jsp 倒计时问题

我这里有个每隔一秒自动刷新一次，然后自加。我想要它从10自减到1，就是倒计时。我该怎么做？请高手指点指点？
<%!
int i=0;
%>
<BR>
<HR>
<font color="#add8e6" size="5">
<%
i++;
response.setHeader("refresh","1");

%>

Answer 1

这里有个js的倒计时程序
参考一下吧

<table name=agree border="0" cellpadding="10" cellspacing="0" align=center width="80%">
<tr align=center>
<td width="50%" align="right">
<FORM name=register method=post action=reg_shang.ASP?action=yes>
<input type="hidden" name="action" value="agree"><INPUT class="go-wenbenkuang" type=submit value=" 同意注册 " name=Submit>
</FORM>
</td>
<td width="50%" align="left">
<FORM action=index.asp method=post><INPUT class=go-wenbenkuang type=submit value=" 我不同意 "></FORM></td>
</tr>
</table>

<SCRIPT>
secs = 10; // Number of secs to delay -CHINA-studio
wait = secs * 1000;
document.forms.register.Submit.disabled =true;
for(i=1;i<=(wait/1000);i++) {
window.setTimeout("doUpdate(" + i + ")", i * 1000);
}
window.setTimeout("Timer()", wait);

function doUpdate(num) {
if(num == (wait/1000)) {
document.forms.register.Submit.value = " 同意注册 ";
} else {
wut = (wait/1000)-num;
document.forms.register.Submit.value = " 同意前先wait (" + wut + ")";
}
}

function Timer() {
document.forms.register.Submit.disabled =false;
}
</SCRIPT>
