I am new to React. I have the following components in the index.js React DOM area
ReactDOM.render(
<React.StrictMode>
<NavigationBar />
<App />
<Login />
</React.StrictMode>,
document.getElementById('root')
);
The NavigationBar was created using Bootstrap and when I click on the search button, I wanted the component to be removed and replaced by the component.
How do I do it?
you need to use useState :
when you clicked on button you need to change the state with onChange
const [check, setCheck] = useState(false);
ReactDOM.render(
<React.StrictMode>
<NavigationBar />
{check ? <App /> : anotherCoponent you want}
<Login />
</React.StrictMode>,
document.getElementById('root')
);

I am building a Netflix clone application, and I am using react-router-dom v5 to switch between different pages. However, when I click the Link tag in Navbar.jsx, the URL changes, but the corresponding component doesn't render.

There's a compatibility issue between pre-5.3.3 versions of react-router-dom#5 and react#18.
Github Issue #7870
PR #8831 merged to address issue - Fix was merged on May 18th, 2022, react-router-dom v5.3.3.
Solutions
Bugfix was merged into v5.3.3. Update to react-router-dom#5.3.3 or higher.
From the project's root directory run:
npm uninstall -S react-router-dom
npm install -S react-router-dom#5.3.3 (or #latest)
Revert back to React 17 (or React 17 syntax) and fix up the index.js file.
import { StrictMode } from "react";
import ReactDOM from "react-dom";
import App from "./App";
ReactDOM.render(
<StrictMode>
<App />
</StrictMode>,
document.getElementById("root")
);
Make the React.StrictMode component a child/descendent of the router component. Comment.
Replace:
<React.StrictMode>
...
<BrowserRouter>
...
</BrowserRouter>
</React.StrictMode>
with:
<BrowserRouter>
<React.StrictMode>
...
</React.StrictMode>
</BrowserRouter>
Upgrade to react-router-dom#6 and fix up the routes.
const App = () => {

<Router>
<Routes>

)
}
CPU.jsx(The component tobe rendered when user clicks on cpu category
function Info(){
render(
<h1>Hello in cpus </h1>
)
return null
}
The problem is when I Navigate on cpu it shows the same Home page but with the cpu component rendered in it..But the path is changed to "http://localhost:3000/cpu"
This is because in your index.js you are including <Home /> and then <App />.
For not showing Home you should include it into App as another route.
Eg.:
index.js
ReactDOM.render(
<div>
<App />
</div>,
document.getElementById('root')
)
App:
function App() {
return(
<Router>
<Switch>
<Route path="/cpu" exact component={Info}/>
<Route path="/" exact component={Home}/>
</Switch>
</Router>
)
}
your program is working correctly. Your ReactDOM.render always renders Home and App. But App is empty in root directory. If you click on the route /cpu the Info Component will shown inside the App component. Home remains unaffected.
I would take Home out of ReactDOM.render and assign a route in the App Component for it. but don't forget to assign exact path for the Home route, otherwise you still have the same result ;-)
This will help you:
https://reactrouter.com/web/guides/quick-start
I have a component build in ReactmyComponent.js
ReactDOM.render(
<MyComponent />,
document.getElementById('my-id')
);
In my Html, I want to render it twice, the HTML is as following:
<div id='my-id></div>
some html
<div id='my-id></div>
I want react render twice in this page, but it only render once for the second div. Is there anyway to render it twice?
You can't have the same id for two or more elements in HTML. Use different ids
<div id='my-id-one></div>
some html
<div id='my-id-two></div>
and call the ReactDOM.render separately for each id.
ReactDOM.render(
<MyComponent />,
document.getElementById('my-id-one')
);
ReactDOM.render(
<MyComponent />,
document.getElementById('my-id-two')
);
It looks like you want to render it in 2 different places, with non-React code in between. To do that, you'll want to give your divs different IDs:
<div id='my-id></div>
some html
<div id='my-other-id></div>
Then render the component to each div:
ReactDOM.render(
<MyComponent />,
document.getElementById('my-id')
);
ReactDOM.render(
<MyComponent />,
document.getElementById('my-other-id')
);
You could do
ReactDOM.render(
<div>
<MyComponent />
<MyComponent />
</div>, document.getElementById('my-id') );
Or You could also have two div tags with different id
<div id='one'></div>
some html
<div id='two'></div>
then
ReactDOM.render(
<MyComponent />,
document.getElementById('one')
);
ReactDOM.render(
<MyComponent />,
document.getElementById('two')
);
Another option is to use a class to define elements to render in:
<div id="my-id-one" class="render-here"></div>
some html
<div id="my-id-two" class="render-here"></div>
Then in js:
let elements = document.getElementsByClassName('render-here');
elements.map(element => ReactDOM.render(
<MyComponent />,
element
));
