HI friends,Try the source below;The javascript i used for automatic calculation;
i want the t1,t2,t3 controls in server side for further coding.
For eg:I want this t3 value to label on button click event;
< html xmlns ="http://www.w3.org/1999/xhtml">
< head runat ="server">
< script type ="text/javascript">
函数nims(){
var a = parseFloat(document.form1.t1.value);
var b = parseFloat(document.form1.t2.value);
var sum = a + b;
document.form1.t3.value = sum;
}
</script>
< title> </title>
</head>
< body>
< form id ="form1" runat ="server">
< input type ="text" value ="0" name ="t1" onkeyup ="nims();" />
< input type ="text" value ="0" name ="t2" onkeyup ="nims();"/>
<输入type ="text" value ="0" name ="t3"/>
</form>
</body>
</html>
<html xmlns="http://www.w3.org/1999/xhtml">

<input type="text" value="0" name="t3" />
</form>
</body>

推荐答案
可以在其中添加runat ="Server"标签吗?
Can you add runat="Server" tag there?
如果要访问服务器端的控件进行任何计算，必须将控件标记为"runat=server".
基于更改，您当然也必须更改Javascript代码.当前的实现基于客户端html控件，但是一旦将runat属性添加到控件中，访问它们的方式就会改变.更改后，使用<%= myControl.ClientID %>在JavaScript中访问客户端上的控件.
If you want to access the controls on the server side for any calculation, you have to mark the controls as ''runat=server''.
Based on the change, you surely have to change the Javascript code too. Current implementation is based on client side html controls, but once you add the runat property to the controls, the way to access them will change. Use<%= myControl.ClientID %>to access the control on client side in JavaScript after the change.
