So I have mapped data from array into a carousel, creating total of twenty carousel items. Each element has "same" button embedded into them. I want to send the relative data from each element into the modal when that button is clicked and honestly I have no idea even where to start from.
This is the code I have currently for this component:
Edit: highlighted the data I would like to pass into the relative modal.
import React from 'react';
import {connect} from 'react-redux';
import Slider from 'react-slick';
import Modal from 'react-modal';
import { FontAwesomeIcon } from '#fortawesome/react-fontawesome';
import { fetchActionM } from '../../store/actions/moviepageActions';
const img_url = 'https://image.tmdb.org/t/p/original';
const customStyles = {
content : {
top : '50%',
left : '50%',
right : 'auto',
bottom : 'auto',
marginRight : '-50%',
transform : 'translate(-50%, -50%)',
color : 'white',
background: '#080a0a none repeat scroll 0% 0%',
width: '600px',
}
};
Modal.setAppElement('#root')
class ActionMov extends React.Component{
constructor() {
super();
this.state = {
modalIsOpen: false
};
this.openModal = this.openModal.bind(this);
this.afterOpenModal = this.afterOpenModal.bind(this);
this.closeModal = this.closeModal.bind(this);
}
openModal() {
this.setState({modalIsOpen: true});
}
afterOpenModal(){
this.subtitle.style.color = '#f00';
}
closeModal(){
this.setState({modalIsOpen: false});
}
render(){
//send same mapped data from this into the modal when clicked on the button <FontAwesomeIcon onClick....
let action;
if(this.props.action.length > 0){
action = this.props.action[0].results.map(ac => (
<div className='sliderbox' key={ac.id}>
<div className='text-block'>
<h5 className='sliderTitle'>{ac.title}</h5>
<FontAwesomeIcon onClick={() => this.openModal({ac})} icon="plus-circle" className='sliderIcon' />
{/* I need same data from these two be passed into the relative modal */}
<p className='sliderRelease'>{ac.release_date}</p>
<p className='sliderVote'>{ac.vote_average}</p>
{/* Just highlighting this area */}
</div>
<img className='sliderImg' src={`${img_url}${ac.poster_path}`} alt={ac.title} />
</div>
));
}
const settings = {
dots: true,
infinite: true,
speed: 500,
slidesToShow: 6,
slidesToScroll: 3,
draggable: true,
};
return (
<div>
<Slider {...settings}>
{action}
</Slider>
<Modal
isOpen={this.state.modalIsOpen}
onAfterOpen={this.afterOpenModal}
onRequestClose={this.closeModal}
style={customStyles}
contentLabel='Movies modal'
>
{
//Would like to print relative data here
}
<h2 ref={subtitle => this.subtitle = subtitle}>TITLE GOES HERE</h2>
<div>
<p>Id: {`<id goes here>`}</p>
<h5 className='modalRelease'>Released: {`<release date goes here>`}</h5>
<h5 className='modalVote'>Rating: {`<rating goes here>`}</h5>
</div>
<button className='modalClose' onClick={this.closeModal}>X</button>
</Modal>
</div>
)
}
}
const mapStateToProps = (state) => {
return {
action: state.movies.actions
}
}
export default connect(mapStateToProps)(ActionMov);
On click of the button you can set it to the state and can access inside the modal.
First let's initialize it inside the constructor
constructor() {
super();
this.state = {
modalIsOpen: false,
movie: {
id: '', release: '', rating: ''
}
};
this.openModal = this.openModal.bind(this);
this.afterOpenModal = this.afterOpenModal.bind(this);
this.closeModal = this.closeModal.bind(this);
}
Now lets set it up on onClick event, you are actually passing the object to openModal method
openModal(movie) {
this.setState({
modalIsOpen: true,
movie: movie
});
}
Now you are good to access it inside the modal
<Modal
isOpen={this.state.modalIsOpen}
onAfterOpen={this.afterOpenModal}
onRequestClose={this.closeModal}
style={customStyles}
contentLabel='Movies modal'
>
{
//Would like to print relative data here
}
<h2 ref={subtitle => this.subtitle = subtitle}>TITLE GOES HERE</h2>
<div>
<p>Id: {this.state.movie.id}</p>
<h5 className='modalRelease'>Released: {this.state.movie.release}</h5>
<h5 className='modalVote'>Rating: {this.state.movie.rating}</h5>
</div>
<button className='modalClose' onClick={this.closeModal}>X</button>
</Modal>

