How to toggle class in react, but one component at once(all with the same classes)

let me explain my situation.
I am building a MERN project to my portfolio and I am trying to make a button toggle between the name of an item and a inputfield. So when the user click the pen (edit), it will add a class with the displain:none; in the div with the text coming from the MongoDB data base to hide it and will remove it from the div with the input. I could manage to do it. BUT since the amount of items can inscrease, clicking in one of them cause the toggle in all of them.
It was ok until I send some useState as props to the component.
This is my code from the App.jsx
import React, {useState, useEffect} from "react";
import Axios from "axios";
import "./App.css";
import ListItem from "./components/ListItem";
function App() {
//here are the use states
const [foodName, setFoodName] = useState("");
const [days, setDays] = useState(0);
const [newFoodName, setNewFoodName] = useState("");
const [foodList, setFoodList] = useState([]);
//here is just the compunication with the DB of a form that I have above those components
useEffect(() => {
Axios.get("http://localhost:3001/read").then((response) => {
setFoodList(response.data);
});
}, []);
const addToList = () => {
Axios.post("http://localhost:3001/insert", {
foodName: foodName,
days: days,
});
};
const updateFood = (id) => {
Axios.put("http://localhost:3001/update", {
id: id,
newFoodName: newFoodName,
});
};
return (
<div className="App">
//Here it starts the app with the form and everything
<h1>CRUD app with MERN</h1>
<div className="container">
<h3 className="container__title">Favorite Food Database</h3>
<label>Food name:</label>
<input
type="text"
onChange={(event) => {
setFoodName(event.target.value);
}}
/>
<label>Days since you ate it:</label>
<input
type="number"
onChange={(event) => {
setDays(event.target.value);
}}
/>
<button onClick={addToList}>Add to list</button>
</div>
//Here the form finishes and now it starts the components I showed in the images.
<div className="listContainer">
<hr />
<h3 className="listContainer__title">Food List</h3>
{foodList.map((val, key) => {
return (
//This is the component and its props
<ListItem
val={val}
key={key}
functionUpdateFood={updateFood(val._id)}
newFoodName={newFoodName}
setNewFoodName={setNewFoodName}
/>
);
})}
</div>
</div>
);
}
export default App;
Now the component code:
import React from "react";
//Material UI Icon imports
import CancelIcon from "#mui/icons-material/Cancel";
import EditIcon from "#mui/icons-material/Edit";
//import CheckIcon from "#mui/icons-material/Check";
import CheckCircleIcon from "#mui/icons-material/CheckCircle";
//App starts here, I destructured the props
function ListItem({val, key, functionUpdateFood, newFoodName, setNewFoodName}) {
//const [foodList, setFoodList] = useState([]);
//Here I have the handleToggle function that will be used ahead.
const handleToggle = () => {
setNewFoodName(!newFoodName);
};
return (
<div
className="foodList__item"
key={key}>
<div className="foodList__item-group">
<h3
//As you can see, I toggle the classes with this conditional statement
//I use the same classes for all items I want to toggle with one click
//Here it will toggle the Food Name
className={
newFoodName
? "foodList__item-newName-delete"
: "foodList__name"
}>
{val.foodName}
</h3>
<div
className={
newFoodName
? "foodList__item-newName-group"
: "foodList__item-newName-delete"
}>
//Here is the input that will replace the FoodName
<input
type="text"
placeholder="The new food name..."
className="foodList__item-newName"
onChange={(event) => {
setNewFoodName(event.target.value);
}}
/>
//Here it will confirm the update and toggle back
//Didn't implement this yet
<div className="foodList__icons-confirm-group">
<CheckCircleIcon
className="foodList__icons-confirm"
onClick={functionUpdateFood}
/>
<small>Update?</small>
</div>
</div>
</div>
//here it will also desappear on the same toggle
<p
className={
newFoodName
? "foodList__item-newName-delete"
: "foodList__day"
}>
{val.daysSinceIAte} day(s) ago
</p>
<div
className={
newFoodName
? "foodList__item-newName-delete"
: "foodList__icons"
}>
//Here it will update, and it's the button that toggles
<EditIcon
className="foodList__icons-edit"
onClick={handleToggle}
/>
<CancelIcon className="foodList__icons-delete" />
</div>
</div>
);
}
export default ListItem;
I saw a solution that used different id's for each component. But this is dynamic, so if I have 1000 items on the data base, it would display all of them, so I can't add all this id's.
I am sorry for the very long explanation. It seems simple, but since I am starting, I spent the day on it + searched and tested several ways.

