var v = document.createElement('DIV');
v.style.position = 'absolute';
v.style.left = '0px';
v.style.top = '0px';
v.style.width = '100%';
v.style.height = '100%';
v.style.backgroundColor = 'red';
document.body.appendChild(v);
}show();
</script>
var v = document.createElement('DIV');
v.style.position = 'absolute';
v.style.left = '0px';
v.style.top = '0px';
v.style.width = '100%';
v.style.height = '100%';
v.style.backgroundColor = 'red';
document.body.appendChild(v);
}show();
</script>
