有没有人能告诉我如何回到上一页,而不是具体的路线?

当使用此代码时:

var BackButton = React.createClass({

 mixins: [Router.Navigation],
  render: function() {
    return (
        <button
            className="button icon-left"
            onClick={this.navigateBack}>
            Back
        </button>
    );
  },

  navigateBack: function(){
    this.goBack();
  }
});

得到这个错误,goBack()被忽略,因为没有路由器历史

以下是我的路线:

// Routing Components
Route = Router.Route;
RouteHandler = Router.RouteHandler;
DefaultRoute = Router.DefaultRoute;

var routes = (
 <Route name="app" path="/" handler={OurSchoolsApp}>
     <DefaultRoute name="home" handler={HomePage} />
     <Route name="add-school" handler={AddSchoolPage}  />
     <Route name="calendar" handler={CalendarPage}  />
     <Route name="calendar-detail" path="calendar-detail/:id" handler={CalendarDetailPage} />
     <Route name="info-detail" path="info-detail/:id" handler={InfoDetailPage} />
     <Route name="info" handler={InfoPage} />
     <Route name="news" handler={NewsListPage} />
     <Route name="news-detail" path="news-detail/:id" handler={NewsDetailPage} />
     <Route name="contacts" handler={ContactPage} />
     <Route name="contact-detail" handler={ContactDetailPage} />
     <Route name="settings" handler={SettingsPage} />
 </Route>
 );

 Router.run(routes, function(Handler){
   var mountNode = document.getElementById('app');
   React.render(<Handler /> , mountNode);
 });

返回指定页面:

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

  const history = useHistory();
  
  const routeChange = () => {
    let path = '/login';
    history.push(path);
  };

返回上一页:

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

  const history = useHistory();
  
  const routeChange = () => {
    history.goBack()
  };

更新React v16和ReactRouter v4.2.0(2017年10月):

class BackButton extends Component {
  static contextTypes = {
    router: () => true, // replace with PropTypes.object if you use them
  }

  render() {
    return (
      <button
        className="button icon-left"
        onClick={this.context.router.history.goBack}>
          Back
      </button>
    )
  }
}

更新React v15和ReactRouter v3.0.0(2016年8月):

var browserHistory = ReactRouter.browserHistory;

var BackButton = React.createClass({
  render: function() {
    return (
      <button
        className="button icon-left"
        onClick={browserHistory.goBack}>
        Back
      </button>
    );
  }
});

创建了一个稍微复杂一点的嵌入iframe的例子:https://jsfiddle.net/kwg1da3a/

React v14和ReacRouter v1.0.0(2015年9月10日)

你可以这样做:

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

var SomePage = React.createClass({
  ...

  contextTypes: {
    router: React.PropTypes.func
  },
  ...

  handleClose: function () {
    if (Router.History.length > 1) {
      // this will take you back if there is history
      Router.History.back();
    } else {
      // this will take you to the parent route if there is no history,
      // but unfortunately also add it as a new route
      var currentRoutes = this.context.router.getCurrentRoutes();
      var routeName = currentRoutes[currentRoutes.length - 2].name;
      this.context.router.transitionTo(routeName);
    }
  },
  ...

你需要小心,你有必要的历史回溯。如果你直接点击页面,然后再点击返回,它会带你回到应用之前的浏览器历史。

这个解决方案可以兼顾这两种情况。但是,它不会处理可以在页面中导航(并添加到浏览器历史记录中)的iframe(使用后退按钮)。坦白地说,我认为这是反应路由器的一个bug。问题创建在这里:https://github.com/rackt/react-router/issues/1874

如果你正在使用react-router v6,当你想要返回到前一页时,你可以使用Link:

第一步:你需要从react-router-dom中导入Link

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

第二步:像这样用Link包裹按钮。它工作得很完美。

<Link to='..'>
  <Button type='button'>Go Back</Button>
</Link>
import { withRouter } from 'react-router-dom'

this.props.history.goBack();

