var eve=eve||window.event;
var keycode=eve.keyCode;
var mysp=document.getElementById("myspan");
mysp.innerHTML=keycode;
}
function myxy(eve){
var eve=eve||window.event;
var x=eve.x||eve.pageX;
var y=eve.y||eve.pageY;
var loc=x+":"+y;
var mys=document.getElementById("myspan01");
mys.innerHTML=loc;
}
</script>
<style type="text/css">
#mydiv{
border: solid 1px;
width: 200px;
