How do I close the modal window in react when clicking on the Add product button?

everyone. I can't write the code to close the modal window in React. I don't know how this can be done, I need that when clicking on the "Add" button, a modal window opens, the user enters the data, and clicking on the "Add product" button, the window closes immediately
Code:
import React from 'react';
import CatalogProducts from "./CatalogProducts";
import Info from "./Info";
import CreateProduct from "./CreateProduct";
import {Button} from 'react-bootstrap';
import Popup from 'reactjs-popup';
import 'reactjs-popup/dist/index.css';
import '../css/popup.css'
const Main = () => {
return (
<div>
<div className="d-flex justify-content-between" style={{ width: '33rem', margin: '10px' }}>
<Popup contentStyle={{width: "unset", backgroundColor: "red", border: "none", background: "none"}}
trigger={<Button> Add </Button>} modal>
<CreateProduct/>
</Popup>
<input placeholder={'search'}/>
<span>sort by</span>
<input/>
</div>
<CatalogProducts></CatalogProducts>
<Info></Info>
</div>
);
};
export default Main;
import React from 'react';
import {useDispatch} from "react-redux";
import {addProductAction} from "../action/productsAction";
import {ConfigProduct} from "../Utils/configProduct";
import '../css/popup.css'
import '../css/flex.css'
import {Button} from "react-bootstrap";
const CreateProduct = () => {
const dispatch = useDispatch()
const newProduct = new ConfigProduct()
function addProd() {
dispatch(addProductAction(newProduct))
}
return (
<div className = "popup">
<h2 style={{textAlign: "center", color: "red"}}>New product</h2>
<input className="item" placeholder="id" onChange={e => newProduct.idProd = e.target.value}/>
<input className="item" placeholder="info" onChange={e => newProduct.name = e.target.value}/>
<input className="item" placeholder="price" onChange={e => newProduct.infoProd = e.target.value}/>
<input className="item" placeholder="date" onChange={e => newProduct.price = e.target.value}/>
<input className="item" placeholder="enter url" onChange={e => newProduct.date = e.target.value}/>
<p>
<Button onClick={addProd}>Add product</Button>
</p>
</div>
);
};
export default CreateProduct;
I tried setting a flag to change the component class. but it didn't work out for me

In your main.js
[open, setOpen] = useState(false)
const closeModal = () => setOpen(false)
return (
<div>
<div className="d-flex justify-content-between" style={{ width: '33rem', margin: '10px' }}>
<Popup
contentStyle={
{width: "unset", backgroundColor: "red", border: "none", background: "none"}
}
trigger={<Button> Add </Button>}
modal
>
<CreateProduct closeModal={closeModal}/>
</Popup>
<input placeholder={'search'}/>
<span>sort by</span>
<input/>
</div>
<CatalogProducts></CatalogProducts>
<Info></Info>
</div>
)
and inside your CreateProduct.js
const CreateProduct = ({ closeModal }) => {
// your code
function addProd() {
dispatch(addProductAction(newProduct))
closeModal()
}
// rest of your code
)

how to connect two component when i click on submit button

I have some user components on which I used the navigation component and I am routing two components on it. when I click on the Device.js component button it should remove device.js and it should redirect to the Keyregister.js component which is having navigation component in it .It should change the value according to the props sent to it. But it is not happening.
user.js
import React from "react";

I cannot see anywhere in your naviagation component props you are passing device details.

link2name={"Key Upload"}
link3name={"KEY DOWNLOAD"} //should have device details in props

Why does a useCallback option have to be called with a class component in Reactjs?

