问题描述
我正在做一个ReactJS项目。我正在学习使用Yup
与FormIk
进行验证。以下代码运行正常:
const ValidationSchema = Yup.object().shape({
paymentCardName: Yup.string().required(s.validation.paymentCardName.required),
paymentCardNumber: Yup.string()
/*
.test(
"test-num",
"Requires 16 digits",
(value) => !isEmpty(value) && value.replace(/s/g, "").length === 16
)
*/
.test(
"test-ctype",
"We do not accept this card type",
(value) => getCardType(value).length > 0
)
.required(),
但在我取消test-num
注释的那一刻,开发工具就抱怨一个未实现的承诺:
如何让YUP根据我检测到的验证失败给我不同的错误字符串?
推荐答案
您可以使用addMethod方法创建两个这样的自定义验证方法。
Yup.addMethod(Yup.string, "creditCardType", function (errorMessage) {
return this.test(`test-card-type`, errorMessage, function (value) {
const { path, createError } = this;
return (
getCardType(value).length > 0 ||
createError({ path, message: errorMessage })
);
});
});
Yup.addMethod(Yup.string, "creditCardLength", function (errorMessage) {
return this.test(`test-card-length`, errorMessage, function (value) {
const { path, createError } = this;
return (
(value && value.length === 16) ||
createError({ path, message: errorMessage })
);
});
});
const validationSchema = Yup.object().shape({
creditCard: Yup.string()
.creditCardType("We do not accept this card type")
.creditCardLength('Too short')
.required("Required"),
});
