我是React的新手我一直试图在单独的文件中声明路由,然后在索引文件中使用它。 这是我的routes.js。
import React from 'react';
import ReactDOM from 'react-dom';
import {
BrowserRouter as Router,
Route
} from 'react-router-dom';
import App from './components/App';
import Template1 from './components/template1';
import Template2 from './components/template2';
import Template3 from './components/template3';
const routes = (
<Route exact path="/" component={App}>
<Route exact path="/sessionstate1" component={Template1}/>
<Route exact path="/sessionstate2" component={Template2}/>
<Route exact path="/sessionstate3" component={Template3}/>
</Route>
)
export default routes
和index.js
import React from 'react';
import ReactDOM from 'react-dom';
import {
BrowserRouter as Router,
Route,Redirect
} from 'react-router-dom';
import './styles/css/index.css';
import routes from './routes.js';
ReactDOM.render(
<Router history={browserHistory} routes={routes} />,
document.getElementById('root')
);
我没有收到任何错误或警告,但页面未加载。请告诉我我错过了什么 感谢

我认为问题在于将Route
包裹在div
内。
尝试将它们包裹在Route
内,如下所示。试试这个fiddle并将路由包装器更改为div。
const routes=(
<Route >
<Route exact path="/sessionstate1" component={Template1}/>
<Route exact path="/sessionstate2" component={Template2}/>
<Route exact path="/sessionstate3" component={Template3}/>
</Route >
)
export default routes;
并将其导入index.js
import routes from './routes.js';
ReactDOM.render(
<Router history={browserHistory} routes={routes} />,
document.getElementById('root')
);

您不需要将路径包裹在div中。尝试这样的事情:
routes.js
<?php
$query= $conn->query("SELECT * FROM schedule where day = Monday and stud_id = 8888") or die(mysql_error());
$time = strtotime(date('h:iA'));
$result = $query->fetchAll();
foreach($result as $row) {
$timein = $row['timein'];
$timeout = strtotime($row['timeout']);
if ($time > $timeout)
{
continue;
}
else
{
echo $timein;
}
}
index.js
import React from 'react';
import { Router, Route } from 'react-router';
import { Template1, Template2, Template3 } from './templates';
const createRoutes = () => (
<Router>
<Route exact path="/sessionstate1" component={Template1}/>
<Route exact path="/sessionstate2" component={Template2}/>
<Route exact path="/sessionstate3" component={Template3}/>
</Router>
);
export default createRoutes;

index.js:
import LoginRoutes from './login/routes'
let routeConfig = [];
routeConfig = routeConfig.concat(LoginRoutes(store));
<Router routes={routeConfig}/>
routes.js:
export default (store) => {
return [
{path: '/login', component: Login},
{path: '/signup', component: SignUp},
]
}
通过这种方式,您可以添加来自不同文件的路线,并将路线定义分散到不同的文件夹中,以满足路线的上下文目的。
如果您想使用redux并希望在路由上拥有onEnter事件,那么存储变量就在那里。例如:
export default () => {
const sessionEnter = (location) => {
let {appId} = location.params;
store.dispatch(loadApp(appId));
return [
{path: '/apps/:appId', component: App, onEnter: sessionEnter},
]
}
我发现onEnter事件是componentDidMount的一个很好的替代方法,数据提取方式。在路由级别调用数据获取对我来说更有意义,因为我将组件视为表示级别的一部分。

带有打字稿
将用于路由的文件分隔为route.ts
export const routes = [
{ path: '/', component: Home },
{ path: '/auth-callback', component: authCallback },
{ path: '/fetch-data/:startDateIndex?', component: FetchData }
];
在App.tsx中
export function App() {
const routeComponents = routes.map(({ path, component }, key) => <Route exact path={path} component={component} key={key} />);
return (
<Layout>
{routeComponents}
</Layout>
);
}
Layout.tsx
export default (props: { children?: React.ReactNode }) => (
<React.Fragment>
<div>
<NavMenu />
<TopAppBarFixedAdjust>
{props.children}
</TopAppBarFixedAdjust>
</div>
</React.Fragment>
);

