前情提要：最近在学习react，然后就将项目中遇到的bug总结下来，作为借鉴！
项目结构：

|app.js
|main.js
|center.js
|toutiao.js
|quanzi.js
|shipin.js

html文件：
<!DOCTYPEhtml> <htmllang="en"> <head> <Metacharset="UTF-8"> <Metaname="viewport"content="width=device-width,initial-scale=1.0"> <Metahttp-equiv="X-UA-Compatible"content="ie=edge"> <title>Document</title> </head> <body> <divid="Box"> </div> <scriptsrc="http://localhost:8080/webpack-dev-server.js"></script> <scriptsrc="app.js"></script> <scriptsrc="main.js"></script> </body> </html>
app.js、main.js、center.js、toutiao.js、quanzi.js、shipin.js、dinggou.js文件如下：
//app.js文件 importReactfrom'react'; import{Link}from'react-router'; importJqueryfrom"./jquery.js"; importstylesfrom"./style.css"; classAppextendsReact.Component{ constructor(props){ super(props); } render(){ return( <div> <h1>欢迎访问主界面</h1> <divclassName="showBox"> { this.props.children } </div> <ul> <li><Linkto="/center"activeStyle={{background:"blue"}}>用户中心</Link></li> <li><Linkto="/quanzi"className="danger">圈子</Link></li> <li><Linkto="/shipin"activeStyle={{background:"blue"}}>视频</Link></li> <li><Linkto="/toutiao"activeStyle={{background:"blue"}}>头条</Link></li> <li><Linkto="/dinggou"activeStyle={{background:"blue"}}>订购</Link></li> </ul> </div> ); } } //代替A标签不需要使用hash值 //this.props.children指代是每一个route嵌套结构下的子组件 exportdefaultApp
//main.js文件 importReact,{Component,PropTypes}from'react'; importReactDOM,{render}from'react-dom'; import{Router,Route,hashHistory,Link,browserHistory,IndexRoute,IndexRedirect,Redirect}from'react-router'; importAppfrom'./app.js'; importCenterfrom'./center.js'; importToutiaofrom'./toutiao.js'; importQuanzifrom'./quanzi.js'; importDinggoufrom'./dinggou.js'; importShipinfrom'./shipin.js'; importstylesfrom"./style.css" //1.主视图 vardoc=document.getElementById("Box"); render(( <Routerhistory={browserHistory}> <Routepath="/"component={App}> <IndexRoutepath="/center"component={Center}/>//设置默认路由 <Routepath="/toutiao"component={Toutiao}/> <Routepath="/quanzi"component={Quanzi}/> <Routepath="/shipin"component={Shipin}/> <Routepath="/dinggou"component={Dinggou}/> <IndexRedirectto="/toutiao"></IndexRedirect> </Route> </Router> ),doc)
