrollTop || b.scrollTop) - (de.clientTop || 0);
}catch(e){}
return cur_posX+":"+cur_posY;
