asp.net中Label 控件如何获取系统当前时间并自动更新

《body》
《form id="form1" runat="server"》
《div》
《asp:Label ID="lbltime" runat="server" Text="现在时间是："》《/asp:Label》
《asp:TextBox ID="txttime" runat="server"》《/asp:TextBox》
《/div》
《/form》
《script type="text/javascript" language="javascript"》
function show() {
var date = new Date(); //实例化一个时间对象
var year = date.getFullYear(); //获取年
var month = date.getMonth() + 1; //获取月份，因为是0-11.所以我们要加上1
var day = date.getDate();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
document.getElementById("lbltime").innerHTML = year + "年" + month + "月" + day + "日" + " " + hour + ":" + minute + ":" + second;
document.getElementById("txttime").value = year + "年" + month + "月" + day + "日" + " " + hour + ":" + minute + ":" + second;
setTimeout("show()", 1000); //settimeout 是隔多久调用这个函数一次， 1000毫秒就是1秒， 所以看上去就是每秒刷新。
}
show();
《/script》
《/body》
其实大家说的基本上没问题，关键在于你是用Label显示时间（不是通常的TextBox）。
如果是改变Label值，则需用document.getElementById("lbltime").innerHTML，如果用TextBox之类的，则需用document.getElementById("txttime").value 。
所以，针对Label和TextBox显示时间分别为：
document.getElementById("lbltime").innerHTML = year + "年" + month + "月" + day + "日" + " " + hour + ":" + minute + ":" + second;
document.getElementById("txttime").value = year + "年" + month + "月" + day + "日" + " " + hour + ":" + minute + ":" + second;
上述代码已经测试过，如果还有疑问，可以Hi我。

vba 在label中显示即时时间

老大这个没有那么麻烦吧，你直接这样子弄要简单些哦在窗体上面放一个timer，然后把它的interval设为1000,然后放个label，好，现在双击窗体上的timer，然后录入label1.caption=time，好，完了，就这么简单！