I am stumped. I have been trying to get a simple cleartext button to work. I have tried all the option available on this platform but nothing is working for me. React Hook useCallback cannot be called in a class component. React Hooks must be called in a React function component or a custom React Hook. I have no idea why this error is occurring. I am pretty new to react can anyone please help? I am trying to clear the text on a click of the clear button.
import React, { Component, useCallback, useState } from "react";
import {
Button,
Input,
Footer,
Card,
CardBody,
CardImage,
CardTitle,
CardText
} from "mdbreact";
import blankImg from "./blank.gif";
import "./style.css";
import "./flags.min.css";
import countriesList from "./countries.json";
class App extends Component {
state = {
search: ""
};
renderCountry = country => {
const { search } = this.state;
var code = country.code.toLowerCase();
const handleClick = useCallback(() => {
e.target.value = '';
}, []);
return (
<div className="col-md-3" style={{ marginTop: "20px" }}>
<Card>
<CardBody>
<p className="">
<img
src={blankImg}
className={"flag flag-" + code}
alt={country.name}
/>
</p>
<CardTitle title={country.name}>
{country.name.substring(0, 15)}
{country.name.length > 15 && "..."}
</CardTitle>
</CardBody>
</Card>
</div>
);
};
onchange = e => {
this.setState({ search: e.target.value });
};
render() {
const { search } = this.state;
const filteredCountries = countriesList.filter(country => {
return country.name.toLowerCase().indexOf(search.toLowerCase()) !== -1;
});
return (
<div className="flyout">
<main style={{ marginTop: "4rem" }}>
<div className="container">
<div className="row">
<div className="col">
<Input

icon="search"
onChange={this.onchange}
/>
<button onClick={handleClick}> Click to clear</button>
</div>
<div className="col" />
</div>
<div className="row">

It is because you try to use hooks in a class based component. You can only use hooks like useCallback in functional components. Therefore you are mixing the concepts of object oriented and functional programming.
The following should do the trick:
import React, { Component, useCallback, useState } from "react";
import {
Button,
Input,
Footer,
Card,
CardBody,
CardImage,
CardTitle,
CardText
} from "mdbreact";
import blankImg from "./blank.gif";
import "./style.css";
import "./flags.min.css";
import countriesList from "./countries.json";
class App extends Component {
state = {
search: ""
};
const handleClick = (e) => {
e.target.value = '';
};
renderCountry = country => {
const { search } = this.state;
var code = country.code.toLowerCase();
return (
<div className="col-md-3" style={{ marginTop: "20px" }}>
<Card>
<CardBody>
<p className="">
<img
src={blankImg}
className={"flag flag-" + code}
alt={country.name}
/>
</p>
<CardTitle title={country.name}>
{country.name.substring(0, 15)}
{country.name.length > 15 && "..."}
</CardTitle>
</CardBody>
</Card>
</div>
);
};
onchange = e => {
this.setState({ search: e.target.value });
};
render() {
const { search } = this.state;
const filteredCountries = countriesList.filter(country => {
return country.name.toLowerCase().indexOf(search.toLowerCase()) !== -1;
});
return (
<div className="flyout">
<main style={{ marginTop: "4rem" }}>
<div className="container">
<div className="row">
<div className="col">
<Input
label="Search Country"
icon="search"
onChange={this.onchange}
/>
<button onClick={this.handleClick}> Click to clear</button>
</div>
<div className="col" />
</div>
<div className="row">
{filteredCountries.map(country => {
return this.renderCountry(country);
})}
</div>
</div>
</main>
<Footer color="indigo">
<p className="footer-copyright mb-0">
© {new Date().getFullYear()} Copyright
</p>
</Footer>
</div>
);
}
}
export default App;

useCallback hooks can only be used in functional components OR in a custom Hook NOT in class components.
You have declared your App component in class based approach i.e. Object oriented approach. To use useCallback hook for this, you should change your App component declaration to a functional component or Custom hook.
Something like this
function App() {
return (
<>Hello World!</>
);
}

