On a project I just started on reactjs, I should hide an element when the url changes. I searched and did not find something useful.
I would like to hide the Sidebar when the url is not Search. Thanks to anyone who wants to give me a hand.
import React from 'react';
import { Routes, Route } from "react-router-dom";
import 'bootstrap/dist/css/bootstrap.css';
import 'react-bootstrap';
import './App.css';
import NavBarTop from './components/layouts/header/NavBar_top';
import Sidebar from './components/layouts/Sidebar';
import Home from './components/pages/Home';
import Login from './components/pages/Login';
import Register from './components/pages/Register';
import Search from './components/pages/Search';
import E404 from './components/pages/E404';
function App() {
return (
<>
<div>
<NavBarTop />
<div className="container-fluid maincon">
<Sidebar />
<Routes>
<Route path="/" exact element={<Home />} />
<Route path="/login" element={<Login />} />
<Route path="/register" element={<Register />} />
<Route path="/search" element={<Search />} />
<Route path="*" element={<E404 />} />
</Routes>
</div>
</div>
</>
);
}
export default App;
I would like to hide the Sidebar when the url is not Search.
Just render the Sidebar only with the Search component instead of unconditionally with everything.
<div>
<NavBarTop />
<div className="container-fluid maincon">
<Routes>
<Route path="/" element={<Home />} />
<Route path="/login" element={<Login />} />
<Route path="/register" element={<Register />} />
<Route
path="/search"
element={(
<>
<Sidebar />
<Search />
</>
)}
/>
<Route path="*" element={<E404 />} />
</Routes>
</div>
</div>
If you wanted to render Sidebar with several routes, then create a layout component. Nested/wrapped Route components are rendered into the Outlet component.
import { Outlet } from 'react-router-dom';
const SidebarLayout = () => (
<>
<Sidebar />
<Outlet />
</>
);
...
<div>
<NavBarTop />
<div className="container-fluid maincon">
<Routes>
<Route path="/" element={<Home />} />
<Route path="/login" element={<Login />} />
<Route path="/register" element={<Register />} />
<Route element={SidebarLayout}>
<Route path="/search" element={<Search />} />
... other routes to render with sidebar ...
</Route>
<Route path="*" element={<E404 />} />
</Routes>
</div>
</div>
there are multiple ways to do that.. this is only one...
export default function Wrapper() {
const urlWindow = window.location;
console.log(urlWindow.pathname.split("/")[1]);
const acceptedPaths = ["login", "register", "search", "test"];
return (
<>
<div>
navbar
<div className="container-fluid">
<div className="row">
{acceptedPaths.includes(urlWindow.pathname.split("/")[1]) ? (
<>
<Sidebar />
<MainContent />
</>
) : "Show 404 page"}
</div>
</div>
</div>
</>
);
}
const Sidebar = () => {
return <div className="col-md-2">I'm sidebar</div>;
};
const MainContent = () => {
return <div className="col-md-10">I'm main content</div>;
};
Firstly, you need import useLocation in react-router-dom
import { Routes, Route, useLocation } from "react-router-dom";
and call it in App function to get the current URL path which is used to check against /search for hiding/showing SideBar
function App() {
const location = useLocation();
const currentPath = location.pathname
return (
<>
<div>
<NavBarTop />
<div className="container-fluid maincon">
{currentPath === '/search' && <Sidebar />}
<Routes>
<Route path="/" exact element={<Home />} />
<Route path="/login" element={<Login />} />
<Route path="/register" element={<Register />} />
<Route path="/search" element={<Search />} />
<Route path="*" element={<E404 />} />
</Routes>
</div>
</div>
</>
);
}
