问题描述

大家好，

我的应用程序中有一个简单的客户端计算.
情况就像，

我有3个文本框.说txt1，txt2，txt3.
txt3 = txt1 + txt2

我的javascript工作正常，就像

HI All,

I have a simple client side calculation in my application.
Situation is like,

I have 3 textboxes. Say txt1,txt2,txt3.
txt3 = txt1 + txt2

my javascript works fine which is something like

document.getElementbyID('<%=txt3.ClientID%>').value = Number(document.getElementbyID('<%=txt1.ClientID%>').value) + Number(document.getElementbyID('<%=txt2.ClientID%>').value);

我在客户端得到结果.但是，当我在服务器端代码中编写txt3.text时，我什么也没得到.

txt3是只读的，我试图将其设置为readonly，但工作正常，但如何将其设置为true呢?

请有人可以帮助我....

在此先感谢您.

I get result on client side. But when i write txt3.text in server side code i get nothing.

txt3 is readonly i tried to make it readonly false and it worked fine but how can I make it with readonly true?

Please some one can help me....

Thanks in advance.

function doIt()
