react-router4@笔记

---

新项目使用react-router@4来进行路由跳转，使用非static的配置方式该用jsx。之前配置动态生成路由一直报错，发现提示route必须要有父级，在外面嵌套了div，才成功了，但是在官方文档中并未提及，也没看懂他的用意。

0、 页面入口

import React,{Component} from "react";
import reactDom from 'react-dom';
import "../css/index.less";
import SNCRouter from "./route"

class Index extends Component{
    componentWillReceiveProps(){

    }
   componentDidMount(){
      console.log("index")
   }
   render(){
       return 

           
       
   }
}
reactDom.render(,document.querySelector("#SNC-router"))

1、路由代码

import React, { Component } from "react";
import { HashRouter as Router, Route, Link, Switch } from 'react-router-dom';
import { send, store } from "../controller/reduxList.js";
import { routerIndex } from '../route/route-index';
const routers = [...routerIndex];
class SNCRouter extends Component {
    set404() {
        return 
404
    }
    setRoute() {
        return routers.map((r, i) => {
            return 
        })
    }
    render() {
        return 
            
                {
                    this.setRoute()
                }
                
            
        

    }
}

export default SNCRouter;
