                <label for="rblTitle_0">Mr</label>

            <td>
                <input type="radio" value="Mrs" name="rblTitle" id="rblTitle_1">

            </td>
        </tr>
    </tbody>
</table>

因此，要获取所选的单选按钮值，请在页面中使用以下javaScript代码。

Now you have to work on this code in client-side using jQuery.

<script type="text/javascript">

（document）.ready（function（）{

var rblTitle =

(document).ready(function () { // Get the Radio Buttons. var rblTitle =

（'＃rblTitle'）。find（'input：radio'）;

rblTitle.click（function（）{
//获取所选值
alert（

('#rblTitle').find('input:radio'); rblTitle.click(function () { // Get the selected value alert(