I don't know why I get this, if it is according to the React manual

I tell him I am transferring an event from the component
child ( ItemCount) to the parent component parent ItemDetail the onADD event that only acts if an item is passed to it and when it does, the state becomes true.
The child has an event called add to cart which triggers the event and passes a product counter.
It runs perfectly but it throws me a warning that is the following.
react-dom.development.js:86 Warning: Functions are not valid as a React child. This may happen if you return a Component instead of from render. Or maybe you meant to call this function rather than return it.
Can you tell me the mistake and what I did wrong? from now very grateful
I share the codes Thanks

<br/><h2>{avisarStock}</h2>
Here, you are trying to render a component, but actually avisarStock is a function which sets state and opens an alert. It makes no sense to try to render this function.
It would appear you meant to render stock not avisarStock. This would show your stock state in the <h2>:
<br/><h2>{stock}</h2>

<br/><h2>{avisarStock}</h2> avisarStock is a function, and since Component can be function, react thinks you are doing Component instead of <Component />

React conditional styling in a map function problem

I just want to show toggled item. But all map items showing up. Basically this is the result I'm getting from onclick. I think i need to give index or id to each item but i don't know how to do it. i gave id to each question didn't work.
App.js.
import "./App.css";
import React, { useState, useEffect } from "react";
import bg from "./images/bg-pattern-desktop.svg";
import bg1 from "./images/illustration-box-desktop.svg";
import bg2 from "./images/illustration-woman-online-desktop.svg";
import { data } from "./data";
import Faq from "./Faq";
function App() {
const [db, setDb] = useState(data);
const [toggle, setToggle] = useState(false);
useEffect(() => {
console.log(db);
}, []);
return (
<>
<div className="container">
<div className="container-md">
<div className="faq">
<img src={bg} className="bg" />
<img src={bg1} className="bg1" />
<img src={bg2} className="bg2" />
<div className="card">
<h1>FAQ</h1>
<div className="info">
{db.map((dat) => (
<Faq
toggle={toggle}
setToggle={setToggle}
title={dat.title}
desc={dat.desc}
key={dat.id}
id={dat.id}
/>
))}
</div>
</div>
</div>
</div>
</div>
</>
);
}
export default App;
(map coming from simple data.js file that I created. it includes just id title desc.)
Faq.js
import React from "react";
import arrow from "./images/icon-arrow-down.svg";
const Faq = ({ toggle, setToggle, title, desc, id }) => {
return (
<>
{" "}
<div className="question" onClick={() => setToggle(!toggle)}>
<p>{title}</p>
<img src={arrow} className={toggle ? "ikon aktif" : "ikon"} />
</div>
<p className="answer border">{toggle ? <>{desc}</> : ""}</p>
</>
);
};
export default Faq;

You need to store the index value of the toggle item.
You can modify the code with only 2 lines with the existing codebase.
import "./App.css";
import React, { useState, useEffect } from "react";
import bg from "./images/bg-pattern-desktop.svg";
import bg1 from "./images/illustration-box-desktop.svg";
import bg2 from "./images/illustration-woman-online-desktop.svg";
import { data } from "./data";
import Faq from "./Faq";
function App() {
const [db, setDb] = useState(data);
const [toggle, setToggle] = useState(-1); //Modify Here
useEffect(() => {
console.log(db);
}, []);
return (
<>
<div className="container">
<div className="container-md">
<div className="faq">
<img src={bg} className="bg" />
<img src={bg1} className="bg1" />
<img src={bg2} className="bg2" />
<div className="card">
<h1>FAQ</h1>
<div className="info">
{db.map((dat, index) => ( //Modify Here
<Faq
toggle={index === toggle} //Modify Here
setToggle={() => setToggle(index)} //Modify Here
title={dat.title}
desc={dat.desc}
key={dat.id}
id={dat.id}
/>
))}
</div>
</div>
</div>
</div>
</div>
</>
);
}
export default App;
import React from "react";
import arrow from "./images/icon-arrow-down.svg";
const Faq = ({ toggle, setToggle, title, desc, id }) => {
return (
<>
{" "}
<div className="question" onClick={setToggle}>
<p>{title}</p>
<img src={arrow} className={toggle ? "ikon aktif" : "ikon"} />
</div>
<p className="answer border">{toggle ? <>{desc}</> : ""}</p>
</>
);
};
export default Faq;

