I am new at react and I can understand the difference between React.Component and a function.
In these two pictures I have the same HTML and the same CSS but my CSS is done in the javascript file. When I use the CSS in a function, it works, but in a react component it does not.
Component
render() {
const classes = useStyles();
return (
<div style={section}>
<div style={container}>
<div>
<div style={title}>
<h1>TEste</h1>
</div>
</div>
</div>
</div>
)
}
Function
const classes = useStyles();
return (
<div className={classes.section}>
<div className={classes.container}>
<div>
<div className={classes.title}>
<h1>1</h1>
</div>
</div>
</div>
</div>
);

I have an AppLayout component which has:
A div with the h-full utility class, to make it take the full page height.
A Background component to make a background with blur. It has three main elements:
Navbar
Outlet, which dynamically changes height
Footer
import { Outlet } from 'react-router-dom';
import Background from '../components/Background';
import Footer from '../components/Footer';
import NewNavbar from '../components/NewNavbar';
export const AppLayout = () => (
<div className='h-full'>
<Background>
<div className='min-h-full backdrop-blur-2xl flex flex-col'>
<div>
<NewNavbar />
</div>
<div className='flex-auto'>
<Outlet />
</div>
<div className=''>
<Footer />
</div>
</div>
</Background>
</div>
);
As you see, I applied flex flex-col to my "wrapper" div and flex-auto to a div wrapping my Outlet component, but this is not working. When I use straight HTML and CSS, the footer is placed correctly at the bottom of the page, and it always works.
All was so simple.
export const AppLayout = () => (
<div className='h-full'>
<Background >
<div className='min-h-screen backdrop-blur-2xl flex flex-col'>
<div>
<NewNavbar />
</div>
<div className='flex-auto'>
<Outlet />
</div>
<div>
<Footer />
</div>
</div>
</Background>
</div>
);
Replace the min-h-full to min-h-screen
I want to build a Carousel in Sitecore NextJs. I found a carousel package to do so, but it hardcodes the number of slides. Since the author will create the slides dynamically in Sitecore, my NextJs component should be smart enough to detect the number of "child slides" added to the Carousel and render them accordingly.
This is the example I found online:
import React, { Component } from 'react';
import "react-responsive-carousel/lib/styles/carousel.min.css";
import { Carousel } from 'react-responsive-carousel';
export default class NextJsCarousel extends Component {
render() {
return (
<div>
<h2>NextJs Carousel - GeeksforGeeks</h2>
<Carousel>
<div>
<img src="/1.png" alt="image1"/>
<p className="legend">Image 1</p>
</div>
<div>
<img src="/2.png" alt="image2" />
<p className="legend">Image 2</p>
</div>
<div>
<img src="/3.png" alt="image3"/>
<p className="legend">Image 3</p>
</div>
<div>
<img src="/4.png" alt="image4"/>
<p className="legend">Image 4</p>
</div>
<div>
<img src="/5.png" alt="image5"/>
<p className="legend">Image 5</p>
</div>
</Carousel>
</div>
);
}
};
Instead, I want the Slides within the Carousel to be dynamic and use a loop based on how many slides are added under my Carousel component in Sitecore.
I am using react-slick for my carousels you may follow something similar approach as i did for your react-responsive-carousel.
My Slider Component:
export const MainSlider: FC<SliderProps> = ({
settings,
data,
type,
className,
}) => {
if (!(data.length > 0)) return null;
return (
<Fragment>
<div className="mian-slider">
<div className="container cus-container">
<div className="main-sec-slider">
<div className="img-box-back" />
<SlickSlider {...settings} className={className}>
{data.map((value, index) => {
return (
<div key={index}>
{type === "main-carousel"
? InnerSlider.Main(value)
: InnerSlider.Article(value)}
</div>
);
})}
</SlickSlider>
</div>
</div>
</div>
</Fragment>
);
};
Inside map function you can pass another component as i did with name InnerSlider which contains html code for your carousel images.
In your case you need to pass this:
<div>
<img src="/1.png" alt="image1"/>
<p className="legend">Image 1</p>
</div>
at last pass props data for MainSlider component :
<MainSlider
settings={settings}
data={[YOUR_SLIDER_DATA_ARRAY]}
type="main-carousel"
className="slider-main-text"
/>
I am beginner in reactjs, I want to copy a color when I click on color.
How should it be done?
import React from 'react';
const Green = ()=>{
return (
<div>
<h1 className='g-color-title'>Green Color</h1>
<div className='container-fluid'>
<div className='div-style' id='color31'> #2ECC72 </div>
<div className='div-style' id='color32'> #26AE60 </div>
<div className='div-style' id='color33'> #6AB04A </div>
<div className='div-style' id='color34'> #43BE31 </div>
<div className='div-style' id='color35'> #10A881 </div>
<div className='div-style' id='color36'> #019031 </div>
<div className='div-style' id='color37'> #75DA8B </div>
<div className='div-style' id='color38'> #218F76 </div>
<div className='div-style' id='color39'> #218F76 </div>
<div className='div-style' id='color40'> #7CEC9F </div>
</div>
</div>
)
}
export default Green;
You can use navigator.clipboard.writeText() to copy text to the clipboard.