I am using jquery with React. and when I want to use $(.myclass).resizable(). I got an error:use jquery in React and get jquery_1.default(...).resizable is not a function.
here is the demo:
https://stackblitz.com/edit/react-modal-rnd-2?file=rnd.js
import React from 'react';
import { render } from 'react-dom';
import { Modal, ModalHeader, ModalBody, ModalFooter } from 'reactstrap';
import $ from 'jquery';
export default class RND extends React.Component {
constructor() {
super();
$('.modal-content').resizable({
//alsoResize: ".modal-dialog",
minHeight: 300,
minWidth: 300
});
$('.modal-dialog').draggable();
$('#myModal').on('show.bs.modal', function() {
$(this)
.find('.modal-body')
.css({
'max-height': '100%'
});
});
}
modalClose = () => {
this.setState({
modalShow: false
});
};
onStart = () => {
console.log('here');
};
render() {
return (
<Modal
isOpen={this.state.showModal}
toggle={() => {
this.setState({ showModal: false });
this.modalClose();
}}
style={{
minWidth: '30rem',
border: '0.1rem solid green'
}}
>
<ModalHeader
className="modal-header bg-primary modal-title text-white"
toggle={() => {
this.setState({ showModal: false });
this.modalClose();
}}
>
<h2> Header </h2>
</ModalHeader>
<ModalBody>
<div className="form-group row">
<div className="FormRow col-sm-12">
<span>Body data </span>
</div>
</div>
</ModalBody>
</Modal>
);
}
}
what I want is to make the popup modal resizable and draggable.it also works for me if there is a way to achieve it without jquery.
I've found a solution.
step1:
npm i jquery-ui
step2:
add these sources in jsx file
import 'jquery-ui/themes/base/resizable.css';
import 'jquery-ui/themes/base/draggable.css';
require('jquery-ui/ui/version');
require('jquery-ui/ui/plugin');
require('jquery-ui/ui/widget');
require('jquery-ui/ui/widgets/mouse');
require('jquery-ui/ui/widgets/resizable');
require('jquery-ui/ui/widgets/draggable');
and then you can use jquery-ui function.
Using React.Js, I created a delete function to delete an item from a table. the delete is working fine but what I want to do is that after deleting I want the tables to be dynamically updated to show only the items left. Now after the delete I have to refresh manually the page or go to another page and comeback to see the items left after the delete
This is the code built so far :
import React, { Component } from "react";
import { Card, Button, Select,/* message, */ Form, Tooltip } from "antd";
import extraitMP3 from "./data";
import { arrayMove, SortableHandle } from "react-sortable-hoc";

const VisibiliteFormMp3 = Form.create()(ListExtrait);
const mapStateToProps = ({ comedien }) => {

