How can I use onClick on stateless component in React?

I want to use onClick on a stateless compoenent but it's reject an error like : onClick listener to be a function, instead got a value of object type.
I need to show and hide component on click.
Example when I click on the <ResultCard/> component I want to hide him and show <ResultDetail/>
State React Component :
import React, { Component } from "react";
import ResultCard from "./ResultCard";
import "../../assets/css/Result.css";
import Spinner from "../Spinner";
import { getApiToken, getParisByPrice } from "../../services/api";
import Modal from "../Modal";
import "../../assets/css/BudgetEntry.css";
import modify from "../../assets/images/modify.png";
import ResultDetail from "./ResultDetail";
class Results extends Component {
state = {
priceValue: "",
showResult: true
};
showResultDetail = () => {
this.setState({ showResult: false });
};
closeResultDetails = () => {
this.setState({ showResult: true });
};
render() {
return (
<div className="results-container">
{this.state.loading ? (
<Spinner />
) : (
<div className={"row"}>
{this.state.showResult ?
(
this.state.paris.map(details => (
<ResultCard
key={details.id}
id={details.id}
showResultDetail={this.showResultDetail}
prefix={details.prefix}
costPerDay={details.average_cost_per_day}
logoSports={details.infrastructure.map(home =>
home.logo_path.map(path_image => (
<img
src={path_image}
alt="icon-sports"
style={{ width: 20 }}
key={path_image}
/>
))
)}
/>
))
)
:
(
<ResultDetail closeResultDetail={this.closeResultDetails}/>
)
}
</div>
)}
</div>
);
}
}
export default Results;
ResultCard (who is stateless component):
import React from 'react';
import '../../assets/css/ResultCard.css';
const ResultCard = ({prefix, costPerDay, logoSports, showResultDetail, id}) => {
return (
<div className="card" onClick={showResultDetail} id={id}>
<p style={{margin:5}}>{prefix}</p>
<p style={{margin:1}}>arrondissement</p>
<p>{costPerDay} $</p>
{logoSports}
</div>
)
};
export default ResultCard;
ResultDetail (who is stateless component):
import React from 'react';
const ResultDetail = (closeResultDetail) => (
<div onClick={closeResultDetail}>
<p>Result detail</p>
</div>
)
export default ResultDetail;
thank for your help

The issue is here
const ResultDetail = (closeResultDetail) => (
You need to destructure it from the props object like this:
const ResultDetail = ({closeResultDetail}) => (
Or use it from props directly like this:
const ResultDetail = (props) => (
<div onClick={props.closeResultDetail}>
...

in your state component
showResultDetail = () => {
this.setState({ showResult: false });
};
render() {
....
<ResultCard
....
show={this.state.showResult}
//defer the execution of the method
onClick={(e) => this.showResultDetail(e)}/>
}
resultCard.js
const ResultCard = ({prefix, costPerDay, logoSports, showResultDetail, id, show}) => {
if(show)
return (
<div className="card" onClick={showResultDetail} id={id}>
<p style={{margin:5}}>{prefix}</p>
<p style={{margin:1}}>arrondissement</p>
<p>{costPerDay} $</p>
{logoSports}
</div>
);
};

in Results you define
showResultDetail = () => {
this.setState( {showResult: false });
};
as a function without arguments. You then pass
showResultDetail={(e) => this.showResultDetail(e)}
as a function with an event argument to your ResultCard. If you change that to
showResultDetail={this.showResultDetail}
your problem might already be fixed.
Edit: Here is a minimal snippet that does what you're looking for, I think.
const ResultCard = ({showResultDetail, show}) => {
return <div className="card" onClick={showResultDetail}>{show?'Click me!':''}</div>
};
class Results extends React.Component {
state = {
priceValue: "",
showResult: true
};
showResultDetail = () => {
this.setState({ showResult: false });
};
render() {
return <ResultCard show={this.state.showResult}
showResultDetail={this.showResultDetail}/>
}
}
ReactDOM.render(<Results/>, document.getElementById('root'))
.card {
width: 200px;
height: 50px;
background: lightgray;
text-align: center;
line-height: 50px;
}

How to render the elements before to filter elements with ReactJS?

