react-router基本用法

1. 說明：
   a. 引入模塊：
   
   b. 定義路徑和鏈接：
   
   c. 定義子路徑：
   
   d. 定義單擊跳轉事件：
   

2. 完整代碼：

   var React = require('react')
   var ReactDom = require('react-dom')
   var ReactRouter = require('react-router-dom')
   var Router = ReactRouter.BrowserRouter
   var Route = ReactRouter.Route
   var Link = ReactRouter.Link
   var browserHistory = ReactRouter.browserHistory
   var CreateClass = require('create-react-class')
   var PropTypes = require('prop-types')
   var Index = CreateClass({
   render:function(){
       return (
           <Router history={browserHistory}>
               <div>
                   <ul>
                       <li><Link to="/">Home</Link></li>
                       <li><Link to="/about">About</Link></li>
                       <li><Link to="/docs">Docs</Link></li>
                   </ul>
                   <hr/>
                   <Route exact path="/" component={Home}/>
                   <Route path="/about" component={About}/>
                   <Route path="/docs" component={Docs}/>
                   <Route path="/step1" component={Step1}/>
               </div>
           </Router>
       )
   }
   })
   var Home = CreateClass({
   render:function(){
       return(
           <div>
               <h2>Home</h2>
           </div>
       )
   }
   })
   var About = CreateClass({
   render:function(){
       return(
           <div>
               <h2>About</h2>
           </div>
       )
   }
   })
   var Docs = CreateClass({
   render:function(){
       return(
           <div>
               <ul>
                   <li><Link to="/step1">Step1</Link></li>
               </ul>
   
               <hr/>
   
               <Route exact path="/step1" component={Step1}/>
           </div>
       )
   }
   })
   var Step1 = CreateClass({
   onClick:function(){
       var history = this.props.history
       history.push('/')
   },
   render:function(){
       return(
           <div>
               <span onClick={this.onClick}>回到主頁</span>
               <h2>Step1</h2>
           </div>
       )
   }
   })
   ReactDom.render((
   <Index/>
   ), document.body)

3. 效果：
   a. 主頁：
   
   b. 父頁面：
   
   c. 子頁面：
   
   d. 點擊回到主頁：
   
4. 手動控制跳轉：
   a. 引入組件：

   var ReactRouter = require('react-router-dom')
   var withRouter = ReactRouter.withRouter

   
   b. 使用：

   this.props.history.push("/")

   
   c. 導出：

   module.exports = withRouter(Login)

5. 使用hash路由（使代碼打包後可以在本地運行）：
   a. 引入模塊：

   var Router = ReactRouter.HashRouter

   
   b. 使用：

   <Router>
   <LocaleProvider locale={Cn}>
       <div className="index_container">
           <Head/>
           <Route exact path="/" component={Home}/>
           <Route path="/home" component={Home}/>
           <Route path="/login" component={Login}/>
           <Route path="/system" component={System}/>
           <Route path="/user" component={User}/>
           <Foot/>
           <Write/>
       </div>
   </LocaleProvider>
   </Router>

6. 404頁面：
   a. 引入：

   var Switch = ReactRouter.Switch

   b. 定義：

   <Switch>
   <Route exact path="/some/path" component={XXX}/>
   <Route path="*" component={Notfound}/>
   </Switch>
