如何检查多个单选按钮选择？ [英] How to check for multiple radio button selections?

问题描述

我有一个问题表单，我想用jQuery进行验证。我的表单看起来像这样：

I have a question form that I want to validate using jquery. My form looks like this:

       <form id="question_answer_form" action="submit_answers.php" method="post">       
            <table class="zebra-striped">
                <tr>
                    <td >Question 1</td>

                    <td>
                        <input type="radio" name="question_answer1" value="1"> Yes
                        <input type="radio" name="question_answer1" value="0"> No
                    </td>
                </tr>
                <tr>
                    <td >Question 2</td>
                    <td>
                        <input type="radio" name="question_answer2" value="1"> Yes
                        <input type="radio" name="question_answer2" value="0"> No
                    </td>
                </tr>
                <tr>
                  <td >Question 3</td>
                    <td>
                        <input type="radio" name="question_answer3" value="1"> Yes
                        <input type="radio" name="question_answer3" value="0"> No
                    </td>
                </tr>
                <tr>
                   <td colspan="2"><input class="btn success" type="button" value="Submit" id="questions"/></td>
                </tr>
            </table>
       </form>

Jquery调用

    $("#questions").click(function (e) {
        e.preventDefault();

        // Check radio button status and notify...;
    });

有何建议？

Any suggestions?
