使用 react-hook-form 进行 react-phone-number-input 验证

Question

phone-number-input](https://gitlab.com/catamphetamine/react-phone-number-input#readme) with react-hook-form 它正常工作。我想用来自 react-phone-number- 的 isValidPhoneNumber 验证 phone 号码输入，但我不知道如何使用 react-hook-form 实现。我在这里阅读了一些关于这个问题的帖子，但没有正确的答案。这是我的代码：

import { useForm, Controller } from 'react-hook-form'
import PhoneInput, { isValidPhoneNumber } from 'react-phone-number-input'

import 'react-phone-number-input/style.css'

const MyForm = () => {
  const {
    handleSubmit,
    formState: { errors },
    control,
  } = useForm()

  const onSubmit = (data) => {
    console.log(data)
  }

  return (
    <form onSubmit={handleSubmit(onSubmit)} className="user-info-form">
      <div>
        <label htmlFor="phone-input">Phone Number</label>
        <Controller
          name="phone-input"
          control={control}
          rules={{ required: true }}
          render={({ field: { onChange, value } }) => (
            <PhoneInput
              value={value}
              onChange={onChange}
              defaultCountry="TH"
              id="phone-input"
            />
          )}
        />
        {errors.phone && <p className="error-message">Invalid Phone</p>}
      </div>
    </form>
  )
}

export default MyForm

您可以通过为控制器 rules 道具的 validate 键传递 isValidPhoneNumber 方法来实现此目的。

而且你也打错了。在你的 Controller 名字中是 phone-input。因此，您必须检查 errors 对象中的 phone-input 键而不是 phone.

请找出答案。

import React from "react";
import { useForm, Controller } from "react-hook-form";
import PhoneInput, { isValidPhoneNumber } from "react-phone-number-input";

import "react-phone-number-input/style.css";

const MyForm = () => {
  const {
    handleSubmit,
    formState: { errors },
    control
  } = useForm();


  const onSubmit = (data) => {
    console.log(data);
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)} className="user-info-form">
      <div>
        <label htmlFor="phone-input">Phone Number</label>
        <Controller
          name="phone-input"
          control={control}
          rules={{
            validate: (value) => isValidPhoneNumber(value)
          }}
          render={({ field: { onChange, value } }) => (
            <PhoneInput
              value={value}
              onChange={onChange}
              defaultCountry="TH"
              id="phone-input"
            />
          )}
        />
        {errors["phone-input"] && (
          <p className="error-message">Invalid Phone</p>
        )}
      </div>
    </form>
  );
};

export default MyForm;
