为何将这段代码保存为HTML格式的无法打开内容呢？请哪位专家指点一下啊！

<html>
<head>
<script language="javascript">
var msg="这是一个跑马灯效果的JavaScript文档";
var interval=100;
var spacelen=120;
var space10=" ";
var seq=0;
function Scroll(){
len=msg.length;
window.status=msg.substring(0,seq+1);
seq++;
if(seq>=len){
seq=spacelen;
window.setTimeout("Scroll2();",interval);
}
else
window.setTimeout("Scroll()",interval);
}
function Scorll2(){
var out="";
for(i=1;i<=spacelen/space10.length;i++)out +=space10;
out=out+msg;
len=out.length;
window.status=out.substring(seq,len);
seq++;
if(seq>=len){seq=0;};
window.setTimeout("Scorll2();",interval);
}
Scroll();
</script>
</head>
</html>
