javascript - 验证jquery问题

Question

我真的需要帮助，我正在处理验证表单，验证正在工作。我的问题是如何呈现特定于该字段和该字段旁边的错误？ 现在，如果用户输入无效的电话和无效的邮件，则会在两个字段(电子邮件和电话)中显示“电话必须是 9-10 位数字”。所以我想要的是在每个字段中显示与该字段相关的错误。

$('.xone-contact').submit(function() {
  var $form = $(this);
  var $form1 = $(this);
  var $form2 = $(this);
  var submitData = $form.serialize();
  var $phone = $form1.find('input[name="phone"]');
  var $email = $form2.find('input[name="email"]');
  var $name = $form.find('input[name="name"]');
  var $message = $form.find('textarea[name="message"]');
  var $submit = $form.find('input[name="submit"]');
  var $dataStatus = $form.find('.data-status');
  var $dataStatus1 = $form1.find('.phone_error');
  var $dataStatus2 = $form2.find('.email_error');

  $email.attr('disabled', 'disabled');
  $phone.attr('disabled', 'disabled');
  $name.attr('disabled', 'disabled');
  $message.attr('disabled', 'disabled');
  $submit.attr('disabled', 'disabled');

  $dataStatus.show().html('<div class="alert alert-info"><strong>Loading...</strong></div>');

  $.ajax({ // Send an offer process with AJAX
    type: 'POST',
    url: 'assets/contact_form/process-contact.php',
    data: submitData + '&action=add',
    dataType: 'html',
    success: function(msg) {
      if (parseInt(msg, 0) !== 0) {
        var msg_split = msg.split('|');
        if (msg_split[0] === 'success') {
          $phone.val('').removeAttr('disabled');
          $email.val('').removeAttr('disabled');
          $name.val('').removeAttr('disabled');
          $message.val('').removeAttr('disabled');
          $submit.removeAttr('disabled');
          $dataStatus.html(msg_split[1]).fadeIn();
        } else {
          $phone.removeAttr('disabled');
          $email.removeAttr('disabled');
          $name.removeAttr('disabled');
          $message.removeAttr('disabled');
          $submit.removeAttr('disabled');
          $dataStatus.html(msg_split[1]).fadeIn();
          $dataStatus1.html(msg_split[1]).fadeIn();
          $dataStatus2.html(msg_split[1]).fadeIn();
        }
      }
    }
  });

  return false;
});

Answer 1

HTML5 表单输入能够自行检查模式，因此无需将它们发送到服务器来验证它 - 您可以使用如下内容:

<input type=text pattern="[0-9]{9,10}" title="Enter 10 digits phone number" placeholder="phone">

title 属性在输入不正确时用作错误消息。
