Question

我从React开始，现在我面临着表单验证的挑战，为此，我寻找Formik和Yup库来寻找进行验证的方法但是事实证明，没有如何验证“输入类型='日期'”的示例，我仅看到示例使用“ DatePicker”的示例，请问是否有任何方法可以使用以下方法解决此问题： “输入类型='日期' 然后，我将向您展示如何尝试验证此日期。

    const validationSchema = Yup.object().shape({
      name: Yup.string()
      .min(2,"El nombre debe contener mas de 2 caracteres")
      .max(60,"El nombre no debe exceder de los 60 caracteres")
      .required("*El nombre es requerido"),
      inicio: Yup.date()
      .min(Yup.ref('originalEndDate'),
      ({ min }) => `Date needs to be before ${formatDate(min)}!!`,)
    });
    function formatDate(date) {
      return new Date(date).toLocaleDateString()
     }

 <Formik initialValues={{ name:"",inicio:""}} validationSchema={validationSchema}>
                {( {values,
                    errors,
                    touched,
                    handleChange,
                    handleBlur,
                    handleSubmit,
                    isSubmitting }) => (
                        <Form.Group>
                            <Form.Row>
                                <Form.Label column="sm" lg={1}>

我正在寻找解决方案，如果存在的话

使用变换：

import { date, object } from "yup";

const today = new Date();

const schema = object({
  birthday: date().transform(parseDateString).max(today),
});

const isValid = schema.validateSync({
  birthday: "2020-02-02",
});

参考：https://codedaily.io/tutorials/175/Yup-Date-Validation-with-Custom-Transform

是的：https://github.com/jquense/yup#mixedtransformcurrentvalue-any-originalvalue-any--any-schema
