我查了很多资料写了一个秒杀用户自定义控件，先是获取不到服务器时间，我费了九牛二虎之力之后，可以获取到服务器时间，但倒计时不走了。哎……，帮我看一下吧。
<script language="JavaScript" type="text/javascript">

function showTimeLimit<%=this.ClientID %>(str, end, now) {
var now = new Date(now);
前台：
var future = new Date(str);
future -= 1000;
if (now - future < 0) {
var days = (future - now) / 1000 / 60 / 60 / 24;
var dayNum = Math.floor(days);
var hours = (future - now) / 1000 / 60 / 60 - (24 * dayNum);
var houNum = Math.floor(hours);
if (houNum < 10) {
houNum = "0" + houNum;
}
var minutes = (future - now) / 1000 / 60 - (24 * 60 * dayNum) - (60 * houNum);
var minNum = Math.floor(minutes);
if (minNum < 10) {
minNum = "0" + minNum;
}
var seconds = (future - now) / 1000 - (24 * 60 * 60 * dayNum) - (60 * 60 * houNum) - (60 * minNum);
var secNum = Math.floor(seconds);
if (secNum < 10) {
secNum = "0" + secNum;
}
document.getElementById('TimeLimit1<%=this.ClientID %>').innerHTML = "距秒杀开始还有: " + dayNum + "天" + houNum + "小时" + minNum + "分" + secNum + "秒";
}

else {
var future = new Date(end);
if (now - future < 0) {
var days = (future - now) / 1000 / 60 / 60 / 24;
var dayNum = Math.floor(days);
var hours = (future - now) / 1000 / 60 / 60 - (24 * dayNum);
var houNum = Math.floor(hours);
if (houNum < 10) {
houNum = "0" + houNum;
}
var minutes = (future - now) / 1000 / 60 - (24 * 60 * dayNum) - (60 * houNum);
var minNum = Math.floor(minutes);
if (minNum < 10) {
minNum = "0" + minNum;
}
var seconds = (future - now) / 1000 - (24 * 60 * 60 * dayNum) - (60 * 60 * houNum) - (60 * minNum);
var secNum = Math.floor(seconds);
if (secNum < 10) {
secNum = "0" + secNum;
}
document.getElementById('TimeLimit1<%=this.ClientID %>').innerHTML = "距秒杀结束还有: " + dayNum + "天" + houNum + "小时" + minNum + "分" + secNum + "秒";
}
else {
document.getElementById('TimeLimit1<%=this.ClientID %>').innerHTML = "秒杀已结束";

}
}
}

</script>
">请稍等，正在载入中。。。
<asp:Literal runat="server" ID="lblTime1"></asp:Literal>

后台：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication7
{
public partial class Seckill : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.lblTime1.Text = "<script language=\"javascript\" type=\"text/javascript\">setInterval('showTimeLimit" + this.ClientID + "(\"" + StartSeckill + "\",\"" + EndSeckill + "\",\"" + System.DateTime.Now + "\")', 1000);</script>";

}
public DateTime StartSeckill
{
get
{
EnsureChildControls();
return (DateTime)(ViewState["start time"] ?? DateTime.Now);
}
set
{
EnsureChildControls();
ViewState["start time"] = value;
}
}
public DateTime EndSeckill
{
get
{
EnsureChildControls();
return (DateTime)(ViewState["end time"] ?? DateTime.Now);
}
set
{
EnsureChildControls();
ViewState["end time"] = value;
}
}
}
}
