将规则添加到rules.js Magento2

如何将新规则添加到rules.js？我创建了extra-rules.js

define(
[
    'jquery',
    'Magento_Ui/js/lib/validation/validator'
], function ($, validator) {
    "use strict";
    return validator.addRule('phoneNO',
        function (value) {
            return value.length > 9 && value.match(/^(\(?(0|\+44)[1-9]{1}\d{1,4}?\)?\s?\d{3,4}\s?\d{3,4})$/);
        },
        $.mage.__('Please specify a valid phone number')
    );
});

如何将此规则合并到rules.js？

这是一个完整而实际的工作示例，用于向结帐输入字段添加自定义规则以检查最小年龄：

在模块中创建一个requirejs-config.js，以向validator对象添加Namespace/Modulename/view/frontend/requirejs-config.js以下内容的混合：

var config = {
    config: {
        mixins: {
            'Magento_Ui/js/lib/validation/validator': {
                'Namespace_Modulename/js/validator-mixin': true
            }
        }
    }
};

在Namespace/Modulename/view/frontend/web/js/validator-mixin.js包含以下内容的模块文件夹中创建一个js脚本：

define([
    'jquery',
    'moment'
], function ($, moment) {
    'use strict';

    return function (validator) {

        validator.addRule(
            'validate-minimum-age',
            function (value, params, additionalParams) {
                return $.mage.isEmptyNoTrim(value) || moment(value, additionalParams.dateFormat).isBefore(moment().subtract(params.minimum_age, 'y'));
            },
            $.mage.__("Sorry, you don't have the age to purchase the current articles.")
        );

        return validator;
    };
});

用法

如果要使用Magento PHP插件将输入字段插入到结帐收货地址，并使用之前添加的自定义规则来验证此字段的内容，请参见以下示例代码：

使用以下内容在模块di.xml的etc/frontend文件夹中创建一个文件：

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">    
    <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="CheckoutLayoutProcessor" type="Namespace\Modulename\Plugin\Block\Checkout\LayoutProcessor" />
    </type>
</config>

然后使用以下内容创建LayoutProcessor.php文件app/code/Namespace/Modulename/Plugin/Block/Checkout/LayoutProcessor.php，请根据需要进行更新：

编辑

感谢@ alan-storm在这里的解释https://alanstorm.com/the-curious-case-of-magento-2-mixins/和@ jisse-reitsma带来了方向

加上Magento 2文档http://devdocs.magento.com/guides/v2.2/javascript-dev-guide/javascript/js_mixins.html

原始rules.js返回包含所有规则的对象文字。您可以通过向该文件添加混合来修改该对象文字。Magento文档为如何执行此操作提供了一些指导：Magento Javascript Mixins

此处回答了相同的问题：Magento 2添加自定义验证规则

了解此系统的真正好方法是：https： //alanstorm.com/the-curious-case-of-magento-2-mixins/

并非完全是您要尝试做的事情，而是一个很好的参考资料：https : //www.youtube.com/watch?v=0fguDL5iEd0&t=540s

它为我工作：

在模块中创建一个requirejs-config.js，以向验证器对象添加混合到app / design / frontend / Vendor / Theme / Magento_Ui / requirejs-config.js，其内容如下：

var config = {
    config: {
        mixins: {
            'Magento_Ui/js/lib/validation/rules': {
                'Magento_Ui/js/lib/validation/rules-mixin': true
            }
        }
    }
};

在您的模块文件夹中的app / design / frontend / Vendor / Theme / Magento_Ui / web / js / lib / validation / rules-mixin.js中创建一个js脚本，其内容如下：

define([
    'jquery',
    'underscore',
    'moment',
    'mage/translate'
], function ($, _, moment) {
    'use strict';

    return function (validator) {
        var validators = {
            'letters-spaces-only': [
                function (value) {
                    return /^[a-zA-Z ]*$/i.test(value);
                },
                $.mage.__('Only letters and spaces.')
            ]
        };

        validators = _.mapObject(validators, function (data) {
            return {
                handler: data[0],
                message: data[1]
            };
        });

        return $.extend(validator, validators);
    };
});