I'm doing a project which does a get of the json-server, and render them on the screen.
But when I added a filtering function on it, it only renders after I type a name to filter. I wanted him to render everyone and make the filter.
My Body.js (Where is my function of render):
import React from 'react';
import './Body.css';
import { Link } from "react-router-dom";
class Body extends React.Component {
constructor(props) {
super(props);
this.state = {
input: "",
employeeBody: this.props.employee,
}
}
getName = () => {
const { employee, add } = this.props;
const {employeeBody} = this.state;
return employee.map(name => (
<div className='item'>
<Link className="link" to={`/user/${name.id}`}>
<div onClick={() => add(name)} key={name.id}>
<img className="img"
src={`https://picsum.photos/${name.id}`}
/>
</div>
<h1 className="name2"> {name.name} </h1>
</Link>
</div>
));
};
---
getValueInput = (evt) => {
const inputValue = evt.target.value;
this.setState({ input: inputValue });
this.filterNames(inputValue);
console.log(this.state.employeeBody)
}
filterNames (inputValue) {
const { employee } = this.props;
this.setState({
employeeBody: employee.filter(item =>
item.name.includes(inputValue))
});
}
---
render() {
return (
<div>
<div className="body">
{this.getName()}
</div>
<div className='input'>
<input type="text" onChange={this.getValueInput} />
</div>
</div>
)
}
}
export default Body;
My App.js (Where i get the state by get of axios.):
import React from 'react';
import {
BrowserRouter as Router,
Route
} from "react-router-dom";
import './App.css';
import axios from 'axios';
import Body from './Body';
import User from './User';
import Header from './Header';
class AppRouter extends React.Component {
state = {
employeeCurrent: [],
employee: []
};
componentDidMount() {
axios
.get("http://127.0.0.1:3004/employee")
.then(response => this.setState({
employee: response.data
}));
}
add = name => {
this.setState(prevState => {
const copy = prevState.employeeCurrent.slice(1);
copy.push(name);
return {
employeeCurrent: copy
};
});
};
render() {
return ( <
Router >
<
div className = "router" >
<
Header / >
<
Route exact path = "/"
render = {
props => ( <
Body { ...props
}
add = {
this.add
}
employee = {
this.state.employee
}
employeeCurrent = {
this.state.employeeCurrent
}
/>
)
}
/> <
Route path = "/user/:id"
component = {
props => ( <
User { ...props
}
employee = {
this.state.employee
}
employeeCurrent = {
this.state.employeeCurrent
}
/>
)
}
/> <
/div> <
/Router>
);
}
}
export default AppRouter;
Someone would can help me ?

You should filter in the render method.
render() {
const { employee: employees } = this.props; // rename the variable {employee} to plural {employees}, it has more sense.
const { input } = this.state;
return (
<div>
<div className="body">
{employees
.filter(employee => employee.name.includes(input))
.map(employee => {
<div className='item'>
<Link className="link" to={`/user/${employee.id}`}>
<div onClick={() => add(employee)} key={employee.id}>
<img className="img"
src={`https://picsum.photos/${employee.id}`}
/>
</div>
<h1 className="name2"> {employee.name} </h1>
</Link>
</div>
})}
</div>
<div className='input'>
<input type="text" onChange={(e) => this.setState({ input: e.target.value })} />
</div>
</div>
);
}
Remember that the method includes is case sensitive, it should be lowerCase it before to compare.
P.S.: You could also create a variable / component / function and render split all the "logic" of rendering there.

