Pass props in Link react-router

Question

I am using react with react-router. I am trying to pass property’s in a "Link" of react-router

var React  = require('react');
var Router = require('react-router');
var CreateIdeaView = require('./components/createIdeaView.jsx');

var Link = Router.Link;
var Route = Router.Route;
var DefaultRoute = Router.DefaultRoute;
var RouteHandler = Router.RouteHandler;
var App = React.createClass({
  render : function(){
    return(
      <div>
        <Link to="ideas" params={{ testvalue: "hello" }}>Create Idea</Link>
        <RouteHandler/>
      </div>
    );
  }
});

var routes = (
  <Route name="app" path="/" handler={App}>
    <Route name="ideas" handler={CreateIdeaView} />
    <DefaultRoute handler={Home} />
  </Route>
);

Router.run(routes, function(Handler) {

  React.render(<Handler />, document.getElementById('main'))
});

The "Link" renders the page but does not pass the property to the new view. Below is the view code

var React = require('react');
var Router = require('react-router');

var CreateIdeaView = React.createClass({
  render : function(){
    console.log('props form link',this.props,this)//props not recived
  return(
      <div>
        <h1>Create Post: </h1>
        <input type='text' ref='newIdeaTitle' placeholder='title'></input>
        <input type='text' ref='newIdeaBody' placeholder='body'></input>
      </div>
    );
  }
});

module.exports = CreateIdeaView;

How can I pass data using "Link"?

Answer 1

there is a way you can pass more than one parameter. You can pass "to" as object instead of string.

// your route setup
<Route path="/category/:catId" component={Category} / >

// your link creation
const newTo = { 
  pathname: "/category/595212758daa6810cbba4104", 
  param1: "Par1" 
};
// link to the "location"
// see (https://reacttraining.com/react-router/web/api/location)
<Link to={newTo}> </Link>

// In your Category Component, you can access the data like this
this.props.match.params.catId // this is 595212758daa6810cbba4104 
this.props.location.param1 // this is Par1

Answer 2

I had the same problem to show an user detail from my application.

You can do this:

<Link to={'/ideas/'+this.props.testvalue }>Create Idea</Link>

or

<Link to="ideas/hello">Create Idea</Link>

and

<Route name="ideas/:value" handler={CreateIdeaView} />

to get this via this.props.match.params.value at your CreateIdeaView class.

You can see this video that helped me a lot: https://www.youtube.com/watch?v=ZBxMljq9GSE

Answer 3

See this post for reference

The simple is that:

<Link to={{
     pathname: `your/location`,
     state: {send anything from here}
}}

Now you want to access it:

this.props.location.state

Answer 4

as for react-router-dom 4.x.x (https://www.npmjs.com/package/react-router-dom) you can pass params to the component to route to via:

<Route path="/ideas/:value" component ={CreateIdeaView} />

linking via (considering testValue prop is passed to the corresponding component (e.g. the above App component) rendering the link)

<Link to={`/ideas/${ this.props.testValue }`}>Create Idea</Link>

passing props to your component constructor the value param will be available via

props.match.params.value

Answer 5

After install react-router-dom

<Link
    to={{
      pathname: "/product-detail",
      productdetailProps: {
       productdetail: "I M passed From Props"
      }
   }}>
    Click To Pass Props
</Link>

and other end where the route is redirected do this

componentDidMount() {
            console.log("product props is", this.props.location.productdetailProps);
          }

Answer 6

Typescript

For approach mentioned like this in many answers,

<Link
    to={{
        pathname: "/my-path",
        myProps: {
            hello: "Hello World"
        }
    }}>
    Press Me
</Link>

I was getting error,

Object literal may only specify known properties, and 'myProps' does not exist in type 'LocationDescriptorObject | ((location: Location) => LocationDescriptor)'

Then I checked in the official documentation they have provided state for the same purpose.

So it worked like this,

<Link
    to={{
        pathname: "/my-path",
        state: {
            hello: "Hello World"
        }
    }}>
    Press Me
</Link>

And in your next component you can get this value as following,

componentDidMount() {
    console.log("received "+this.props.location.state.hello);
}

To work off the answer above (https://stackoverflow.com/a/44860918/2011818), you can also send the objects inline the "To" inside the Link object.

<Route path="/foo/:fooId" component={foo} / >

<Link to={{pathname:/foo/newb, sampleParam: "Hello", sampleParam2: "World!" }}> CLICK HERE </Link>

this.props.match.params.fooId //newb
this.props.location.sampleParam //"Hello"
this.props.location.sampleParam2 //"World!"

