Change back to previous state onClick button and texts - reactjs

How do I change the text and button text back to its original state with an onClick? I know theres a setTimeout but I only want the change to revert back FOR BOTH the button and text when I click on it. Currently I can only use it one way. If i click on it, it changes from Original to new but I will like to change back to Original if i click on it again. Thanks!
Code:
import React, {useState} from 'react'
const Card = () => {
const[text, setText] =useState('original')
const [buttonText, setButtonText] = useState("Original");
return (
<div className='translate uppercase py-5 break-normal text-center mx-4 space-y-2 font-bold'>
<div className="App">
<button className='rounded-full border-black border-solid'
type="submit"
onClick={() => {
setButtonText("New");
setText('New')
}}
>
{buttonText}
</button>
</div>
<h2>{text}</h2>
</div>
)
}
export default Card;

If you Know both values you can use this solution
import React, {useState} from 'react'
const Card = () => {
const [captions, setCaptions] = useState([
{ buttonText: "orginal", text: "orginal" },
{ buttonText: "new", text: "new" }
]);
const[flag, setFlag] =useState(0)
return (
<div className='translate uppercase py-5 break-normal text-center mx-4 space-y-2 font-bold'>
<div className="App">
<button className='rounded-full border-black border-solid'
type="submit"
onClick={() => {
setCaptions(captions);
setFlag(flag === 0 ? 1 : 0);
}}
>
{captions[flag].buttonText}
</button>
</div>
<h2>{captions[flag].text}</h2>
</div>
)
}
export default Card;
If you don't know new value you can add to captions new value

Try this:
const [isOriginal, setIsOriginal] = useState(true)
onClick={() => {
if(isOriginal) {
setButtonText("New");
setText('New')
setIsOriginal(false)
} else if (!isOriginal) {
setButtonText("Original");
setText('original')
setIsOriginal(true)
}
}
By checking the original state, you can conditionally set text values.

SlateJS React trying to get a textfield to work inside an Element

I have a Slate element that looks like this:
import React, {useState} from 'react'
import "./App.css"
export default function Accordion(props) {
const [closed, setClosed] = useState(false) //todo eventually fetch starting position from savefile
const [heightClass, setHeightClass] = useState("")
const handleToggle = () => {
if(closed === false){
setHeightClass("h-0")
}
else{
setHeightClass("")
}
setClosed(!closed)
}
return (
<>
<div {...props.attributes}>
{/* title and button */}
<div className='flex justify-between '>
<div className='font-semibold'>
<DefaultElement {...props}/> //the title of the accordion
</div>
<div
className={`px-2 cursor-pointer font-bold font-mono select-none ${closed ? "rotate-180" : ""}`}
onClick={() => {
handleToggle()
}}>
V
</div>
</div>
{/* ${closed ? "h-0" : ""} */}
<div className={`rounded border-l px-2 overflow-hidden accordionTransition `}
style={{height: closed ? "0px" : ""}}>
{props.children}
</div>
</div>
</>
)
}
const DefaultElement = props => {
console.log(props)
return <p {...props.attributes}>
{props.children}
</p>
}
Which is used by the Editor in App.js:
const App = () => {
const [editor] = useState(() => withReact(createEditor()))
// Define a rendering function based on the element passed to `props`. We use
// `useCallback` here to memoize the function for subsequent renders.
const renderElement = useCallback(props => {
switch (props.element.type) {
case 'accordion':
return <Accordion {...props} />
default:
return <DefaultElement {...props} />
}
}, [])
return (
<div className='p-5'>
<Slate editor={editor} value={initialValue}>
<Editable
// Pass in the `renderElement` function.
renderElement={renderElement}
/>
</Slate>
</div>
)
}
const DefaultElement = props => {
return <span {...props.attributes}>
{props.children}
</span>
}
export default App;
I'm trying to get the Accordion title to be properly editable and work as Slate intended. Just a a simple textfield. I can't figure out the correct syntax and how i'm supposed to do this.
When i do this, the title and the accordion content (props.children) are the same. I don't understand why.
If i remove the <DefaultElement {...props}/> and just write some text, it throws me this error when i edit it: Uncaught Error: Cannot resolve a Slate point from DOM point: [object Text],4

