在.NET中我写了一个javascript给label赋值，但在服务器端获不到值
<script language= "javascript ">
function RadClick()
{
if(document.Form1.Aregg1.checked)
{
document.all.LabAccIdeaState1.innerText = "1 ";
return;
}
if(document.Form1.ArgeeNo1.checked)
{
document.all.LabAccIdeaState1.innerText = "2 ";
return;
}
}
</script>
<form id= "Form1 " name= "Form1 " method= "post " runat= "server ">
<input id=Argee1 onclick=RadClick() type=radio value=1 name=Aregg1 checked> 同意
<input id=ArgeeNo1 onClick() type=radio value=2 name=Aregg1> 不同意
<input type=button value= "添加 " runat=server id=ButAdd>
</form>

为什么我在点不同意后，在界面上javascript 是给label赋值为2，但我在.net后面获不到值？？？不知道为什么，请大家帮我看看！！！

[解决办法]
服务器端是放在ViewState里的，js不能操作ViewState，所以不行
呢可以放在隐藏表单里面
[解决办法]
你这样是取不到的,要么做为参数传,要么放到隐藏域里然后再取

<script language= "javascript ">
function RadClick()
{
if(document.Form1.Aregg1.checked)
{
document.all.LabAccIdeaState1.innerText = "1 ";
document.all.hdnVal.innerText = "1 ";
return;
}
if(document.Form1.ArgeeNo1.checked)
{
document.all.LabAccIdeaState1.innerText = "2 ";
document.all.hdnVal.innerText = "1 ";
return;
}
}
</script>
<form id= "Form1 " name= "Form1 " method= "post " runat= "server ">
<input id=Argee1 onclick=RadClick() type=radio value=1 name=Aregg1 checked> 同意
<input id=ArgeeNo1 onClick() type=radio value=2 name=Aregg1> 不同意
<input type=button value= "添加 " runat=server id=ButAdd>
<input type= "hidden " value= " " runat= "server " id= "hdnVal " >
</form>

.cs中
string val = hdnVal.value;