我正在使用这些版本

"react": "^15.6.1",
"react-dom": "^15.6.1",
"react-router": "^4.2.0",
"react-router-dom": "^4.2.2",

React路由器v6

useNavigate Hook是现在返回的推荐方式:

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

function App() {
  const navigate = useNavigate();

  return (
    <>
      <button onClick={() => navigate(-1)}>go back</button>
      <button onClick={() => navigate(1)}>go forward</button>
    </>
  );
}

Codesandbox样本

Go back/forward multiple history stack entries:
<button onClick={() => navigate(-2)}>go two back</button>
<button onClick={() => navigate(2)}>go two forward</button>
Go to specific route:
navigate("users") // go to users route, like history.push
navigate("users", { replace: true }) // go to users route, like history.replace
navigate("users", { state }) // go to users route, pass some state in

usenavate取代了useHistory以更好地支持即将到来的React悬疑/并发模式。

在react-router v4中。X你可以使用历史。goBack等价于history.go(-1)。

App.js

import React from "react";
import { render } from "react-dom";
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import Home from "./Home";
import About from "./About";
import Contact from "./Contact";
import Back from "./Back";

const styles = {
  fontFamily: "sans-serif",
  textAlign: "left"
};

const App = () => (
  <div style={styles}>
    <Router>
      <div>
        <ul>
          <li><Link to="/">Home</Link></li>
          <li><Link to="/about">About</Link></li>
          <li><Link to="/contact">Contact</Link></li>
        </ul>

        <hr />

        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route path="/contact" component={Contact} />

        <Back />{/* <----- This is component that will render Back button */}
      </div>
    </Router>
  </div>
);

render(<App />, document.getElementById("root"));

Back.js

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

const Back = ({ history }) => (
  <button onClick={history.goBack}>Back to previous page</button>
);

export default withRouter(Back);

请记住,通过使用历史记录,用户可以离开,因为history. goback()可以加载访问者在打开应用程序之前访问过的页面。


为了防止出现如上所述的情况,我创建了一个简单的react-router-last-location库来监视用户的最后位置。

用法非常简单。 首先你需要从npm安装react-router-dom和react-router-last-location。

npm install react-router-dom react-router-last-location --save

然后使用LastLocationProvider如下所示:

App.js

import React from "react";
import { render } from "react-dom";
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import { LastLocationProvider } from "react-router-last-location";
//              ↑
//              |
//              |
//
//       Import provider
//
import Home from "./Home";
import About from "./About";
import Contact from "./Contact";
import Back from "./Back";

const styles = {
  fontFamily: "sans-serif",
  textAlign: "left"
};

const App = () => (
  <div style={styles}>
    <h5>Click on About to see your last location</h5>
    <Router>
      <LastLocationProvider>{/* <---- Put provider inside <Router> */}
        <div>
          <ul>
            <li><Link to="/">Home</Link></li>
            <li><Link to="/about">About</Link></li>
            <li><Link to="/contact">Contact</Link></li>
          </ul>

          <hr />

          <Route exact path="/" component={Home} />
          <Route path="/about" component={About} />
          <Route path="/contact" component={Contact} />

          <Back />
        </div>
      </LastLocationProvider>
    </Router>
  </div>
);

render(<App />, document.getElementById("root"));

Back.js

import React from "react";
import { Link } from "react-router-dom";
import { withLastLocation } from "react-router-last-location";
//              ↑
//              |
//              |
//
//    `withLastLocation` higher order component
//    will pass `lastLocation` to your component               
//
//                   |
//                   |
//                   ↓
const Back = ({ lastLocation }) => (
  lastLocation && <Link to={lastLocation || '/'}>Back to previous page</Link>
);


//          Remember to wrap
//   your component before exporting
//
//                   |
//                   |
//                   ↓
export default withLastLocation(Back);