I would recommend using an object of colors, then with Object.entries() and map() create the <div>s and add an onClick() to trigger it:
const Green = () => {
const colors = {
color31: '#2ECC72',
color32: '#26AE60',
color33: '#6AB04A',
color34: '#43BE31',
color35: '#10A881',
color36: '#019031',
color37: '#75DA8B',
color38: '#218F76',
color39: '#218F76',
color40: '#7CEC9F',
};
return (
<div>
<h1 className='g-color-title'>Green Color</h1>
<div className='container-fluid'>
{Object.entries(colors).map(([id, color]) =>
<div className='div-style' id={id} onClick={navigator.clipboard.writeText(color)}>{color}</div>
)}
</div>
</div>
);
}
export default Green;
I started creating a blog like react application and using bootstrap grid system.
There seems to be a big space between my two columns. Is there a way to get rid of this?
A screen shot is attached.
import React from 'react';
import ReactDom from 'react-dom';
import 'bootstrap/dist/css/bootstrap.css';
import faker from 'faker';
//Now create a new component
const App = () => {
const myCustomStyle = {color:'green', fontSize:'50px'}
return (
<div className="container">
<div className="row">
<div class="col-3">
<img alt="avatar" src={faker.image.avatar()}></img>
</div>
<div class="col-9" >
<p><b>Alex</b><span>Today at 5.00pm</span></p>
<p>Great blog post!</p>
</div>
</div>
</div>
)
}
ReactDom.render(<App />, document.querySelector('#root'))
Use the Bootstrap 4 auto layout columns instead...
col-auto - flex shrink
col - flex grow
<div class="container">
<div class="row">
<div class="col-auto">
<img alt="avatar" src="//placehold.it/100" />
</div>
<div class="col">
<p><b>Alex</b><span>Today at 5.00pm</span></p>
<p>Great blog post!</p>
</div>
</div>
</div>

I am trying to successfully express Semantic-UI code with the same functions I have used in Semantic-UI-react code. Any help would be appreciated.
This is what I have:
class Preview extends React.Component {
componentDidMount() {
const update = () => {
this.dest.textContent = this.src.innerHTML.replace(/</g,
'\n<');
};
setInterval(update, 300);
update();
}
render() {
return (
<div>
<div ref={(src) => Object.assign(this, { src })}>
<Demo />
</div>
<pre ref={(dest) => Object.assign(this, { dest })}>
</pre>
</div>
)
}
}
export class Demo extends Component { constructor(){
super();
this.localStorageClear.bind(this); }
localStorageClear = (e) => {
e.preventDefault();
window.localStorage.clear();
};
render() {
return (
<div id = "soundcloud-player">
<Container className='col'>
<div className='col-left js-playlist toggle'>
<div className='inner'>
</div>
</div>
<div className='col-right'>
<div className = 'main'>
<Input size='massive' icon='search' input = {{ className:
'input-search js-search' }} placeholder='Search for a song
or artist...'/>
<Icon className='js-submit'/>
<Button onClick={(e) => this.localStorageClear(e)}
className='clear' content='Clear Playlist'/>
<Button content='Show/Hide Playlist' id='toggle'
className='hide-toggle'/>
<Card className='js-search-results search-results'/>
</div>
</div>
</Container>
</div>
The code written in the Preview Component is specifically written to convert the code written inside of the Demo Component. The Demo Component should convert to what is shown below:
<div class="ui container col">
<div class="col-left js-playlist toggle">
<div class="inner">
</div>
</div>
<div class="col-right">
<div class="main">
<div class="ui massive icon input">
<input placeholder="Search for a song or artist..." class="js-search input-search">
<i class="search icon js-submit"></i>
</div>
<button onclick="localStorageClear();" class="clear">Clear Playlist</button>
<button class="hide-toggle" href="#" id="toggle">Show/Hide Playlist</button>
<div class="search-results js-search-results ui cards">
</div>
</div>
</div>
The actual output of the code at the top is:
<div id="soundcloud-player">
<div class="ui container col">
<div class="col-left js-playlist toggle">
<div class="inner">
</div>
</div>
<div class="col-right">
<div class="main">
<div class="ui massive icon input input-search">
<input placeholder="Search for a song or artist..." type="text">
<i aria-hidden="true" class="search icon">
</i>
</div>
<i aria-hidden="true" class="icon js-submit">
</i>
<button class="ui button clear" role="button">Clear Playlist
</button>
<button id="toggle" class="ui button hide-toggle" role="button">Show/Hide Playlist
</button>
<div class="ui card js-search-results search-results">
</div>
</div>
</div>
</div>
</div>
I'm trying to figure out why the localStorageClear function does not show up for the first button in the actual output. Is there wrong I am doing at the top inside of the Semantic-UI-React code inside of the Demo Component?
The way you are setting up your handler function is not correct. You are also binding in your constructor AND inline with an arrow function inside of the onClick event for the button. You only need to bind in one place.
Take a look at the codesandbox example I made so you can see how to declare a class method handler function and use it with a click event. Notice that there is no constructor here or arrow function to bind on the onClick event? That is because the binding is happening on the class method. handleClick = () => {}
class App extends React.Component {
handleClick = e => {
console.log(e.target + " was clicked.");
// Do whatever functionality you need here.
// In your example you do not show that it matters what the element is,
// so you don't need to pass the event (e) into your class method.
};
render() {
return (
<Container>
<Divider hidden />
<Button content="Click Me" onClick={this.handleClick} />
<Divider hidden clearing />
<Message info>
Look in your console and you will see that the click function is
working.
</Message>
</Container>
);
}
}
Here is a working codesandbox example.
