React final form 至少一个必填字段

Question

我有以下内容：

export const isOneFieldValid = (val: string) => { 
  console.log(val)
  return val ? undefined : true
}

...
const validate = (field: string) => {
  switch (field) {
    case 'email': {
      return composeValidators(isOneFieldValid, isValidEmail, hasStringeMaxLength)
    }
    case 'workPhone':
    case 'homePhone':
    case 'mobile': {
      return composeValidators(isOneFieldValid, isNumber, hasNumberMaxLength)
    }
    default:
      return undefined
  }
}
...

这验证了所有 4 个字段，但是有没有一种方法可以只验证一个字段，假设它们都是空的？

只要有一种联系用户的方式，我就可以提交表单

听起来您需要表单级别的验证，而不是字段级别的验证？

<Form
    onSubmit={onSubmit}
    validate={values => {
            const errors = {}
            if (values.email && isValidEmail && hasStringMaxLength) {
              return ;
            } else {
             errors.email = 'Require';
            }
            if (writeFunctionToCheckWorkPhone) {
              return;
            } else {
              error.workPhone = 'Require';
            }
            if (writeFunctionToCheckHomePhone) {
              return ;
            } else {
              error.homePhone = 'Require';
            }
           if (writeFunctionToCheckMobile) {
              return ;
            } else {
              error.mobile = 'Require';
            }
            return errors;
          }}
    ...