}
};
export default connect(
mapStateToProps,
{
userSignOut,
getExtraitMp3,
hideMessageUpdate,
showUpdateLoader,
updateMp3Visibilite
})(VisibiliteFormMp3);
extraitMP3 is an object of objects that's why I used Object.keys(extraitMP3)
I didn't know how to update the state correctly.
this is the view :
You should put your data in state and then change the state. After changing the state the page automatically re-rendered and changed data of your state will be shown.
So in your delete function simply delete your chosen data and give your remaining data to your state.
Hope this helps, feel free to ask questions if I couldn't explain myself clearly.
I believe you can do this by calling something like and then just call this from within your delete
refreshMp3(){
this.setState({getExtraitMp3: !this.state.getExtraitMp3});}
One of the ideas of React is to make the functionality you ask for simple to implement and it would update automatically. I'm going to abstract a bit from your example. Think about your data in terms of what updates along with the UI. This way we can simplify your component. You have some items that you put in a table. Each item is a row and can be inside an array. We put that array in the state.
class ListExtrait extends Component {
constructor() {
super();
this.state = {
rowsForTable: [...],
somethingElse...
}
...
Then in the JSX in the render method you can render the table rows using map:
rowsForTable.map(item => <div/li/whatever>{item.name or something else}</div>
This way whenever an item is gone from rowsForTable the component will automatically update it's view and the table rows will be up to date.
You can simply call the function while clicking the delete button say deleteHandler. On that function call the api you have made to delete the item and then after successfull delete again call the api that will show the item from database after certain time interval.
Code:
import React, { Component } from 'react'
export default class show_schedule extends Component {
render() {
state={
}
show_item_after_delete=()=>{
setTimeout(()=>{
axios.get(`http://127.0.0.1:8000/account/api/show_item/`).then(res=>{
console.log('delete schedule data ',res.data)
})
},500)
}
deleteHandler=()=>{
axios.delete(`http://127.0.0.1:8000/account/api/delete_item/${id}`).then(res=>{
console.log(res.data)
})
this.show_item_after_delete()
}
return (
<div>
<button onClick={this.deleteHandler}>Delete</button>
</div>
)
}
}
So I have this big messy component, I will try to slim it down, however keep most of it since I am unsure at this point what could be cause.
The issue is, that the game works as expected. When it is time for the modal to render, it appears at the bottom left of the page, with no styling floating left. The functionality however works as expected, the buttons work and it displays the raw content.
import { Modal } from 'antd';
//rest of imports
const initialState = {
visible: false,
streak: 0,
score: 0,
turn: 0,
previousPicks: [],
result: { result: "", player: "", computer: "" }
};
class Game extends React.Component {
constructor(props) {
super(props);
this.turnLimit = 10;
this.state = initialState;
}
componentWillUnmount() {
this.setState(initialState)
}
updateScore = () => {
//handles score
}
updatePreviousPicks = () => {
//update game data
}
onClickHandler = async (choice) => {
//fetching data from backend
self.showModal();
}
getAIResult = () => {
//
}
showModal = () => {
if (this.state.turn === 10) {
this.setState({
visible: true,
});
}
}
handleOk = () => {
this.setState(initialState)
}
handleCancel = () => {
this.setState(initialState)
}
render() {
return (
<div>
<div>
<Modal
title="Basic Modal"
centered={true}
visible={this.state.visible}
onOk={this.handleOk}
onCancel={this.handleCancel}></Modal>
</div>
<div className="container">
<div id="rockDiv" className={`choice`} onClick={() => this.onClickHandler("rock")}>
<Choices choice="rock"></Choices>
</div>
<div id="paperDiv" className={`choice`} onClick={() => this.onClickHandler("paper")}>
<Choices choice="paper"></Choices>
</div>
<div id="scissorsDiv" className={`choice`} onClick={() => this.onClickHandler("scissors")}>

</div>
<Score score={this.state.score} bonus={this.state.streak} turn={this.state.turn} />
<div id="PlayerResult" className={this.state.result.result} >
{this.state.turn >= 1 ? <p>You</p> : <p></p>}
<Answer choice={`${this.state.result.player}`} />
</div>

