How to receive data in form from another component

大家好,我正在构建一个反应天气应用程序,允许用户输入他们的城市名称,并将天气信息显示给用户。

问题是,我在表单中有输入和按钮,并且我想从另一个名为 WeatherApp 的组件接收数据。

如何链接这两个组件

表单组件

import '../App.css';
import Input from './Input';
import Button from './Button';
import { useState } from 'react';

const Form = ({handleQueryChange}) => {
    const [city, setCity] = useState('')

    const handleChange = (e) => {
        setCity(e.target.value)

    }

    const handleSubmit  = (e) => {
        e.preventDefault();
        handleQueryChange(city);

    }

    return (  
    <div>
        <form className="inputForm" onSubmit={handleSubmit}>
       <Input value={city} onChange={handleChange} />
       <Button/>
        </form>

    </div>);
}

export default Form;



和天气应用组件

import React from 'react';
import { BrowserRouter,  Routes,Route } from 'react-router-dom';
import { useState, useEffect } from 'react';
import { WiDaySunny,WiCloud, WiNightCloudy,WiHumidity, WiNightClear } from 'react-icons/wi';
import Layout from './Layout';
import Home from './Home';
import Minutecast from './Minutecast';
import Hourly from './Hourly';
import Today from './Today';
import '../App.css';


const WeatherApp = () => {
const [data, setData] = useState([]);
const [query, setQuery] = useState('Accra');

const handleQueryChange = (data) => {
    setQuery(data.location.name);

}

const getWeatherIcons = (description) =>{
    switch(description.toLowerCase()) {
        case 'sunny':
            return <WiDaySunny size='100px'/>;
        case 'cloud':
                return <WiCloud  size='100px'/>;
        case 'clear':
                return <WiNightClear size='100px'/>;
        case 'partly cloudy':

                return <WiNightCloudy size='150px' color='blue' />;
        default:
                return <WiDaySunny color='red' size='100px' />;

    }
}

const convertToWhole = (tem) =>{
  const whole = Math.trunc(tem);
  return whole;


}

useEffect(()=>{

const fetchWeatherData = async () => {
  try {
    const response = await fetch(`https://api.weatherapi.com/v1/forecast.json?key=95f0ddb3a06a4a358cf223933242311&q=${query}&days=10&aqi=yes&alerts=no`);
    const result = await response.json();
    setData(result);

  console.log(result);
  } catch (error) {
    console.error("Error fetching weather data:", error);
  }

};
fetchWeatherData();
}, [data]);



    return ( <>
    <div className="formContainer">
    {/* <Form onSubmit={handleQueryChange} /> */}
    </div>
    <BrowserRouter>
    <Routes>
       <Route path ='/'  element={< Layout />}>
       <Route index element={<Home  data={data} getWeatherIcons={getWeatherIcons} convertToWhole={convertToWhole}/>} />
       <Route path='minutecast' element={<Minutecast />}/>
       <Route path='hourly' element={<Hourly data={data} convertToWhole={convertToWhole}/>}/>
       <Route path='today'element={<Today data={data} />}/>
     </Route>
     </Routes>
   </BrowserRouter>

    </>
    )

}

export default WeatherApp;