You will need state for each toggle. Here is a minimal verifiable example. Run the code below and click ⭕️ to toggle an item open. Click ❌ to close it.
function App({ faq = [] }) {
const [toggles, setToggles] = React.useState({})
const getToggle = key =>
Boolean(toggles[key])
const setToggle = key => event =>
setToggles({...toggles, [key]: !getToggle(key) })
return faq.map((props, key) =>
<Faq key={key} {...props} open={getToggle(key)} toggle={setToggle(key)} />
)
}
function Faq({ question, answer, open, toggle }) {
return <div>
<p>
{question}
<button onClick={toggle} children={open ? "❌" : "⭕️"} />
</p>
{open && <p>{answer}</p>}
</div>
}
const faq = [
{question: "hello", answer: "world"},
{question: "eat", answer: "vegetables"}
]
ReactDOM.render(<App faq={faq} />, document.querySelector("#app"))
p { border: 1px solid gray; padding: 0.5rem; }
p ~ p { margin-top: -1rem; }
button { float: right; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.14.0/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.14.0/umd/react-dom.production.min.js"></script>
<div id="app"></div>

Instead of doing this (in App component):
const [db, setDb] = useState(data);
const [toggle, setToggle] = useState(false);
you can write an useState hook like below to combine the two hooks and assign an isOpened property for each Faq element:
const [db, setDb] = useState(data.map(value=>{return {...value, isOpened:false}}));
and then right here you can do this (as the child of <div className="info">):
{db.map((dat, index) => (
<Faq
toggle={dat.isOpened}
setToggle={() => toggleById(dat.id)}
title={dat.title}
desc={dat.desc}
key={dat.id}
id={dat.id}
/>
))}
Also you need to declare toggleById function in App component:
const toggleById = (id) => {
const newDb = db.map(dat=>{
if(dat.id==id){
return {...dat,isOpened:!dat.isOpened}
}
return dat;
});
setDb(newDb);
}
and since setToggle prop of Faq, calls toggleById by its defined parameter, there is no need to do this in Faq component:
<div className="question" onClick={() => setToggle(!toggle)}>
you can simply write:
<div className="question" onClick={setToggle}>

how to send a parameter from a file to another in react

I'm building a pokedex website and I have pokemon cards with some data displayed in them from a JSON file and when you click on one of them you have a modal view that appears with more detailed data.
So in the modal view I want only the detailed data of the card I just clicked on it.
I have no idea how to do that if anyone can help, thanks.
This is Modal.tsx where I initialize my modal view, this where I want to get the pokemon name from Card.tsx (cf below) to be able to know which card was clicked :
import '../components/Modal.css';
import Data from '../pokemons.json';
import React from 'react';
export const Modal = ({showModal} : {showModal: boolean}) => {
return (
<>{showModal ? (
<div className="modal-back">
<div className="modal-container">
MODAL VIEW
</div>
</div>
): null}</>
);
};
This is Card.tsx where I handle the cards and where I call the modal view :
import Data from "../pokemons.json"
import '../components/Card.css'
import {FiThumbsUp} from "react-icons/fi"
import {useState} from 'react';
import {Modal} from './Modal';
function Card() {
const [showModal, setShowModal] = useState(false);
return(
<div className="cards">
{Data.map(card => {
return(
<div className="card-box" onClick={() => setShowModal(true)}>
<img src={card.img} alt="" />
<div className="text">
<div className="first-line">
<p className="id">{card.id}</p>
<p>{card.name}</p>
</div>
<div className="type-container">
{card.type.map((type, index) => {
return(
<div className="type" key={index}>
<p className={type}>{type}</p>
</div>
);
}) }
</div>
</div>
<div className="icon-circle">
<FiThumbsUp className="icon" color="#e5e5e5" size="18px"/>
</div>
</div>
);
}) }
<Modal showModal={showModal}></Modal>
</div>
);
}
export default Card;

