我真的需要帮助，我正在编写验证表格，验证工作正常。我的问题是如何呈现特定于字段和字段旁边的错误？ 现在，如果用户键入了无效的电话和无效的邮件，它会在两个字段（电子邮件和电话）中显示“电话必须是9-10位”。所以我想要的是显示在每个领域中出现的错误。
$('.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;

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进行验证 - 您可以使用以下内容：
<input type=text pattern="[0-9]{9,10}" title="Enter 10 digits phone number" placeholder="phone">
title属性将用作错误消息。

您可以使用此库Confere.js来实现目标！
它现在正处于繁重的发展阶段，但我认为它可以满足您的需求。
对于手机验证，我认为您可以使用min和max规则，也可以使用以下方式实现自己的规则：
Confere.validaor("phone", function(name, value, params, options){
return new Promise(function(resolve, reject){
if(success){ resolve() } //when pass
else{
var error = new Error('Error Message');
error.field = name;
reject(error);
}
});
});
例：
$('.x-contact-form').on('submit', function(e) {
e.preventDefault();
var confere = new Confere({
rules: this
})
confere.validate().then(function() {
//submit your form
}).catch(function(err) {
//remove all errors notifications
Object.keys(confere.options.rules).map(function(key){
$(`.${key}-group`).removeClass('has-error');
$(`.${key}-group`).addClass('has-success');
$(`#${key}_error`).text('');
});
//add errors on fields that failed validation
Object.keys(err.result).map(function(key) {
$(`.${key}-group`).addClass('has-error');
$(`#${key}_error`).text(err.result[key][0].message);
});
});
