Formik 验证模式是的，什么时候是 "answer" 或 "another answer"

Question

基本上我想做的就是说如果 region = "Europe" 或 "other" 那么该字段是必需的，确实查看了 formik 文档但没有找到任何东西。

<Formik
enableReinitialize={true}
initialValues={{
    name: currentBankData.name || '',
    address: currentBankData.address || '',
    country: currentBankData.country || '',
    region: currentBankData.region || '',
    city: currentBankData.city || '',
    swiftCode: currentBankData.swiftCode || '',
    routeCode: currentBankData.routeCode || '',
}}
validationSchema={Yup.object().shape({
    name: Yup.string().min(3).required('Name is required.'),
    address: Yup.string().required('Address is required.'),
    country: Yup.string().required('Country is required.'),
    region: Yup.string().required('Region is required.'),
    city: Yup.string().required('City is required.'),

    swiftCode: Yup.string().when('region', {
        is: 'Europe' || 'other,      //Would like to do something like this but 
                                     doesnt work :)

        then: Yup.string()
            .required('SwiftCode is required.')
            .matches(
                /[A-Z]{6}[A-Z0-9]{2}([A-Z0-9]{3})?/i,
                'This is not the correct Swift Code'
            ),
    }),

    routeCode: Yup.string().when('region', {
        is: 'USA',
        then: Yup.string().required('RouteCode is required.'),
    }),

    verified: Yup.bool(),
})}

使用 mixe oneOf

试试这个

validationSchema={Yup.object().shape({
                    name: Yup.string().min(3).required('Name is required.'),
                    address: Yup.string().required('Address is required.'),
                    country: Yup.string().required('Country is required.'),
                    region: Yup.string().required('Region is required.'),
                    city: Yup.string().required('City is required.'),

                    swiftCode: Yup.string().when('region', {
                        is: oneOf(['Europe', 'Europe', 'other'] as const),
                                                 

                        then: Yup.string()
                            .required('SwiftCode is required.')
                            .matches(
                                /[A-Z]{6}[A-Z0-9]{2}([A-Z0-9]{3})?/i,
                                'This is not the correct Swift Code'
                            ),
                    }),

                    routeCode: Yup.string().when('region', {
                        is: 'USA',
                        then: Yup.string().required('RouteCode is required.'),
                    }),

                    verified: Yup.bool(),
                })}

    Finally Works
validationSchema={Yup.object().shape({
                    name: Yup.string().required('Name is required.'),
                    address: Yup.string().required('Address is required.'),
                    country: Yup.string().required('Country is required.'),
                    region: Yup.string().required('Region is required.'),
                    city: Yup.string().required('City is required.'),

                    swiftCode: Yup.string().when('region', (region, schema) => {
                        return ['Europe', 'other'].includes(region)
                            ? schema
                                    .required('SwiftCode is required.')
                                    .matches(
                                        /[A-Z]{6}[A-Z0-9]{2}([A-Z0-9]{3})?/i,
                                        'This is not the correct Swift Code'
                                    )
                            : schema.matches(
                                    /[A-Z]{6}[A-Z0-9]{2}([A-Z0-9]{3})?/i,
                                    'This is not the correct Swift Code'
                              );
                    }),

                    routeCode: Yup.string().when('region', {
                        is: 'USA',
                        then: Yup.string().required('RouteCode is required.'),
                    }),

                    verified: Yup.bool()