You can pass selected card data as prop in the modal. You also need to update prop type as it only accepts one parameter.
Your Modal component will look like this:
interface ICard {
name: string,
...
}
interface props {
showModal: boolean;
card: ICard
}
export const Modal: FC<props> = ({showModal, card}) => {
return (
<>{showModal ? (
<div className="modal-back">
<div className="modal-container">
MODAL VIEW
</div>
<p>{card.name}</p>
</div>
): null}</>
);
};
You also need to update Card component to pass props. Make sure you're storing selected card data.
<Modal showModal={showModal} card={card} />

React - how to pass data into Modal (bootstrap)

I'm trying to pass data into Modal (bootstrap) popup and display some data.
I have a list of orders with a button 'display info', and every button that i press should display on the popup (Modal) diffrent data.
My question is how should i pass the data to the Modal?
this line <Button variant="primary" onClick={() => {this.handleModal(index)}}> Items info</Button> should trigger the Modal. In the handleModal function it passes the order index. And then i update the index on the setState of the handleModal function.
The Modal open but nothing passes to it.
I'm not sure that this is the correct way of doing it.
Also the Modal is inside the loop of the filteredOrders, should i move the Modal outside the loop?
And if yes, how should i do that and where?
import React, {useState} from 'react';
import './App.scss';
import {createApiClient, Item, Order} from './api';
import Modal from 'react-bootstrap/Modal';
import Button from 'react-bootstrap/Button';
import 'bootstrap/dist/css/bootstrap.min.css'
export type AppState = {
orders?: Order[],
search: string;
show:boolean;
item?: Item,
order_id: number,
}
const api = createApiClient();
export class App extends React.PureComponent<{}, AppState> {
state: AppState = {
search: '',
show:false,
order_id: 0,
};
searchDebounce: any = null;
async componentDidMount() {
this.setState({
orders: await api.getOrders()
});
}
async getItem(itemID: string){
this.setState({
item: await api.getItem(itemID)
});
}
render() {
const {orders} = this.state;
return (
<main>
<h1>Orders</h1>
<header>
<input type="search" placeholder="Search" onChange={(e) => this.onSearch(e.target.value)}/>
</header>
{orders ? <div className='results'>Showing {orders.length} results</div> : null}
{orders ? this.renderOrders(orders) : <h2>Loading...</h2>}
</main>
)
}
handleModal(index: number)
{
this.setState({
show:true,
order_id: index,
})
}
handleClose () {
this.setState({show: false})
}
renderOrders = (orders: Order[]) => {
const filteredOrders = orders
.filter((order) => (order.customer.name.toLowerCase() + order.id).includes(this.state.search.toLowerCase()));
const requiredItem = this.state.order_id;
const modelData = filteredOrders[requiredItem];
return (
<div className='orders'>
{filteredOrders.map((order,index) => (
<div className={'orderCard'}>
<div className={'generalData'}>
<h6>{order.id}</h6>
<h4>{order.customer.name}</h4>
<h5>Order Placed: {new Date(order.createdDate).toLocaleDateString()}</h5>
</div>
<div className={'fulfillmentData'}>
<h4>{order.itemQuantity} Items</h4>
<img src={App.getAssetByStatus(order.fulfillmentStatus)}/>
{order.fulfillmentStatus !== 'canceled' &&
<a href="#" onClick={() => this.ChangeStatus(order)}>Mark
as {order.fulfillmentStatus === 'fulfilled' ? 'Not Delivered' : 'Delivered'}</a>
}
</div>
<div className={'extraData'}>
<Button variant="primary" onClick={() => {this.handleModal(index)}}> Items info</Button>
<Modal show={this.state.show} >
{/*{console.log(modelData)}*/}
{/*<Modal.Header closeButton>*/}
{/* <Modal.Title>Item Info</Modal.Title>*/}
{/*</Modal.Header>*/}
<Modal.Body>
{ console.log(modaelData) }
</Modal.Body>
<Modal.Footer>
<Button onClick={() =>{ this.handleClose()}}>
Close
</Button>
</Modal.Footer>
</Modal>
</div>
<div className={'paymentData'}>
<h4>{order.price.formattedTotalPrice}</h4>
<img src={App.getAssetByStatus(order.billingInfo.status)}/>
</div>
</div>
))}
</div>
)
};
}
export default App;

I don't think you need to pass data to the Modal, but rather compose the Modal with the data in the first place. It is currently empty. Then you can continue to hide/show the complete Modal with handleModal.
