用react钩子形式进行电话号码输入验证

Question

电话号码输入](https://gitlab.com/catamphetamine/react-phone-number-input#readme)与反应钩式，并正常工作.我想验证电话号码与isValidPhoneNumber从反应电话号码输入，但我不知道如何实现与反应挂钩形式。我在这里读过一些关于这个问题的帖子，但我没有正确的答案。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的isValidPhoneNumber支柱的validate键传递rules方法来实现这一点。

你也做了个错字。在您的Controller名称中是phone-input。因此，您必须检查errors对象中的errors键，而不是phone。

请找到答案。

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;
