在Link react-router中传递道具

我正在使用react和react-router。我试图在反应路由器的“链接”中传递属性

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'))
});

“Link”呈现页面，但不将属性传递给新视图。下面是视图代码

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;

如何使用“链接”传递数据?

当前回答

路线:

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

然后可以像这样访问PageCustomer组件中的参数:

例如，PageCustomer组件中的api调用:

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

其他回答

至于react-router-dom 4.x。X (https://www.npmjs.com/package/react-router-dom)你可以传递参数给组件路由到via:

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

通过(考虑testValue道具被传递给相应的组件(例如上面的App组件)来呈现链接)

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

将道具传递给组件构造函数，值参数将通过

props.match.params.value

对v5

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

在react-router v6中，它是state和useLocation:

<Link to={`/foo`} state={{title: 'foo'}}>

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

const FooPage = () => {
    const location = useLocation()

    return <>
        <h1>{location.state.title}</h1>
    </>
}
export default FooPage;

更新25-11-21 感谢alexadestech。Mx在上面写道。我能够转移整个对象，并从中抽出所有必要的字段在send-component中:

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

在receive-component:

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

如果你只是想替换路由中的蛞蝓，你可以使用react-router 4.3(2018)中引入的generatePath。到目前为止，它还没有包含在react-router-dom (web)文档中，但在react-router (core)中。问题# 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>

这和django.urls.reverse一段时间以来的概念是一样的。
