添加如下代码:

<SCRIPT LANGUAGE="JavaScript">
<!--
function scroll(seed)
{
var m1 = "欢迎光临--"
var m2 = "！"
var msg=m1+m2;
var out = " ";
var c = 1;
if (seed > 100) {
seed--;
var cmd="scroll(" + seed + ")";
timerTwo=window.setTimeout(cmd,100);
}
else if (seed <= 100 && seed > 0) {
for (c=0 ; c < seed ; c++) {
out+=" ";
}
out+=msg;
seed--;
var cmd="scroll(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,100);
}  else if (seed <= 0) {
if (-seed < msg.length) {
out+=msg.substring(-seed,msg.length-100);
seed--;
var cmd="scroll(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,100);
}
else {
window.status=" ";
timerTwo=window.setTimeout("scroll(100)",7);
}
}
}
rONE=window.setTimeout('scroll(100)',50);
