Yup子模式访问父值(或将值传递给子模式)

import * as Yup from 'yup';

const usernameSchema = Yup.string()
  .required('Username is required')
  .min(3, 'Username must be at least 3 characters');

const emailSchema = Yup.string()
  .required('Email is required')
  .email('Invalid email address');

const passwordSchema = Yup.string()
  .required('Password is required')
  .min(6, 'Password must be at least 6 characters');

const userSchema = Yup.object().shape({
  username: usernameSchema,
  email: emailSchema,
  password: passwordSchema,
});

const nestedSchema = Yup.object().shape({
  parentField: Yup.string().required(),
  childField: Yup.string().required().test(
    'is-parent-field-valid',
    'Parent field must be valid',
    (childValue, context) => {
      const parentValue = context.parent.parentField;
      // 在这里进行验证逻辑
      return parentValue === 'valid';
    }
  ),
});

const nestedSchema = Yup.object().shape({

    }
  ),
});

try {

} catch (err) {