好几天前,我遇到了同样的问题,对我来说,解决方案是...
此路由文件之一:
import React from 'react';
import { Route } from 'react-router-dom';
import { ComponentY } from '../components/functionalitys';
export default [
<Route path="/appointment" component={ComponentY} exact key="create" />,
];
这是另一个路由文件:
import React from 'react';
import { Route } from 'react-router-dom';
import { LoginPage, Register } from '../components/user';
export default [
<Route path="/register" component={Register} exact key="create" />,
<Route path="/login" component={LoginPage} exact strict key="login" />
];
这就是我导入主app.js的方式:
import routesFromFile1 from './the/route';
import routesFromFile2 from './the/other/route';
class App extends Component{
render(){
return(
<div className="wrapper">
<section className="content container-fluid">
<Switch>
<Route exact path="/" component={Home} strict={true} exact={true}/>
<Route path="/500" component={InternalServer} />
{routesFromFile1}
{routesFromFile2}
</Switch>
</section>
</div>
)
}
}
希望对您有所帮助!干杯!

像这样试试
import React from "react";
import {HashRouter as Router, Route} from 'react-router-dom';
import NoteContainer from "./component/note/index.jsx";
import Header from "./component/common/header.jsx";
const App = (props) => {
return (
<div className="container">
<Header/> {props.children}
</div>
);
};
var x = () => {
return (
<h1>Hello world!</h1>
);
};
module.exports = () => {
return (
<Router>
<App>
<Route path="/" component={NoteContainer}/>
<Route path="/inbox" component={x}/>
</App>
</Router>
);
};

我知道我来晚了一点,但是我在这里工作 这里工作的demo
我的依赖项是
"react": "16.2.0", "react-dom": "16.2.0", "react-router-dom": "4.2.2", "react-scripts": "1.1.0"
以此创建nav.js文件 该文件负责存储导航栏的所有链接
import React, { Component } from "react";
import { Link } from "react-router-dom";
class Navi extends Component {
render = () => (
<div>
<Link to="/">Go to Home</Link> <br />
<Link to="/about">Go to About</Link> <br />
<Link to="/any-route">404 page</Link>
</div>
);
}
export default Navi;
然后是route.js文件 在这里,您将定义所有路线,以及路线应导航到的页面
import React, { Component } from "react";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
// your components
const Home = () => <h1>Home</h1>;
const About = () => <h1>About</h1>;
const MissingPage = () => <h1>404</h1>;
const routes = (
<Switch>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
<Route component={MissingPage} />
</Switch>
);
export default routes;
最后这是index.js的代码
import React, { Component } from "react";
import ReactDOM from "react-dom";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
import Navi from "./nav";
import routes from "./routes";
// initialize rotues and navi links
const initRoutes = () => (
<Router>
<div>
<Navi />
{routes}
</div>
</Router>
);
const initializedRoutes = initRoutes();
ReactDOM.render(
initializedRoutes,
document.getElementById("root")
);

也是新的反应并遇到了同样的问题。这是我尝试过的(显然不同的代码和结构,但我们正在寻找的应该是相同的功能)
index.js
import React from "react";
import ReactDOM from "react-dom";
import { createHashHistory } from "history";
import { BrowserRouter, Route } from 'react-router-dom';
import routes from "./routes";
const allRoutes = routes;
ReactDOM.render(
allRoutes,
document.getElementById("app")
)
和routes.js文件。
import React from "react";
import { createHashHistory } from "history";
import { BrowserRouter, Route } from 'react-router-dom';
import App from "./pages/App";
import Detail from "./pages/Detail";
import List from "./pages/List";
const routes = (
<BrowserRouter>
<div>
<Route exact path="/" component={ App } />
<Route path="/" component={ List } />
<Route path="/detail/:repo" component={ Detail } />
</div>
</BrowserRouter>
);
export default routes;
请告诉我这是否适合您。