For v5

 <Link
  to={{
    pathname: "/courses",
    search: "?sort=name",
    hash: "#the-hash",
    state: { fromDashboard: true }
  }}
/>

Answer 9

Inside your Link component do the state

<Link to='register' state={{name:'zayne'}}>

Now to access the item in the page you went to, import useLocation

import {useLocation} from 'react-router-dom';

const Register=()=>{

const location = useLocation()

//store the state in a variable if you want 
//location.state then the property or object you want

const Name = location.state.name

return(
  <div>
    hello my name is {Name}
  </div>
)

}

Answer 10

In my case I had a function component with empty props and this solved it:

<Link
  to={{
    pathname: `/dashboard/${device.device_id}`,
    state: { device },
  }}
>
  View Dashboard
</Link>

In your function component you should have something like this:

import { useLocation } from "react-router"
export default function Dashboard() {
  const location = useLocation()
  console.log(location.state)
  return <h1>{`Hello, I'm device ${location.state.device.device_id}!`}</h1>
}

Answer 11

The simplest approach would be to make use of the to:object within link as mentioned in documentation:
https://reactrouter.com/web/api/Link/to-object

<Link
  to={{
    pathname: "/courses",
    search: "?sort=name",
    hash: "#the-hash",
    state: { fromDashboard: true, id: 1 }
  }}
/>

We can retrieve above params (state) as below:

this.props.location.state // { fromDashboard: true ,id: 1 }

Answer 12

If you are just looking to replace the slugs in your routes, you can use generatePath that was introduced in react-router 4.3 (2018). As of today, it isn't included in the react-router-dom (web) documentation, but is in react-router (core). Issue#7679

// myRoutes.js
export const ROUTES = {
  userDetails: "/user/:id",
}


// MyRouter.jsx
import ROUTES from './routes'

<Route path={ROUTES.userDetails} ... />


// MyComponent.jsx
import { generatePath } from 'react-router-dom'
import ROUTES from './routes'

<Link to={generatePath(ROUTES.userDetails, { id: 1 })}>ClickyClick</Link>

It's the same concept that django.urls.reverse has had for a while.

Answer 13

I was struggling with this for a few hours and not a single answer in this topic worked for me. Finally I managed to find a solution for React Router 6 in the documentation.

Here is full example:

// App.js

<BrowserRouter>
    <Routes>
        <Route path="/books/:bookId" element={ <BookDetails /> } />
    </Routes>
</BrowserRouter>

// BookDetails.js

import React from "react"
import { useParams } from "react-router-dom"

export default function BookPage() {
    const params = useParams()
    return <div> { console.log(params.bookId) } </div>
}

Note that useParams cannot be called inside a class component so you must use function component (see this answer for details).

Answer 14

Route:

<Route state={this.state} exact path="/customers/:id" render={(props) => <PageCustomer {...props} state={this.state} />} />

And then can access params in your PageCustomer component like this: this.props.match.params.id.

For example an api call in PageCustomer component:

axios({
   method: 'get',
   url: '/api/customers/' + this.props.match.params.id,
   data: {},
   headers: {'X-Requested-With': 'XMLHttpRequest'}
 })

Updating 25-11-21 Thanks for alex-adestech.mx who wrote above. I was able to transfer the whole object and pull out all the necessary fields from it in send-component :

<Button type="submit" component={NavLink} to={{
        pathname: '/basequestion',
        state: {question} }}
        variant="contained"
        size="small">Take test</Button>

in receive-component:

import { useLocation } from "react-router"
const BaseQuestion = () => {
const location = useLocation();
const {description, title, images} = (location.state.question);

For v6:

// route setup
<Route path="/employee-edit/:empId" element={<EmployeeEdit />} / >

Link to Component

<Link to={"/employee-edit/1"} state={{ data: employee }} > Edit </Link>

or

<Link to={{
       pathname: "/employee-edit/1",
       search: "?sort=name",
       hash: "#the-hash",
     }}
       state={{ data: employee }} > Edit </Link>

Note: state is outside from to{}, but for v5:

<Link
  to={{
    pathname: "/courses",
    search: "?sort=name",
    hash: "#the-hash",
    state: { fromDashboard: true }
  }}
/>
          

Funtional component:

import React from "react";
import { useLocation } from "react-router-dom";

const LinkTest = () => {
  const location = useLocation();
  console.log("Location", location);
  return <h1>Link Test</h1>;
};

export default LinkTest;

Class Component: in order to work with hooks, we need to wrap it in functional component and pass props:

import React, { Component } from "react";
import { useLocation, useParams } from "react-router-dom";

class LinkTestComponent extends Component {
  render() {
    console.log(this.props);
    return <h1>Link Test</h1>;
  }
}

export default () => (
  <LinkTestComponent params={useParams()} location={useLocation()} />
);

Tested with: "react-router-dom": "^6.2.2",
