Question

我正在使用jQuery Validation plugin验证我的表单。

我想按照美国ZIPCode格式验证邮政编码： -

> 12345
> 12345-6789
> 12345 6789

根据我的代码，验证邮政编码应该是最大5和所有数字。

请参阅以下代码：

    <script src="~/Scripts/js/jquery.validate.js"></script>

<script>

    $().ready(function () {

        // validate signup form on keyup and submit
        $("#locationSetup").validate({
            rules: {
                'Address.AddressStreet': "required",
                'Address.City': "required",
                'Address.State.Country.CountryIsoCode': "required",
                'Address.State.SubnationalIsoCode': "required",
                'Address.PostalCode': {
                    required: true,
                    minlength: 5,
                    maxlength: 5,
                    digits: true
                }
            },
            messages: {
                'Address.AddressStreet': "Please enter your Street Address!",
                'Address.City': "Please select your City!",
                'Address.State.Country.CountryIsoCode': "Please  select your Country!",
                'Address.State.SubnationalIsoCode': "Please  select your State!",
                'Address.PostalCode': {
                    required: "Please enter your Postal Code!",
                    minlength: "Your Postal Code must be 5 numbers!",
                    maxlength: "Your Postal Code must be 5 numbers!",
                    digits: "Your Postal Code must be 5 numbers!"
                }
            }
        });

    });
</script>

@using (Html.BeginForm(Model.Step.ToString(), "Provision", FormMethod.Post, new Dictionary<string, object> { { "id", "locationSetup" } }))

<table width="100%" id="locInfo">
            <colgroup>
                <col width="30%" />
                <col />
            </colgroup>
            <tr>
                <th><label>@AddressResource.COUNTRY_LABEL_TEXT:</label> <span class="redtext">(Required)</span></th>
                <td>
                   @* @Html.HiddenFor(m => m.Address.State.Country.CountryIsoCode)*@
                   @Html.DropDownListFor(m => m.Address.State.Country.CountryIsoCode, ProvisioningHubProxy.GetCountriesList(),
                                htmlAttributes: new { @id = "Countries", @name = "Countries" })
                </td>
            </tr>
            <tr>
                <th> <label>@AddressResource.STATES_LABEL_TEXT:</label><span class="redtext">(Required)</span></th>
                <td> @Html.DropDownListFor(m => m.Address.State.SubnationalIsoCode, ProvisioningHubProxy.GetStatesList(),
                                htmlAttributes: new { @id = "States", @name = "States" })</td>
            </tr>
            <tr>
                <th><label>@AddressResource.CITY_LABEL_LABEL_TEXT:</label><span class="redtext">(Required)</span></th>
                <td> @Html.TextBoxFor(m => m.Address.City, htmlAttributes: new { @name = "City", @id = "City" })</td>
            </tr>
            <tr>
                <th> <label>@AddressResource.STREET_NAME_LABEL_TEXT:</label><span class="redtext">(Required)</span></th>
                <td>@Html.TextBoxFor(m => m.Address.AddressStreet, htmlAttributes: new { @name = "StreetName", @id = "StreetName" })</td>
            </tr>
            <tr>
                <th><label>@AddressResource.US_POSTAL_CODE_LABEL_TEXT:</label><span class="redtext">(Required)</span></th>
                <td>@Html.TextBoxFor(m => m.Address.PostalCode, htmlAttributes: new { @name = "ZipCode", @id = "ZipCode", @required = "required" })</td>
            </tr>
        </table>

}

请建议。

Answer 1

添加自定义验证器：

jQuery.validator.addMethod("zipcode", function(value, element) {
  return this.optional(element) || /^\d{5}(?:-\d{4})?$/.test(value);
}, "Please provide a valid zipcode.");

_如果您想在邮政编码之间接受空格¹，请使用/^\d{5}(?:[\s-]\d{4})?$/作为模式。

然后在您的选项中指定它：

rules: {
  ...
  'Address.PostalCode': {
    ...
    zipcode: true,
    ...
  },
  ...
}

请注意，扩展程序库additional-methods.js也有一个zipcodeUS验证程序（但除非你使用其他任何一个，否则包含它可能没有意义。）

¹根据规范，正确格式化的邮政编码由五（5）个数字或五（5）个数字跟随符号连字符（ - ）和四（4）个附加数字组成。一个空间不应该技术上可以接受，但无论如何我都会提供模式。

Answer 2

只需添加the additional-methods.js file并使用zipcodeUS规则。

$("#locationSetup").validate({
    rules: {
        // rules,
        'Address.PostalCode': {
            required: true,
            zipcodeUS: true // <-- use it like this
        }
    },
....

如果您不想包含additional-methods.js文件，可以将以下方法复制到代码中...

jQuery.validator.addMethod("zipcodeUS", function(value, element) {
    return this.optional(element) || /\d{5}-\d{4}$|^\d{5}$/.test(value)
}, "The specified US ZIP Code is invalid");

Answer 3

您可以定义自定义验证器：

jQuery.validator.addMethod('zipcode', function(value, element) {
  return this.optional(element) || !!value.trim().match(/^\d{5}(?:[-\s]\d{4})?$/);
}, 'Invalid zip code');

然后像这样使用它

<input class="zipcode"/>

Answer 4

在附加方法.js中提供了邮政编码验证程序，但如果您要使除美国以外的任何国家/地区的表单无效，我会质疑为什么要求提供国家/地区信息？请记住，世界上只有约5％的人口使用美国邮政编码。我建议您根据用户实际选择的国家/地区制作邮政编码验证程序。
