jQuery中的2个(多个)电子邮件验证文本输入

现在我有(适用于一封电子邮件)：

<script language="JavaScript">
$(document).ready(function(){
    $("form#editclient").validate({
            rules: {
            Contact: {
                required: true
            },Clientname: {
                required: true
            },ClientLogin: {
                required: true
            },ClientPassword: {
                required: true
            },email: {
                required: true,multiemail: true
            }
        },messages: {
            Contact: {
                required: "Please enter your Contact Nmae."
            },Clientname: {
                required: "Please enter your Client Name"
            },ClientLogin: {
                required: "Please enter a login."
            },ClientPassword: {
                required: "Please enter a password"
            },email: {
                required: "Please enter an Email Address",multiemail: "You must enter a valid email,or comma separate multiple"
            }
        }
});
});
</script>
    <input type="Text" id="email" name="Email" value="#Trim(Email)#" maxlength="60" class="inputText430 email required">

我发现这应该让多个验证器工作：

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

但我不能让它正常工作.有人可以帮助我在一个文本字段中验证2个或更多电子邮件吗？

提前致谢.

<form>
    <input id='emailTest' name='emailTest' />
    <input type='submit' />
</form>
    <script type="text/javascript">
    jQuery.validator.addMethod(
    "multiemail",element) {
        var email = value.split(/[;,and ;
        valid = true;
        for (var i in email) {
            value = email[i];
            valid = valid && jQuery.validator.methods.email.call(this,element);
        }
        return valid;
    },jQuery.validator.messages.multiemail
);

$("form").validate({
    debug: true,rules: {
            emailTest: {
                multiemail: true
            }
        },messages: {
            emailTest: {
                multiemail: "You must enter a valid email,or comma separate multiple"
            }
        },submitHandler: function(form) {
            return false;
        }
});
