第二の方式ですが、firefoxにはちょっと問題があります.
<html>
<head>
<title> Mark </title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"/>
<script type="text/javascript">
function GetMark()
{

if(eif!=null)
{
document.body.bgColor='black';
eif.style.display="";
}
else
{

e.scrolling="no";
e.frameborder=0;
