jQuery 验证插件多个电子邮件地址

Question

我有以下 jQuery 验证插件:

<script type="text/javascript" src="/requires/js/jquery.min.js"></script>
<script type="text/javascript" src="/requires/js/jquery.validate.js"></script>
<script type="text/javascript"> 
    $(document).ready(function() {
        $("#form").validate({
            rules: {
                name: {
                    required: true,
                    minlength: 2
                },
                email: {
                    required: true,
                    email: true
                },
                emails: {
                    required: true,
                    email: true
                }
            },
            messages: {
                name: {
                    required: "Je bent vergeten om je naam in te vullen.",
                    minlength: "Je bent vergeten om je naam in te vullen."
                },
                email: {
                    required: "Je bent vergeten om je emailadres in te vullen.",
                    email: "Het opgegeven emailadres is niet geldig."
                },
                emails: {
                    required: "Je bent vergeten om het emailadres van je vriend(in) in te vullen.",
                    email: "Je moet een geldig e-mailadres van je vriend(in) invullen."
                }
            }
        });
    }); 
</script>

<form id="form" method="post">
Jouw naam: <input type="text" name="name"><br />
Jouw e-mailadres: <input type="text" name="email"><br />
Het e-mailadres van je vriend(in): <input type="text" name="emails"><br />
<input type="submit" value="Verstuur">
</form>

按值电子邮件，人们必须可以提供多个电子邮件地址，例如 test@test.com;test2@test.com 或 test@test.com,test@test2.com

当您执行此操作时，验证插件会给出错误:Je moet een geldig e-mailadres van je vriend(in) invullen。

如何解决这个问题？

Answer 1

这是在 addMethod 的帮助下添加的自定义函数:

jQuery.validator.addMethod(
    "multiemail",
     function(value, element) {
         if (this.optional(element)) // return true on optional element 
             return true;
         var emails = value.split(/[;,]+/); // split element by , and ;
         valid = true;
         for (var i in emails) {
             value = emails[i];
             valid = valid &&
                     jQuery.validator.methods.email.call(this, $.trim(value), element);
         }
         return valid;
     },

    jQuery.validator.messages.email
);
