Question

<asp:HiddenField ID="email_value" OnChanged="mail()" runat="server" />怎么在cs获得函数的bool类型值

function mail() {
var em = myform.email.value;
var pattern = /^[\da-zA-Z]+(_|)[\da-zA-Z]+@[\da-zA-Z]+.[a-z]+$/;
flag = pattern.test(em);
if (flag) {
document.write("输入的电子邮件格式不正确！");
email.ForeColor = System.Drawing.Color.Red;
return false;
}
else
return true;
}

后台报错
bool v = Request.Form["email_value.OnChange"];
刚刚学网页，做大作业，拜托详细一点~

首先,JS赋值跟runat="server"不起冲突的,你完全可以用个并用JS赋值..其次,不加runat="server"的话,后台就用Request对象的Forms或者QueryStrings集合来获取
