i'm trying to use react router in my reactjs app. And I encountered this problem:
This is what i'm trying to do:
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import About from '../Pages/About';
import Home from '../Pages/Home';
import Topics from '../Pages/Topics';
import LinkTest from '../Pages/LinkTest';
class AppRouter extends Component {
render() {
return (
<Router>
<div>
<ul>
<li>
<Link to="/home">Home</Link>
</li>
<li>
<Link to="/about">About</Link>
</li>
<li>
<Link to="/topics">Topics</Link>
</li>
<Route path="/home" component={LinkTest}/>
</ul>
<hr />
<Route path="/home" component={Home}/>
<Route path="/about" component={About} />
<Route path="/topics" component={Topics} />
</div>
</Router>
);
}
}
export default AppRouter;
Ignore "about" and "topic" component, when I click on "Home" link, it should target 2 routes, one will render "LinkTest" and the other renders "Home".
This is what inside "LinkTest":
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
class LinkTest extends Component {
render() {
const {match}=this.props;
return (
<div>
<Link to={`${match.url}/Test`}>Link To Test</Link>
</div>
);
}
}
export default LinkTest;
And inside my "Home" component:
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import Test from './Test';
class Home extends Component {
render() {
const {match} = this.props;
console.log(match.url);
return (
<Router>
<div>
<h2>
Hello from Home page
<Link to={`${match.url}/Test`}>Link To Test</Link>
<Route path={`${match.url}/Test`} component={Test}/>
</h2>
</div>
</Router>
);
}
}
export default Home;
However:
When i click on the link inside "LinkTest" component (which was rendered earlier), the url on the browser is shown " http://localhost:3000/home/Test ", but nothing happens.
When i clicked on the link inside "Home" component, (which was rendered the same time as the "LinkTest" using the same link), it showed the same url on the browser: " http://localhost:3000/home/Test ", only this time it rendered the "Test" component.
Why does this happen? (what i want to achieve is I want to use the link inside "LinkTest" to render "Test" component inside "Home" component, or something similar).
I hope this is clear enough.
You can do it in following way:
<Route exact path='/a' component={A} />
<Route path='/b' component={B} />
// Following should be router inside Component B
<Route exact path='/b/abc' component={OtherComponent}
If you want I've prepared few react-router 4 examples. These are hosted here. https://github.com/SandipNirmal/react-router-examples
If you need Nested routing inside ComponentB
you should add Link
s for those Route
s as well. And use match.url
and match.path
to build the nested Link
s and Route
s.
const ComponentB = ({ match }) => {
return (
<div>
<div>
<ul>
<li><Link to={`${match.url}/c`}>Component C</Link></li>
// more Links
<li><Link to={`${match.url}/css`}>CSS</Link></li>
<li><Link to={`${match.url}/react`}>React</Link></li>
</ul>
</div>
<div>
<Route path={`${match.path}/c`} component={ComponentC} />
// more nested Routes
<Route path={`${match.path}/css`} render={() => { return <h1>CSS</h1> }}/>
<Route path={`${match.path}/react`} render={() => { return <h1>React</h1> }}/>
</div>
</div>
);
}
Components created via Route will automatically be passed the following prop
objects: match
, location
and history
.
Using match
you can implement nested Route
s. The match
object contains the following properties:
params
— (object) Key/value pairs parsed from the URL corresponding to the dynamic segments of the path isExact
— (boolean) true if the entire URL was matched (no trailing characters) path
— (string) The path pattern used to match. Useful for building nested Route
surl
— (string) The matched portion of the URL. Useful for building nested Link
s