I have tried removing all CSS from the component, and still the modal does not show with the default antd design?
As I understand that current style you have doesn't like example of Antd.
Missing is you didn't import styles of Antd like this.
import { Modal, Button } from "antd";
import "antd/dist/antd.css";
Just need import style you will have what you need.
You can check my example here https://codesandbox.io/embed/8lr93mw8yj
<Modal
title="Basic Modal"
centered="true"
visible={this.state.visible}
onOk={this.handleOk}
onCancel={this.handleCancel}></Modal>
You do not need to wrap the "true" in brackets here as you are not calling a variable.
I have a react component that has a state variable:
showEditor
when showEditor is false it is supposed to show only a div with some number inside it (initially showEditor is false). If this state variable is true my react component is supposed to show a textbox and a button with "save" label inside another div -making dissapear the first div with the number-. This textbox will be used to change the number. For the first div (the one that only shows a number) I defined:
<div onClick={this.showEditorProc}>
{ this.state.showEditor ?
<div ....>
{ just the numeric value }
</div>
:
<div ....>
textBox
<button onClick={save and make show Editor false}>
Save
</button>
</div>
</div>
the function this.showEditorProc will modify the state of the showEditor variable to true and the save button and textbox components will appear (inside another div too). I created a function that will executed if the save button is clicked. This function modifies the showEditor variable to false however, I can not see the div with just the numeric value. Instead I still see the textbox with the save button. Is there something else I could be missing? Here it is the code of my component:
import React from 'react';
import ReactDOM from 'react-dom';
import NumberFormat from 'react-number-format';
export class NumericBox extends React.Component {
constructor() {
super();
this.state = {
enteredValue: '',
showNumEditor: false,
index: ''
};
this.showNumericEditor = this.showNumericEditor.bind(this);
this.handle_enteredValue_change = this.handle_enteredValue_change.bind(this);
this.saveCellInfo = this.saveCellInfo.bind(this);
this.loadBasicInformation = this.loadBasicInformation.bind(this);
}
saveCellInfo(e){
alert(this.state.index);
/* cellAuxParams = new Map([['updateCellValue', this.state.updateCellValue]]); */
console.log('numericBox.js>saveCellInfo>cellAuxParams= ------------------------------------------------ ' + 28);
console.log(this.props.cellAuxParams);
var f = this.props.cellAuxParams.get('updateCellValue');
this.setState({showNumEditor: false}, () => f(this.state.Index, '77'));
}
handle_enteredValue_change(values) {
const {formattedValue, value} = values;
// formattedValue = $2,223
// value ie, 2223
this.setState({enteredValue: value});
}
showNumericEditor()
{
this.setState({showNumEditor: true})
}
loadBasicInformation()
{
this.setState({enteredValue: this.props.enteredValue,
index: this.props.index
});
}
componentDidMount(){
this.loadBasicInformation();
}
componentWillReceiveProps(nextProps){
alert(nextProps.enteredValue);
this.setState({enteredValue: nextProps.enteredValue}, () => this.loadBasicInformation());
}
render() {
const table4controls = {

</div>
<div style={table4controls_ColsStyleC}>

</div>
</div>
:
<div syle={table4controls_ColsStyleA}>
{this.state.enteredValue}
</div>
}
</div>
);
}
}
You have an onClick={this.showNumericEditor} handler on the surrounding div, so when you press the save button, the click event bubbles up and invokes a this.setState({showNumEditor: true}).
To fix it, you can either restructure the rendering or call e.stopPropagation(); at the start of saveCellInfo. Also note that some of your this.saveCellInfo calls are not passing the event.
I'm having a bit of a head ache trying to figure out the React way of implementing this.
I have a Searches component which houses SearchItems, when an item is clicked among other things I need to set it's state to active to that it gets the correct CSS, I managed to get this working fine but how would I go about removing the active state from the others?
I was thinking that I could pass down a function from the top level component that would take the ID of the search, when clicked it'd zip through SearchItems and change their state to either true/false depending on which ID it was?
Code below!
Top level component:
import React from "react";
import {Link} from "react-router";
import Search from "./Search";
export default class Searches extends React.Component {
constructor(){
super();
this.state = {
searches : [
{
id : "2178348216",
searchName: "searchName1",
matches: "5"
},
{
id : "10293840132",
searchName: "searchName2",
matches: "20"
}
]
};
}
render() {
const { searches } = this.state;
const SearchItems = searches.map((search) => {
return <Search key={search.id} {...search}/>
})
return (
<div> {SearchItems} </div>
);
}
}
Search items component
export default class Search extends React.Component {
constructor() {
super();
// Set the default panel style
this.state = {
panelStyle: { height: '90px', marginBottom: '6px', boxShadow: '' },
selected: false
}
}
isActive(){
return 'row panel panel-success ' + (this.state.selected ? 'active' : 'default');
}
viewNotifications(e){
this.setState({selected: true});
}
render() {
const { id, searchName, matches } = this.props;
const buttonStyle = {
height: '100%',
width: '93px',
backgroundColor: '#FFC600'
}
return (
<div style={this.state.panelStyle} className={this.isActive()}>
<div class="col-xs-10">
<div class="col-xs-7">
Search Name: {searchName}
</div>
<div class="col-xs-7">
Must Have: PHP, MySQL
</div>
<div class="col-xs-7">
Could Have: AngularJS
</div>
</div>
<button type="button" onClick={this.viewNotifications.bind(this)} style={buttonStyle} class="btn btn-default btn-lg"> {matches} </button>
</div>
);
}

