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

最简单的方法是使用文档中提到的链接中的to:对象: https://reactrouter.com/web/api/Link/to-object

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

我们可以检索上面的params (state)如下:

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

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!"

安装react-router-dom后

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

和路由重定向的另一端这样做

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

在我的情况下，我有一个空道具的功能组件，这解决了它:

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

在你的函数组件中，你应该有这样的东西:

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>
}

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'}
 })
