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

为了解决上面的问题(https://stackoverflow.com/a/44860918/2011818)，您还可以在Link对象的“To”中发送对象。

<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!"

其他回答

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'}
 })

我为此挣扎了几个小时，没有一个答案对我有用。最后，我设法在文档中找到了React Router 6的解决方案。

下面是完整的例子:

// 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>
}

注意，useParams不能在类组件中调用，因此必须使用函数组件(详细信息请参阅此回答)。

在Link组件中执行状态

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

现在要访问页面中的项目，导入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>
)

}

有一种方法可以传递多个参数。你可以传递"to"作为对象而不是字符串。

// 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

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;
