jquery 验证错误多个字段 1 个自定义错误消息

Question

我在 Stack 上四处寻找，试图找到解决我在 jQuery 验证中遇到的问题的方法。我决定将输入字段下方的错误消息更改为放置在表单上方的单个通用全包消息。我在那条消息 "#error_mail" 上有一个 class "hide" 我想用"error" 当 submission/validation 的字段中出现错误时。任何帮助将不胜感激，提前致谢。

HTML

<form action="#" method="post" class="new_web_user" id="new_web_user" autocomplete="off">
            <p class="fields-required">
            *Required fields</p>
            <p id="error_mail" class="hide">We&#39;re sorry, the fields highlighted in red are required</p>
            <div class="field-column"> etc etc.....

JS

$(function(){jQuery.validator.setDefaults({
             errorContainer: "#error_mail",
             errorPlacement: function(error, element) {
             error.appendTo('#error_mail');
      },
             ignore: ':hidden:not([class~=selectized]),:hidden > .selectized, .selectize-control .selectize-input input'
      });

    $('#new_web_user').validate({
              rules: {
                  web_user_title: {required: true},
                  web_user_given_name: {
                    required: true
                 },
                  web_user_family_name: {
                    required: true
                 },                  
                  web_user_email: { 
                    required:   true,
                    email:      true
                 },
                 email_confirmation: {
                    required:   true,
                      equalTo: '#web_user_email'
                 },
                 web_user_country: {
                    required:   false,
                 },
              },
              messages : {
                 web_user_title:     {
                        required: "Please select a title."
                 },
                 web_user_given_name:    {
                        required: "Firstname is required."
                 },
                 web_user_family_name:   {
                        required: "Lastname is required."
                 },
                 web_user_email:     {
                        required: "Email address is required.",
                        email: "Email address seems invalid."
                 },
                 email_confirmation:     {
                        required: "Email address is required.",
                        equalTo: "Email addresses do not match."
                 },
                 web_user_country:   {
                        required: "Please choose your country."
                 }
             },
             submitHandler:  function(form) {
                $.ajax({

您可以使用 jQuery 中提供的选项大大简化此验证：

$("#new_web_user").validate({
    errorContainer: '#error_mail',
    errorLabelContainer: '#actual_errors',
    wrapper:'li',
    //your rules and messages here
});

然后，将您的 HTML 更改为更像这样的内容：

<p id="error_mail" class="hide error">
  We&#39;re sorry, the fields highlighted in red are required 
  <ul id="actual_errors"></ul>
</p>

请注意，不要 adding/removing 您想要 #error_mail 上的错误 class，只需始终设置它，因为它只会在出现问题时可见。 .
