将数据传递给 React 中的另一个组件

Question

In my code I have it so the user can search for the type of Pokémon they want and when the user submits it, I want to send it to another component to display all the information. The issue is the data isn't passing through to the other component I'm pretty new to react so I might be missing something obvious. This is the component that retrieves the data from the api.

const Search = () => {
  const [inputValue, setInputValue] = useState("");
  const [userData, setUserData] = useState([]);
  const userInput = (e) => {
    setInputValue(e.target.value);
  };
  const handleClick = (e) => {
    e.preventDefault();
    apiCall(inputValue);
  };

  const apiCall = async (name) => {
    const url = `https://pokeapi.co/api/v2/pokemon/${name}`;
    const response = await fetch(url);
    const data = await response.json();
    setUserData(data);
  };
  return (
    <div>
      <button className="btn" onClick={handleClick}>
        Search
      </button>
      <input
        type="search"
        onChange={userInput}
        value={inputValue}
        placeholder="Enter your pokemon name"
        className="btn-search"
      ></input>
      <div>
        <PokiApi props={userData} />
      </div>
    </div>
  );
};

This is the component that I want to display the api data to the page.

export default class PokiApi extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: props.props,
    };
  }
  render() {
    return (
      <div>
        <div>
          <div>{this.state.data}</div>
        </div>
      </div>
    );
  }
}

When I run it this is what I get

Answer 1

Try this:

const PokiApi({props}) {
  return (
    <div>
      <div>
        <div>{props}</div>
      </div>
    </div>
  );
}

the props in the function component will be userData and props.props is undefined

This is what you need

const Search = () => {
  const [inputValue, setInputValue] = useState('');
  const [userData, setUserData] = useState();

  const userInput = (e) => {
    setInputValue(e.target.value);
  };

  const apiCall = async (name) => {
    const url = `https://pokeapi.co/api/v2/pokemon/${name}`;
    const response = await fetch(url);
    const data = await response.json();
    setUserData(data);
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    apiCall(inputValue);
  };

  return (
    <div>
      <form action='' onSubmit={handleSubmit}>
        <button className='btn'>Search</button>
        <input type='search' onChange={userInput} value={inputValue} placeholder='Enter your pokemon name' className='btn-search' />
      </form>
      <div>
        <PokiApi data={userData} />
      </div>
    </div>
  );
};

const PokiApi = ({ data }) => {
  // data is an array
  if (!data) {
    return <div>Enter pokemon to get the data</div>;
  }
  return (
    <div>
      <h1>{data.name}</h1>
    </div>
  );
};