Button onClick opens all image preview instead one

I'm trying to figure out how to open one item(at my situation image gallery), but not all at once.
I'm using FsLightbox dependencies. My code seems working until I'm triggering button to open the image gallery, but it opens all three columns.
index.js
import React, { useState } from 'react';
import Menu from './Menu';
import Button from './Button';
import data from './Data';
import './style.css';
const allCategories = ['Visi', ...new Set(data.map(item => item.category))];
const Projects = () => {
const [menuItem, setMenuItem] = useState(data);
const [buttons, SetButtons] = useState(allCategories);
// console.log(data);
const filter = (button) => {
if(button === 'Visi'){
setMenuItem(data);
return;
}
const filteredData = data.filter(item => item.category === button);
setMenuItem(filteredData);
}
return (
<div id="projects" className="App">
<div className="title">
Projektai
</div>
<Button button={buttons} filter={filter}/>
<Menu menuItem={menuItem}/>
</div>
)
}
export default Projects
all my data and images in data.js file
import skardis1 from '../../images/projects/1.jpg'
import skardis2 from '../../images/projects/2.jpg'
import skardis3 from '../../images/projects/3.jpg'
const data = [
{
id:1,
image: skardis1,
title: 'PAVADINIMAS',
category: 'Privatūs',
description: 'ČIA KAŽKOKS TEKSAS',
projectimages: [skardis2, skardis3]
},
{
id:2,
image: skardis2,
title: 'PAVADINIMAS',
category: 'Visuomeniniai',
description: 'ČIA KAŽKOKS TEKSAS',
projectimages: [ skardis3, skardis2 ]
},
{
id:3,
image: skardis3,
title: 'PAVADINIMAS',
category: 'Visuomeniniai',
description: 'ČIA KAŽKOKS TEKSAS',
projectimages: [ skardis3, skardis2 ]
},
];
export default data;
and the main Menu.js file
import React, { useState } from 'react';
import FsLightbox from 'fslightbox-react';
import {Animated} from "react-animated-css";
function Menu({menuItem}) {
const [toggler, setToggler] = useState(false);
return (
<div className="item">
{
menuItem.map((item) => {
return <div className="item-con" key={item.id}>
<Animated animationIn="fadeIn" animationOut="fadeOut" animationInDuration={1800} animationOutDuration={2400} isVisible={true}>
<div className="item-container">
<img src={item.image} alt=""/>
<h2>{item.title}</h2>
<p>{item.description}</p>
<button onClick={() => setToggler(!toggler)}> Daugiau</button>
</div>
</Animated>
</div>
})
}
{
menuItem.map((item) => {
return <div>
<FsLightbox
toggler={toggler}
sources={item.projectimages}
/>
</div>})
}
</div>
)
}
export default Menu;
As I said it, then I clicked the button, it opens all three items. I want to click on the button to one item section; it opens only that item images in preview.. now I have to close the image preview three times. added IMG how my items columns look now
This is because all the FsLightbox has a shared toggler state.
To solve this, you could create a MenuItem component to render each item, each with it's own toggler state. For example:
function Menu({ menuItems }) {
return (
<div className="items">
{menuItems.map(item => <MenuItem item={item} />)}
</div>
);
}
function Menuitem({ item }) {
const [toggler, setToggler] = useState(false);
return (
<div className="item">
<div className="item-con" key={item.id}>
<Animated animationIn="fadeIn" animationOut="fadeOut" animationInDuration={1800} animationOutDuration={2400} isVisible={true}>
<div className="item-container">
<img src={item.image} alt="" />
<h2>{item.title}</h2>
<p>{item.description}</p>
<button onClick={() => setToggler(!toggler)}> Daugiau</button>
</div>
</Animated>
</div>
<div>
<FsLightbox toggler={toggler} sources={menuItem.projectimages} />
</div>
</div>
);
}
Now that each MenuItem has it's own local state, they should open individually based on the button you clicked.

Toggle specific div (id) within a react component

I have a site built with post-components to show articles in a feed. Inside the component, I have a button that opens a modal onClick. I use useState to toggle on the modal which works perfectly fine. The problem is that since the toggle is put on the modal-div inside the component.. every single post modal opens whenever I click one of the buttons. I want to open only the targeted post modal (with the sam post id as the button I’m clicking). I can’t figure out how to do this…in react.
const [toggle, setToggle] = useState (true);
const toggler = () => {
setToggle(prev => !prev)
}
...
return (
<section className="posts">
{data.allMarkdownRemark.edges.map((edge) => {
return (
<div className="post">
<div className="postDescrip">

like this.
use a object instead of a single boolean.
const [toggles, setToggles] = useState ({});
const createToggler = (id) = () => {
setToggle(prev => { [id]: !prev[id] }) // atmost one id is true. others is undefine or false.
// setToggle(prev => { ...prev, [id]: !prev[id] }) // or support multi modal at same time. but I think you don't want it.
}
...
return (

const id = ... // get your id form edge.
const toggle = toggles[id];
const toggler = createToggler(id);