you cannot useCallBack hook in class Component,we can do a simple thing to clear the button text, by using
a button text state, i.e. { btnTxt: "Clear ButtonText"} than update the state onclick
import React, { Component, useCallback, useState } from "react";
import {
Button,
Input,
Footer,
Card,
CardBody,
CardImage,
CardTitle,
CardText
} from "mdbreact";
import blankImg from "./blank.gif";
import "./style.css";
import "./flags.min.css";
import countriesList from "./countries.json";
class App extends Component {
state = {
search: "",
btnTxt: "Clear ButtonText"
};
renderCountry = country => {
const { search } = this.state;
var code = country.code.toLowerCase();
return (
<div className="col-md-3" style={{ marginTop: "20px" }}>
<Card>
<CardBody>
<p className="">
<img
src={blankImg}
className={"flag flag-" + code}
alt={country.name}
/>
</p>
<CardTitle title={country.name}>
{country.name.substring(0, 15)}
{country.name.length > 15 && "..."}
</CardTitle>
</CardBody>
</Card>
</div>
);
};
onchange = e => {
this.setState({ search: e.target.value });
};
render() {
const { search } = this.state;
const filteredCountries = countriesList.filter(country => {
return country.name.toLowerCase().indexOf(search.toLowerCase()) !== -1;
});

React Hooks trying to useState in array ref

I'm trying to work with Hooks in react but i have a doubt about useState and References. My problem is because i want to create multiple references in my jsx but i dont know how use the usestate like a Array, well in the insert of the usestate data.
import React, { useState, useEffect } from "react";
import { Row, Col, Image, ListGroup, Container } from "react-bootstrap";
import AOS from "aos";
import "./css/App.css";
import "aos/dist/aos.css";
import Skills from "./Components/Skills";
import Work from "./Components/Work";
const App = () => {
const [ref, setRef] = useState([]);
useEffect(() => {
AOS.init({
duration: 2000
});
});
function handleOnClick(event) {
ref.scrollIntoView();
}
return (
<div className="App">
<Row>
<Col className="menu text-center" lg={4}>
<div className="picture">
<Image
src={process.env.PUBLIC_URL + "/Images/picture.jpg"}
roundedCircle
/>
</div>
<h1 className="menu-name">Fulanito Detal</h1>
<h4 className="menu-office">Software Engineer - Web Developer</h4>
<div>
<Row>
<Col lg={3}></Col>
<Col lg={6} className="menu-text">
<ListGroup>
<ListGroup.Item
onClick={event => handleOnClick(event)}
active
>
ABOUT
</ListGroup.Item>
<ListGroup.Item>WORK EXPERIENCE</ListGroup.Item>
<ListGroup.Item>EDUCATION</ListGroup.Item>
<ListGroup.Item>SKILLS</ListGroup.Item>
<ListGroup.Item>CONTACT</ListGroup.Item>
</ListGroup>
</Col>
<Col lg={3}></Col>
</Row>
</div>
</Col>
<Col className="info text-center" lg={8}>
<Container>
<div className="about"></div>
<div
className="work"
ref={ref => {
setRef(ref);
}}
>
<Work />
</div>
<div className="education"></div>
<div
className="skills"
ref={ref => {
setRef(ref);
}}
>
<Skills />
</div>
<div className="contact"></div>
</Container>
</Col>
</Row>
</div>
);
};
export default App;
The ref works fine just with one. If clicked about redirect to skills, but i want to use state like array to work with all references but i'm stuck with this one. Thanks for any help!

Here is a simplified example of using the useRef hook:
import React from "react";
import ReactDOM from "react-dom";
import "./styles.css";
const App = () => {
const work = React.useRef();
const skills = React.useRef();
return (
<div>
<button onClick={() => work.current.scrollIntoView()}>
WORK EXPERIENCE
</button>
<button onClick={() => skills.current.scrollIntoView()}>SKILLS</button>
<div className="another" />
<div className="work" ref={work}>
WORK SECTION
</div>
<div className="skills" ref={skills}>
SKILL SECTIONS
</div>
</div>
);
};
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
