javascript - React 路由器向下滚动新页面

Question

我在使用 react-router ^2.4.1 时遇到了一个问题，如果我在我的主页上向下滚动然后转到一个新页面，它也会向下滚动，而不是在顶部(预期行为)。

我正在使用这个入门包:react-webpack-node我的 routes.jsx 看起来像这样

import React from 'react'
import { Route, IndexRoute } from 'react-router'
import cookie from 'react-cookie'

import App from 'containers/App'
import HomePage from 'containers/HomePage'
import WaitingListPage from 'containers/WaitingListPage'
import NotFoundPage from 'containers/NotFoundPage'
import SupportPage from 'containers/SupportPage'

/*
 * @param {Redux Store}
 * We require store as an argument here because we wish to get
 * state from the store after it has been authenticated.
 */
export default (store) => {
  const hasQueueToken = (nextState, replace, callback) => {
    if (cookie.load('queueToken')) {
      replace({
        pathname: `/waiting-list/${cookie.load('queueToken')}`,
        state: { nextPathname: nextState.location.pathname }
      })
    }
    callback()
  }

  return (
    <Route path='/' component={App}>
      <IndexRoute component={HomePage} />
      <Route path='/w_ref/:ref' component={HomePage} />
      <Route path='/waiting-list/:token' component={WaitingListPage} />
      <Route path='/waiting-list' onEnter={hasQueueToken} component={WaitingListPage} />
      <Route path='/support' component={SupportPage} />
      <Route path='/terms-and-conditions' component={TermsConditions} />
      <Route path='/privacy-policy' component={PrivacyPolicy} />
      <Route path='*' component={NotFoundPage} />
    </Route>
  )
}

React Router 从 2.0.0 版本开始不包括滚动状态管理。

推荐的方法是使用 react-router-scroll 用 scroll-behavior 装饰路由器，如 in this example 所示:

import { applyRouterMiddleware, browserHistory, Router } from 'react-router';
import useScroll from 'react-router-scroll';

/* ... */

ReactDOM.render(
  <Router
    history={browserHistory}
    routes={routes}
    render={applyRouterMiddleware(useScroll())}
  />,
  container
);
