你试过这个吗?

$("Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$", messages: { regex: "The text is invalid..." } })

注意:请确保在正则表达式前面添加另一个“\”来转义所有的“\”，否则正则表达式将无法正常工作。

我让它像这样工作:

$.validator.addMethod(
    "regex",
    function(value, element, regexp) {
        return this.optional(element) || regexp.test(value);
    },
    "Please check your input."
);


$(function () {
    $('#uiEmailAdress').focus();
    $('#NewsletterForm').validate({
        rules: {
            uiEmailAdress:{
                required: true,
                email: true,
                minlength: 5
            },
            uiConfirmEmailAdress:{
                required: true,
                email: true,
                equalTo: '#uiEmailAdress'
            },
            DDLanguage:{
                required: true
            },
            Testveld:{
                required: true,
                regex: /^[0-9]{3}$/
            }
        },
        messages: {
            uiEmailAdress:{
                required: 'Verplicht veld',
                email: 'Ongeldig emailadres',
                minlength: 'Minimum 5 charaters vereist'
            },
            uiConfirmEmailAdress:{
                required: 'Verplicht veld',
                email: 'Ongeldig emailadres',
                equalTo: 'Veld is niet gelijk aan E-mailadres'
            },
            DDLanguage:{
                required: 'Verplicht veld'
            },
            Testveld:{
                required: 'Verplicht veld',
                regex: '_REGEX'
            }
        }
    });
});

确保正则表达式在/:-)之间

你可以使用addMethod()

e.g

$.validator.addMethod('postalCode', function (value) { 
    return /^((\d{5}-\d{4})|(\d{5})|([A-Z]\d[A-Z]\s\d[A-Z]\d))$/.test(value); 
}, 'Please enter a valid US or Canadian postal code.');

这里有好文章https://web.archive.org/web/20130609222116/http://www.randallmorey.com/blog/2008/mar/16/extending-jquery-form-validation-plugin/

你可以使用extra -methods.js文件中定义的模式。注意这个additional-methods.js文件必须包含在jQuery验证依赖之后，然后你就可以使用它了

$("#frm").validate({ rules: { Textbox: { pattern: /^[a-zA-Z'.\s]{1,40}$/ }, }, messages: { Textbox: { pattern: 'The Textbox string format is invalid' } } }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/additional-methods.min.js"></script> <form id="frm" method="get" action=""> <fieldset> <p> <label for="fullname">Textbox</label> <input id="Textbox" name="Textbox" type="text"> </p> </fieldset> </form>

没有理由将正则表达式定义为字符串。

$.validator.addMethod(
    "regex",
    function(value, element, regexp) {
        var check = false;
        return this.optional(element) || regexp.test(value);
    },
    "Please check your input."
);

and

telephone: { required: true, regex : /^[\d\s]+$/, minlength: 5 },

这样更好，不是吗?

这对我来说是有效的，作为验证规则之一:

    Zip: {
                required: true,
                regex: /^\d{5}(?:[-\s]\d{4})?$/
            }

希望能有所帮助
