如何使用jquery表单验证插件在单选按钮组上添加表单验证

<script src="jquery.min.js"></script>
<script src="jquery.validate.min.js"></script>

<form id="myForm">
  <input type="radio" name="gender" value="male"> Male
  <input type="radio" name="gender" value="female"> Female
</form>

$(document).ready(function() {
  $("#myForm").validate();
});

$(document).ready(function() {
  $("#myForm").validate({
    rules: {
      gender: {
        required: true
      }
    },
    messages: {
      gender: {
        required: "Please select your gender."
      }
    }
  });
});

$(document).ready(function() {
  $("#myForm").validate({
    // 省略其他配置
  });

  $("#submitButton").click(function() {
    if ($("#myForm").valid()) {
      // 表单通过验证，执行相应的操作
    }
  });
});
