问题描述

我正在尝试更改点击页面。
这是点击功能

I am trying to change the page on click. Here is the click function

import React, { Component } from 'react';
import {BrowserRouter as Router,Route} from 'react-router-dom';
import { browserHistory } from 'react-router';
class Buttons extends Component {
skipClick(){
    browserHistory.push('/sessionstate2');
}
render() {
return (<a className={skipShow} onClick={this.skipClick}>Skip</a>)
}
}

和index.js

import browserHistory from 'react-router';
ReactDOM.render(
    <Router history={browserHistory}>
    <div>
      <Route exact path="/" component={App} />
      <Route exact path="/sessionstate1" component={Template1}/>
      <Route exact path="/sessionstate2" component={Template2}/>
      <Route exact path="/sessionstate3" component={Template3}/>
</div>
  </Router>,
   document.getElementById('root')
 );

给予

Uncaught TypeError：无法读取未定义的属性'push'

Uncaught TypeError: Cannot read property 'push' of undefined

你能告诉我这里我做错了什么吗？

Can you please tell me what am I doing wrong here?

推荐答案

这是一个可重现的例子，说明如何以编程方式更改路由器v4中的路由。

Here's a reproducible example of how to programmatically change routes in react router v4.

首先，为一个简单的应用程序安装样板：

First, install the boilerplate for a simple app:

sudo npm install -g create-react-app
create-react-app demo-app
cd demo-app
npm install react-router-dom

然后我们将 /src/App.js 更改为：

import React from 'react'
import {BrowserRouter as Router, Route, Link, withRouter} from 'react-router-dom'

const BasicExample = () => (
  <Router>
    <div>
      <li><Link to="/">Home</Link></li>
      <li><Link to="/about">About</Link></li>

      <Route exact path="/" component={Home}/>
      <Route path="/about" component={About}/>
    </div>
  </Router>
)

const Home = () => (
  <div>
    <h2>Home</h2>
  </div>
)

const Button = withRouter(({history}) => (
  <button type='button' onClick={() => { history.push('/new-location') }}>Click Me!</button>
))

const About = () => (
  <div>
    <h2>About</h2>
    <Button />
  </div>
)

export default BasicExample

然后启动服务器：

npm run start

如果你导航到localhost：3000，然后单击关于，您将看到按钮组件。单击它将以编程方式将路径更改为 / new-location

If you navigate to localhost:3000, then click About, you'll see the button component. Clicking it will programmatically change the route to /new-location
