javascript - 为什么单选按钮随着 JQuery 验证而消失？

标签 javascript jquery html css

预先对代码量表示歉意。我想呈现一幅完整的图画。

我的问题:验证表单时(使用 Jquery Validate )，如果用户在发送前未选择单选按钮，则单选按钮会消失。我该如何解决这个问题？

UUUHMM:当我从单选按钮中删除“必需”时，单选按钮不会消失。您可能认为“问题已解决”，但我确实需要在未使用单选按钮时显示一条消息，而这不会发生。

在 Windows 计算机上检查后，我发现在 Windows 计算机上没有显示任何消息。什么？？？我究竟做错了什么!？在 Mac 上显示消息。

autosize(document.querySelectorAll('#message_content'));


var validator = $("#comment_form").validate({
  ignore: [],
  rules: {
    gender: {
      required: true,
    },
    first_name: {
      required: true,
    },
    last_name: {
      required: true,
    },
    email: {
      required: true,
      email: true,
      minlength: 3
    },
    email_again: {
      email: true,
      minlength: 3,
      equalTo: '#email'
    },
    message_subject: {
      required: true,
      minlength: 2
    },
    message: {
      required: true,
      minlength: 4
    },
    hiddenRecaptcha: {
      required: function() {
        if (grecaptcha.getResponse() == '') {
          return true;
        } else {
          return false;
        }
      }
    }
  }
});

最佳答案

您看不到单选按钮的原因是当单选输入有错误时，您将它们指定为“错误”类。你在 css 中告诉 display: none;。如果您删除该类，该元素将按您的预期显示
