反应挂钩形式动态输入控件不起作用

Question

我正在使用 React Hook 表单，我想根据一个单选按钮的选定条件动态设置一个文本输入框。我有跟踪送货方式的单选按钮，包括家庭、办公室和其他方式。如果用户单击其他，我想显示一个输入框并隐藏单选按钮。我希望这是有道理的。我试了很多方法都不行。任何想法都会对我无法正常工作有所帮助

 {(watch('tag') == 'others') ?   <Input
                  {...register('otherField')}
                  label="Others"
                  variant="outline"
                  className="col-span-2 w-full"
                />: 
                <div className="flex items-center space-x-4 rtl:space-x-reverse">
                <Radio
                  id="home"
                  {...register('tag')}
                  type="radio"
                  value={'home'}
                  label="Home"
                  name={'tag'}
                />
                <Radio
                  id="work"
                  
                  {...register('tag')}
                  type="radio"
                  value={'Work'}
                  label="Work"
                  name={'tag'}
                />
                <Radio
                  id="others"
                  {...register('tag')}
                  type="radio"
                  value={'others'}
                  label="Others"
                  name={'tag'}
                />
              </div> 
              }

单选按钮组件

import React, { InputHTMLAttributes } from 'react';
import styles from './radio.module.css';

export interface Props extends InputHTMLAttributes<HTMLInputElement> {
  className?: string;
  label?: string;
  name: string;
  id: string;
  error?: string;
}

const Radio = React.forwardRef<HTMLInputElement, Props>(
  ({ className, label, name, id, error, ...rest }, ref) => {
    return (
      <div className={className}>
        <div className="flex items-center">
          <input
            id={id}
            name={name}
            type="radio"
            ref={ref}
            className={styles.radio_input}
            {...rest}
          />

          <label htmlFor={id} className="text-body text-sm">
            {label}
          </label>
        </div>

        {error && (
          <p className="my-2 text-xs ltr:text-right rtl:text-left text-red-500">
            {error}
          </p>
        )}
      </div>
    );
  }
);
export default Radio;

你好，我刚刚将你的代码复制到这个沙盒中，它运行良好：codesandbox

App.js

import "./styles.css";
import { useForm } from "react-hook-form";

import Radio from "./Radio";

export default function App() {
  const { register, handleSubmit, watch } = useForm();
  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      {watch("tag") === "others" ? (
        <input
          {...register("otherField")}
          variant="outline"
          className="col-span-2 w-full"
        />
      ) : (
        <div className="flex items-center space-x-4 rtl:space-x-reverse">
          <form>
            <Radio
              id="home"
              {...register("tag")}
              type="radio"
              value={"home"}
              label="Home"
              name={"tag"}
            />
            <Radio
              id="work"
              {...register("tag")}
              type="radio"
              value={"Work"}
              label="Work"
              name={"tag"}
            />
            <Radio
              id="others"
              {...register("tag")}
              type="radio"
              value={"others"}
              label="Others"
              name={"tag"}
            />
            <button onClick={handleSubmit((val) => console.log(val))}>
              click
            </button>
          </form>
        </div>
      )}
    </div>
  );
}