How to apply load more button to push this.state in React

The purpose of implementing <a className="button" onClick={this.loadMore}>Load more news</a> button is to take more objects with API and show without refresh the page. Still not sure the way to implementing setState method is ideal or not
this.setState({
newsData: [...this.state.newsData, ...responseJson]
})
App.js
import React from 'react';
import { Newslist } from './newslist/Newslist';
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
page: 1,
newsData: ''
}
}
componentDidMount() {
this.page = 1;
this.requestNews();
}
requestNews () {
console.log('koooy');
fetch('http://localhost:3000/api/?page='+this.page)
.then((response) => response.json())
.then((responseJson) => {
this.setState({
newsData: [...this.state.newsData, ...responseJson]
})
})
.catch((error) => {
console.error(error);
});
}
loadMore = () => {
this.requestNews();
}
render() {
return (
<main className="main">
<h1>Hello mate !</h1>
<Paggination />
{ this.state.newsData.length
? <Newslist currentNews={this.state.newsData} loadMoreData={this.loadMore} />
: <p>Loading...</p>
}
</main>
);
}
}
export default App;
Newslist.js
import React from 'react';
export class Newslist extends React.Component {
loadMore = () => {
event.preventDefault();
this.props.loadMoreData();
}
render () {
const newsInList = this.props.currentNews.map(newsDetails => {
return (
<section className="media" key={newsDetails.id}>
{newsDetails.image && <figure className="media-figure">
<img src={newsDetails.image} />
</figure>}
<div className="media-body">
<h3 className="media-title">{newsDetails.header}</h3>
<p>{newsDetails.content}</p>
</div>
</section>
);
});
return (
<div>
{newsInList}
<a className="button" onClick={this.loadMore}>Load more news</a>
</div>
);
}
}

What you have done seems reasonable. Basically, make sure you know your current news page/offset. When you make the API request, send the page/offset with the request and append the new use to the head or tail of the array.
I noticed a suggestion about the usage of Redux, Redux is rather complicated and this is a very simple issue, no need for it here.

react-stripe-elements Error: You must provide a Stripe Element or a valid token type to create a Token

I am using react-stripe-elements to create a token for payments. However, according to the documentation when the card form is wrapped in the Elements component it should automatically pickup which stripe elements to tokenize.
However, in this case we are presented with the error
You must provide a Stripe Element or a valid token type to create a Token.
Here is the code:
import React from 'react';
import {CardCVCElement, CardExpiryElement, CardNumberElement, PostalCodeElement, StripeProvider, Elements} from 'react-stripe-elements';
class CheckoutForm extends React.Component {
constructor(props) {
super(props);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleSubmit(ev) {
ev.preventDefault();
this.props.stripe.createToken({email: 'test#test.com'}).then(({token }) => {console.log('Received Stripe token:', token)});
}
render() {
return (
<form onSubmit={this.handleSubmit}>
<label>
Card details
<CardNumberElement />
<CardExpiryElement />
<CardCVCElement />
<PostalCodeElement />
</label>
<button>Confirm order</button>
</form>
);
}
}
class App extends React.Component {
constructor() {
super();
this.state = { stripe: null };
}
componentDidMount() {
this.setState({ stripe: window.Stripe('test_key') });
}
render() {
return (
<StripeProvider stripe={this.state.stripe}>
<Elements>
<CheckoutForm stripe={this.state.stripe} />
</Elements>
</StripeProvider>
);
}
}
export default App;
According to the documentation the following should be true:
'Within the context of Elements, this call to createToken knows which Element to tokenize, since there's only one in this group.'
However, this doesn't seem to be the case. I have also tried using the single 'Card Element' and have not found any success in doing so.

It turns out I never managed to solve the issue using react-stripe-elements. I ended using the standard JS version (from the stripe documentation). Here is my current working solution:
import React from 'react';
class CheckoutForm extends React.Component {
constructor(props) {
super(props);
this.handleSubmit = this.handleSubmit.bind(this);
this.state = {
elements: null,
card: null
};
}
componentWillReceiveProps() {
this.setState({ elements: this.props.stripe.elements() }, () => {
this.setState({ card: this.state.elements.create('card') }, () => {
this.state.card.mount('#card-element');
});
});
}
handleSubmit(ev) {
ev.preventDefault();
this.props.stripe.createToken(this.state.card).then((token) => {
console.log('Received Stripe token:', token);
});
}
render() {
return (
<form onSubmit={this.handleSubmit}>
<div className="row">
<label >
Credit or debit card
</label>
<div id="card-element"/>
<div id="card-errors" role="alert"/>
</div>
<button>Submit Payment</button>
</form>
);
}
}
class App extends React.Component {
constructor() {
super();
this.state = {stripe: window.Stripe('test_key')};
}
render() {
return (
<CheckoutForm stripe={this.state.stripe}/>
);
}
}
export default App;

