IT技术 - react - 路由器 withRouter 不注入路由器 - 吾爱随笔录

我想在名为“App”的顶级 React 组件上使用 withRouter。

文档在这里：https : //github.com/reactjs/react-router/blob/v2.4.0/upgrade-guides/v2.4.0.md#withrouter-hoc-higher-order-component

我像这样使用它：

import React from "react";
import { render } from "react-dom";
import {Router, Link, hashHistory, Route, IndexRoute, withRouter} from "react-router";
import VoteView from "./voteview/Voteview.jsx";
import OverView from "./overview/Overview.jsx";
import AppBar from 'material-ui/AppBar';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import injectTapEventPlugin from 'react-tap-event-plugin';

//Needed for onTouchTap
//Can go away when react 1.0 release
//Check this repo:
//https://github.com/zilverline/react-tap-event-plugin
injectTapEventPlugin();

const App = React.createClass({
  render() {
      return (
          <div>
              <AppBar
                title="Democratizer"
                onTitleTouchTap={()=>this.props.router.push('/')}
              >
              </AppBar>
              <br/>

            {this.props.children}
          </div>
      );
  }
});

render((
  <MuiThemeProvider muiTheme={getMuiTheme()}>
    <Router history={hashHistory}>
      <Route path="/" component={App}>
          <Route path="voteview/:baselineId" component={VoteView}/>
          <IndexRoute component={OverView}/>
      </Route>
    </Router>
  </MuiThemeProvider>
  ), document.getElementById('app'));

module.exports = withRouter(App);

我想使用 withRouter(App) 以使 Appbar Title 可点击。如果用户单击它，则应打开默认的“/”路径。这就是我试图通过onTitleTouchTap={()=>this.props.router.push('/')}.

我的问题是路由器不在那里。当用户点击 Appbar 中的标题时，会触发一个错误：Uncaught TypeError: Cannot read property 'push' of undefined。

withRouter(SomeComponent) 对我来说适用于组件树更下方的组件。但是在这种情况下我无法让它运行。

任何想法我做错了什么？
