Question:
How to update the react component after clicking on the search button?

To update the react component after clicking on the search button the e.target should be called with the argument being the name or id of the form element you want to target, not the string "query". 


Additionally, you should use e.target.value to get the value of the input field. Here's the code:


import { useState } from "react";

import CountrySWR from "./CountrySWR";



export default function SearchForm(){

    const [countryName, setCountryName] = useState("a");


 const handleSubmit = (e:any) => {

    e.preventDefault();

    // in here query is a id of input which located in form

      console.log(e.target.query.value)

}


    return (

        <>

<form onSubmit={handleSubmit}>

  <input id='query' type="text" />

  <button type='submit'>submit</button>

</form>

            <CountrySWR name={countryName}/>

        </>

    );

};
