Just starting out with React, I'm working on a basic React application that showcases all the countries in the world on the screen along with a small search bar to display data for the searched country.

I'm facing an issue where I can't figure out how to display the selected country when clicked in the scrollbar.
Below is the code snippet from app.js:
import React, { Component } from 'react';
import './App.css';
import NavBar from '../Components/NavBar';
import SideBar from './SideBar';
import CountryList from '../Components/SideBarComponents/CountryList';
import Scroll from '../Components/SideBarComponents/Scroll';
import Main from './Main';
import SearchCountry from '../Components/MainComponents/SearchCountry';
import SearchedCountry from '../Components/MainComponents/SearchedCountry';
import Datas from '../Components/MainComponents/Datas';
class App extends Component {
constructor() {
super();
this.state = {
nations: [],
searchField: '',
button: false
}
}
onSearchChange = (event) => {
this.setState({searchField: event.target.value});
console.log(this.state.searchField)
}
onClickChange = () => {
this.setState(prevState => ({
button: true
}))
}
render() {
const {nations, searchField, button, searchMemory} = this.state;
const searchedNation = nations.filter(nation => {
if(button) {
return nation.name.toLowerCase().includes(searchField.toLowerCase())
}
});
return (
<div>
<div>
<NavBar/>
</div>
<Main>
<div className='backgr-img'>
<SearchCountry searchChange={this.onSearchChange} clickChange={this.onClickChange}/>
<SearchedCountry nations={searchedNation}/>
</div>
<Datas nations={searchedNation}/>
</Main>
<SideBar>
<Scroll className='scroll'>
<CountryList nations={nations} clickFunc/>
</Scroll>
</SideBar>
</div>
);
}
componentDidMount() {
fetch('https://restcountries.eu/rest/v2/all')
.then(response => response.json())
.then(x => this.setState({nations: x}));
}
componentDidUpdate() {
this.state.button = false;
}
}
export default App;
The countryList component:
import React from 'react';
import Images from './Images';
const CountryList = ({nations, clickFunc}) => {
return (
<div className='container' style={{display: 'grid', gridTemplateColumns: 'repeat(auto-fill, minmax(115px, 3fr)'}}>
{
nations.map((country, i) => {
return (
<Images
key={country.numericCode}
name={country.name}
flag={country.flag}
clickChange={clickFunc}
/>
);
})
}
</div>
)
}
export default CountryList;
And here's the images.js file:
import React from 'react';
import './images.css'
const Images = ({name, capital, region, population, flag, numericCode, clickChange}) => {
return (
<div className='hover bg-navy pa2 ma1 tc w10' onClick={clickChange = () => name}>
<img alt='flag' src={flag} />
<div>
<h6 className='ma0 white'>{name}</h6>
{capital}
{region}
{population}
{numericCode}
</div>
</div>
);
}
export default Images;
I was thinking of using the onClick event on the individual country to retrieve and display the name of the selected country. Then, I would update the searchField with the name and set the button state to true to trigger the searchedNation function. Thanks in advance to anyone who can help me with this!