I think you don't need the state in the child component at all. In fact is a good idea to avoid having state in most components so they are easy to reason and reuse.
I would leave all the state only on the parent component in this case.
TOP Component:
import React from "react";
import Search from "./search";
export default class Searches extends React.Component {
constructor(){
super();
this.state = {
searches : [
{
id : "2178348216",
searchName: "searchName1",
matches: "5"
},
{
id : "10293840132",
searchName: "searchName2",
matches: "20"
}
],
activeElement : null
};
}
_onSearchSelect(searchId) {
this.setState({'activeElement': searchId})
}
render() {
const { searches, activeSearchId } = this.state;
const SearchItems = searches.map((search) => {
return <Search key={search.id} {...search}
isActive={search.id === activeElement}
onSelect={this._onSearchSelect.bind(this)} />
})
return (
<div> {SearchItems} </div>
);
}
}
CHILD Component:
import React from "react";
export default class Search extends React.Component {
_getPanelClassNames() {
const { isActive } = this.props
return 'row panel panel-success ' + (isActive ? 'active' : 'default')
}
_onSelect() {
const { id, onSelect } = this.props;
onSelect(id)
}
render() {
const { searchName, matches } = this.props;
const panelStyle = { height: '90px', marginBottom: '6px', boxShadow: '' }
const buttonStyle = {
height: '100%',
width: '93px',
backgroundColor: '#FFC600'
}
return (
<div style={panelStyle} className={this._getPanelClassNames()}>
<div className="col-xs-4">
Search Name: {searchName}
</div>
<div className="col-xs-3">
Must Have: PHP, MySQL
</div>
<div className="col-xs-3">
Could Have: AngularJS
</div>
<div className="col-xs-2">
<button type="button" onClick={this._onSelect.bind(this)}
style={buttonStyle} className="btn btn-default btn-lg"
>
{matches}
</button>
</div>
</div>
);
}
}

Ok it turns out this is simpler than I thought and is simply a case of understanding how react works(and not getting confused) .
When you have a top level component you pass it's state via props to children, when you update the state in the top level component it'll pass that down to the children and you can use componentWillReceiveProps to take action.
I added a function to my top level component called updateActiveSearch which simply sets the state of the TOP level component I then passed the activeElement state as a prop to the child Elements along with the function. When a child element calls this function to set itself as active all of them will fire componentWillReceiveProps, they simply just need to check their own ID against the one they've received, if it matches they're active, if it doesn't they're not!
So my top level component now looks like this:
export default class Searches extends React.Component {
constructor(){
super();
this.state = {
searches : [
{
id : "2178348216",
searchName: "searchName1",
matches: "5"
},
{
id : "10293840132",
searchName: "searchName2",
matches: "20"
}
],
activeElement : 0
};
}
// This function gets passed via a prop below
updateActiveSearch(id){
//console.log(id);
this.setState({activeElement : id});
}
render() {
const SearchItems = this.state.searches.map((search) => {
return <Search activeElement={this.state.activeElement} goFunction={this.updateActiveSearch.bind(this)} key={search.id} {...search}/>
})
return (
<div> {SearchItems} </div>
);
}
}
CHILD COMPONENTS
export default class Search extends React.Component {
constructor() {
super();
// Set the default panel style
this.state = {
panelStyle: { height: '90px', marginBottom: '6px', boxShadow: '' },
selected: false
}
}
// This happens right before the props get updated!
componentWillReceiveProps(incomingProps){
if(incomingProps.activeElement == this.props.id){
this.setState({selected: true});
} else {
this.setState({selected: false});
}
}
isActive(){
return 'row panel panel-success ' + (this.state.selected ? 'active' : 'default');
}
viewNotifications(e){
//this.state.panelStyle.boxShadow = '-2px 3px 20px 5px rgba(255,198,0,1)';
this.setState({selected: true});
this.props.goFunction(this.props.id);
}
render() {
const { id, searchName, matches } = this.props;
const buttonStyle = {
height: '100%',
width: '93px',
backgroundColor: '#FFC600'
}
return (
<div style={this.state.panelStyle} className={this.isActive()}>
<div class="col-xs-10">
<div class="col-xs-7">
Search Name: {searchName}
</div>
<div class="col-xs-7">
Must Have: PHP, MySQL
</div>
<div class="col-xs-7">
Could Have: AngularJS
</div>
</div>
<button type="button" onClick={this.viewNotifications.bind(this)} style={buttonStyle} class="btn btn-default btn-lg"> {matches} </button>
</div>
);
}
}