In the comments they rightly say you need to use the HOC injectStripe.
The docs for stripe.createToken mention that you need to pass the element you wish to tokenize data from.
Also from the github repo README:
⚠️ NOTE injectStripe cannot be used on the same element that renders the Elements component; it must be used on the child component of Elements. injectStripe returns a wrapped component that needs to sit under but above any code where you'd like to access this.props.stripe.
In my specif case I was using a Mobx store and I needed to handle createToken and my form submission in the same place.
Even though I had a reference to stripe since initialisation it didn't work.
The createToken call needs to come from a component child of Elements and with stripe injected.
I ended up having:
#inject('signupStore')
#observer
class CardInput extends React.Component {
componentDidMount() {
const { signupStore } = this.props;
const handleCard = async name => {
return await this.props.stripe.createToken({ name: name });
};
signupStore.assignHandleCard(handleCard);
}
render() {
return (
<label>
Card details
<CardElement style={{ base: { fontSize: '18px' } }} />
</label>
);
}
}
export default injectStripe(CardInput);
Passing the handler back to the store, and then using it from there.
Part of signupStore:
#action
async submitForm(formValues) {
if (this.stripe && this.handleCard) {
const tokenResponse = await this.handleCard(
`${formValues.firstName} ${formValues.lastName}`
);
runInAction(() => {
console.log('Card token received ', tokenResponse);
if (tokenResponse) {
this.cardToken = tokenResponse.token.id;
formValues.cardToken = this.cardToken;
}
});
const response = await request.signup.submit(formValues);
return response;
}
return null;
}

With the new #stripe/react-stripe-js library it's a bit different. We need to use ElementsConsumer component. Load stripe using loadStripe method and use Elements component to use your form with Stripe.
Here is a basic example.
import { Elements, loadStripe } from "#stripe/react-stripe-js"
const stripePromise = loadStripe(STRIPEKEY)
<Elements stripe={stripePromise}>
<CardForm />
</Elements>
CardForm.js
import {
CardNumberElement,
CardExpiryElement,
CardCvcElement,
ElementsConsumer,
} from "#stripe/react-stripe-js"
const StripeForm = ({ stripe, elements }) => {
const handleSubmit = async () => {
if (!stripe || !elements) {
return
}
const cardNumberElement = elements.getElement(CardNumberElement)
const res = await stripe.createToken(cardNumberElement)
}
return (
<form>
<div>
<label htmlFor="cardNumber">Card Number</label>
<div>
<CardNumberElement />
</div>
</div>
<div>
<label htmlFor="cardName">Card Name</label>
<input
type="text"
name="cardName"
required
placeholder="Please Enter"
pattern="[A-Za-z]"
/>
</div>
<div>
<label htmlFor="expDate">Exp. Date</label>
<div>
<CardExpiryElement />
</div>
</div>
<div>
<label htmlFor="CVC">CVC</label>
<div>
<CardCvcElement />
</div>
</div>
</form>
)
}
const CardForm = () => {
return (
<ElementsConsumer>
{({ stripe, elements }) => (
<StripeForm stripe={stripe} elements={elements} />
)}
</ElementsConsumer>
)
}
export default CardForm

React js it's working for me
Card component , Get error , Card Detail and Generate Token
import React, { useState, useEffect } from "react";
import {loadStripe} from '#stripe/stripe-js';

});
console.log("paymentMethod",paymentMethod);

