Question

我有一个asp.net MVC 3 razor视图，它会生成如下所示的复选框：

 @foreach (LoanQuestionIncludesStatement statement in item.Statements)
                {
                    _question = statement.Question;                  
                    @Html.RadioButton("_Q_" + counter.ToString("0#") + _question.ToString(), false, new { @class = "answer " + qOrderedClass, id = "_Q_" + questionOrderedNumber }) @statement.Statement
                    @Html.Hidden("_S_" + counter.ToString("0#") + _question.ToString(), statement.KeyOrStatement) 
                    <br />
                    counter++;
                }

这是生成的html：

我想确保在一组中只检查一个未发生的单选按钮
我想检查控制器动作检查哪个radiobutton，我该怎么做？

我在控制器操作中使用此代码：

  var questionRequests = from x in Request.Form.AllKeys
                                   where x.StartsWith("_Q_")

Answer 1

如果要确保在一个组中只检查一个单选按钮，则必须为该组中的所有那些单选按钮指定相同名称。

Answer 2

id必须是唯一的，name属性相同才能进行分组

请看这个网址：html radio button

在asp.net mvc 3控制器动作中找到已检查的单选按钮