React.js - Disable background scroll when a modal is showing

I am trying to disable the background body scroll when a modal pop up window is open. I created the Modal using React portal. The only way I can think of doing this is by giving the body an overflow-y property when the Modal is open, but am unsure how to execute this..
my Modal.js looks like this
export default function Modal({open, onClose, image, title, description}){
if (!open) return null
return ReactDom.createPortal(
<>
<div id="overlay" />
<div id="modal" >
<button title={title} onClick={onClose}>close</button>
<h3>{title}</h3>
<img src={image} className="modal-img"/>
{description}
</div>
</>,
document.getElementById('portal')
)
}
and the component where I am 'rendering' the model
const ProjectCardUI = (props)=>{
const[isOpen, setIsOpen] = useState(false)
function openModal() {
setIsOpen(true)
// can I set the styling for '.body' or 'html' here?
}
return(
<div className="card text-center container-fluid d-flex">
<a className="modal-click" onClick ={openModal}>this is a link</a>
<Modal
open={isOpen}
onClose={() => setIsOpen(false)}
title={props.cardName}
image={props.imgsrc}
description={props.cardDescription}>
</Modal>
</div>
)
};
any help would be great.
You can directly manipulate the body style via the document object.
For example:
import React from "react";
import ReactDOM from "react-dom";
export default function Test() {
const setHidden = () => {
console.log(document.body.style.overflow);
if (document.body.style.overflow !== "hidden") {
document.body.style.overflow = "hidden";
} else {
document.body.style.overflow = "scroll";
}
};
return (
<div>
<button onClick={setHidden}>Click me! </button>
<h1>1</h1>
<h1>2</h1>
<h1>3</h1>
<h1>4</h1>
<h1>5</h1>
<h1>6</h1>
<h1>7</h1>
<h1>8</h1>
<h1>9</h1>
<h1>10</h1>
<h1>11</h1>
<h1>12</h1>
<h1>13</h1>
<h1>14</h1>
<h1>15</h1>
<h1>16</h1>
</div>
);
}
ReactDOM.render(<Test />, document.getElementById("container"));
Maybe something like this:
const ProjectCardUI = (props) => {
const [isOpen, setIsOpen] = useState(false);
function openModal() {
setIsOpen(true);
// can I set the styling for '.body' or 'html' here?
}
useEffect(() => {
const body = document.querySelector('body');
body.style.overflow = isOpen ? 'hidden' : 'auto';
}, [isOpen])
return (
<div className="card text-center container-fluid d-flex">
<a className="modal-click" onClick={openModal}>
this is a link
</a>
<Modal
open={isOpen}
onClose={() => setIsOpen(false)}
title={props.cardName}
image={props.imgsrc}
description={props.cardDescription}
></Modal>
</div>
);
};

I have array of objects mapping to which showed multiple card on-page/feed. each card has a dropdown that the user can perform several actions for the clicked card. think of FB feed or any other social media feed card that the user can click to open a dropdown and pick option for the card. I am trying to achieve something similar but the problem is when I click on the button to open the dropdown it toggles all the dropdowns for all the cards instead of opening the dropdown for the clicked card.
Expected Behavior: open the dropdown for the clicked card only.
Change the open to take the id:
const [open, setOpen] = useState() // undefined is nothing open
const toggle = id => setOpen(open === id ? undefined : id) // close if currently open
// the JSX
return(
<div>
{textQuote.map((quote) => (
<div className="QuoteCardPrimaryContainer" key={quote.quoteId}>
<div>{quote.userName}</div>
<div className="ddContainer">
<span className="QuoteCardEngagementActionButtonIconContainer">
<span className="QuoteCardEngagementActionButtonIcon"
onClick={() => toggle(quote.quoteId)}>
options
</span>
</span>
{open === quote.quoteId && <QuoteCardDropdown targetLink={quote.quoteId}/>}
</div>
</div>
))}
</div>
)
Yes, you are trying to control all dropdowns using a single state variable open.
{open && <QuoteCardDropdown targetLink={quote.quoteId}/>}
When you click on any dropdown it will toggles open and then all dropdowns will open because that single variable controls all of them.
Instead, what you can do is maintain a separate state variable for each dropdown.
I have an example to maintain separate state variable for dropdown-
toggle = (index) => {
this.setState(prevState => {
[`open+${index}`]: !prevState[`open${index}`]
}
}
This way you can keep track of/or toggles open for particular dropdown you just need to change below code -
{
textQuote.map((quote, index) => ( //add 2nd parameter as index
<div className="QuoteCardPrimaryContainer" key={quote.quoteId}>
<div>{quote.userName}</div>
<div className="ddContainer">
<span className="QuoteCardEngagementActionButtonIconContainer">
<span className="QuoteCardEngagementActionButtonIcon"
onClick={() => this.toggle(index)}
>
options
</span>
</span>
{ this.state[`open${index}`] && <QuoteCardDropdown targetLink={quote.quoteId}/>}
</div>
</div>
</div>
))
}
Note - Unfortunately I am not aware of handling state as dynamically inside the function component, but I have given you the exact same use case using class component.
Use an object indexed by quote ID to track a card's open status by the quote ID. I copied only the relevant code, make sure this has all of the other code you need:
export const TextQuoteCard = () => {
const [openById, setOpenById] = useState({});
const toggle = (quoteId) => {
setOpenById((currOpenById) => {
const nextOpenById = { ...currOpenById };
if (currOpenById[quoteId]) {
delete nextOpenById;
} else {
nextOpenById[quoteId] = true;
}
return nextOpenById
})
}
// ...removed code not relevant to example
return (
<div>
{textQuote.map((quote) => (
<div className="QuoteCardPrimaryContainer" key={quote.quoteId}>
<div>{quote.userName}</div>
<div className="ddContainer">
<span className="QuoteCardEngagementActionButtonIconContainer">
<span
className="QuoteCardEngagementActionButtonIcon"
onClick={() => toggle(quote.quoteId)}
>
options
</span>
</span>
{openById[quote.quoteId] && <QuoteCardDropdown targetLink={quote.quoteId} />}
</div>
</div>
))}
</div>
);
};
