javascript - react-router 返回一个页面 你如何配置历史记录？

Question

谁能告诉我如何返回上一页而不是特定路径？

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记录

这是我的路线:

// 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);
 });

React v16 和 ReactRouter v4.2.0 更新(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>
    )
  }
}

React v15 和 ReactRouter v3.0.0 更新(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>
    );
  }
});

创建了一个带有嵌入式 iframe 的更复杂示例的 fiddle :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，你有必要的历史可以回去。如果您直接点击该页面然后返回，它会将您带回到您的应用程序之前的浏览器历史记录中。

此解决方案将处理这两种情况。但是，它不会处理可以使用后退按钮在页面内导航(并添加到浏览器历史记录)的 iframe。坦率地说，我认为这是 react-router 中的一个错误。此处创建的问题:https://github.com/rackt/react-router/issues/1874