Unmount component on click in child component button // React

I am struggling with successfully removing component on clicking in button. I found similar topics on the internet however, most of them describe how to do it if everything is rendered in the same component. In my case I fire the function to delete in the child component and pass this information to parent so the state can be changed. However I have no idea how to lift up the index of particular component and this is causing a problem - I believe.
There is a code
PARENT COMPONENT
export class BroadcastForm extends React.Component {
constructor (props) {
super(props)
this.state = {
numberOfComponents: [],
textMessage: ''
}
this.UnmountComponent = this.UnmountComponent.bind(this)
this.MountComponent = this.MountComponent.bind(this)
this.handleTextChange = this.handleTextChange.bind(this)
}
MountComponent () {
const numberOfComponents = this.state.numberOfComponents
this.setState({
numberOfComponents: numberOfComponents.concat(
<BroadcastTextMessageForm key={numberOfComponents.length} selectedFanpage={this.props.selectedFanpage}
components={this.state.numberOfComponents}
onTextChange={this.handleTextChange} dismissComponent={this.UnmountComponent} />)
})
}
UnmountComponent (index) {
this.setState({
numberOfComponents: this.state.numberOfComponents.filter(function (e, i) {
return i !== index
})
})
}
handleTextChange (textMessage) {
this.setState({textMessage})
}
render () {
console.log(this.state)
let components = this.state.numberOfComponents
for (let i = 0; i < components; i++) {
components.push(<BroadcastTextMessageForm key={i} />)
}
return (
<div>
<BroadcastPreferencesForm selectedFanpage={this.props.selectedFanpage}
addComponent={this.MountComponent}
textMessage={this.state.textMessage} />
{this.state.numberOfComponents.map(function (component) {
return component
})}
</div>
)
}
}
export default withRouter(createContainer(props => ({
...props
}), BroadcastForm))
CHILD COMPONENT
import React from 'react'
import { createContainer } from 'react-meteor-data'
import { withRouter } from 'react-router'
import { BroadcastFormSceleton } from './BroadcastForm'
import './BroadcastTextMessageForm.scss'
export class BroadcastTextMessageForm extends React.Component {
constructor (props) {
super(props)
this.handleChange = this.handleChange.bind(this)
this.unmountComponent = this.unmountComponent.bind(this)
}
handleChange (e) {
this.props.onTextChange(e.target.value)
}
unmountComponent (id) {
this.props.dismissComponent(id)
}
render () {
console.log(this.props, this.state)
const textMessage = this.props.textMessage
return (
<BroadcastFormSceleton>
<div className='textarea-container p-3'>
<textarea id='broadcast-message' className='form-control' value={textMessage}
onChange={this.handleChange} />

</div>
</BroadcastFormSceleton>
)
}
}
export default withRouter(createContainer(props => ({
...props
}), BroadcastTextMessageForm))
I am having problem with access correct component and delete it by changing state. Any thoughts how to achieve it?

Please fix the following issues in your code.
Do not mutate the state of the component. Use setState to immutably change the state.
Do not use array index as the key for your component. Try to use an id field which is unique for the component. This will also help with identifying the component that you would need to unmount.

Try something like this. As mentioned before, you don't want to use array index as the key.
class ParentComponent extends React.Component {
constructor() {
this.state = {
// keep your data in state, as a plain object
textMessages: [
{
message: 'hello',
id: '2342334',
},
{
message: 'goodbye!',
id: '1254534',
},
]
};
this.handleDeleteMessage = this.handleDeleteMessage.bind(this);
}
handleDeleteMessage(messageId) {
// filter by Id, not index
this.setState({
textMessages: this.state.textMessages.filter(message => message.id !== messageId)
})
}
render() {
return (
<div>
{this.state.textMessages.map(message => (
// Use id for key. If your data doesn't come with unique ids, generate them.
<ChildComponent
key={message.id}
message={message}
handleDeleteMessage={this.handleDeleteMessage}
/>
))}
</div>
)
}
}
function ChildComponent({message, handleDeleteMessage}) {
function handleClick() {
handleDeleteMessage(message.id)
}
return (
<div>
{message.message}
<button
onClick={handleClick}
>
Delete
</button>
</div>
);
}
