我们可以在下面提到的 formik YupValidationSchema 中添加自定义验证吗？

YupValidationSchema = () => {
        return Yup.object({
             Email: Yup.string()
            .max(256, "Length exceed 256 chars")
            .matches(EMAIL_REGEXP, "Enter a valid email address")
            .required("Email is required")
})
}

我需要为电子邮件字段添加一个验证，就像它应该接受某些域一样

let domainVal = companyName.some((val) => email.includes(val));
     if(!domainVal) error('Invalid')
     else  success('Valid');

谁能帮助我如何在 yupvalidationschema 中添加此域验证代码？

最佳答案

您可以使用 Yup test method为您的电子邮件添加自定义验证

基本语法:.test("test-name", "Error message", function)

return Yup.object({
             Email: Yup.string()
            .max(256, "Length exceed 256 chars")
            .matches(EMAIL_REGEXP, "Enter a valid email address")
            .required("Email is required")
            .test("email-include-domain", "Email Must include domain", (value) => companyNames.some((company) => value.includes(company));
