Question

我的asp.net设计编码如下：

<table>
<tr>
<td>
    <asp:RadioButton ID="rad" runat="server" />
</td>
</tr>
<tr>
<td>
    <asp:RadioButton ID="RadioButton1" runat="server" />
</td>
</tr>
<tr>
<td>
    <asp:RadioButton ID="RadioButton2" runat="server" />
</td>
</tr>
</table>

当我运行这个时，我能够选择所有单选按钮..但我只想选择一个......怎么做...？

Answer 1

像这样分配GroupName属性：

<asp:RadioButton ID="RadioButton1" runat="server" GroupName="Category1" />
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="Category1" />
<asp:RadioButton ID="RadioButton3" runat="server" GroupName="Category1" />

我没有测试过这个，但它应该可行。还有一个RadioButtonList控件，您可能需要查看http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.radiobuttonlist(v=vs.110).aspx

有关基本控件的详细信息，请查看单选按钮上的w3c文档：http://www.w3.org/TR/html401/interact/forms.html#radio

Answer 2

$("#<%RadioButton1.ClientID%>").change(function(){//server control so use ClientID
    //when RadioButton1 will change this will fire
});

Answer 3

你应该为你的单选按钮添加GroupName .. !!

 <table>
<tr>
<td>
    <asp:RadioButton ID="rad" GroupName="Radio" runat="server" />
</td>
</tr>
<tr>
<td>
    <asp:RadioButton ID="RadioButton1" GroupName="Radio" runat="server" />
</td>
</tr>
<tr>
<td>
    <asp:RadioButton ID="RadioButton2" GroupName="Radio" runat="server" />
</td>
</tr>
</table>

想要从列表中只选择一个单选按钮
