秒表在本机测试可以正常，，但是通过局域网，用另一台电脑访问这个页面，秒表变慢了，慢了两秒钟
就是本机页面的秒表正常 走2秒，通过局域网另一台电脑打开相同的页面上秒表 才走1秒
这是什么问题呢，谢谢各位gg、jj --------------------编程问答-------------------- 用 Timer 处发一次算一秒。是不会准确的。Timer1_Tick中 你应该计算两个 datetime 的间隔。才是真正页面停留时间。用ViewState["StartTime"] 记录第一次时间。每次Timer1_Tick中用 datetime.now,和ViewState["StartTime"] 记算间隔 --------------------编程问答-------------------- 可以用javascript实现：
<script type="text/javascript">
function showTime()
{
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
h = check(h);
s = check(s);
document.getElementById("mydiv").innerHTML = "Now,time is " + h + ":" + m + ":" + s;
t = setTimeout("showTime()",500);
}
function check(n)
{
if( n < 10 )
{
n = "0" + n;
}
return n;
}
</script>
--------------------编程问答--------------------
用这个 应该能实现 --------------------编程问答-------------------- 1 不要用服务器端来用秒表，浏览器请求，服务器响应本来就要时间，然后解析、反馈时间肯定不准确，而且你更新得靠浏览器来刷新。
2 建议使用js在客户端自己使用秒表
