• React实现局部刷新


    【项目结构】

    流程: 入口文件 -> 路由 -> layout -> Analysi/Monitor/Workspace

    1.入口文件 -> src/index.js

    2.组件 -> src/coms

    3.布局 -> src/layout

    4.路由 -> src/routes

    【流程解析】

    流程: 入口文件 -> 路由 -> layout -> Analysi/Monitor/Workspace

    1.路由部分

    //import React from 'react'; 引入类
    //import { Component } from 'react';  引入对象
    import React, { Component } from 'react';
    import {HashRouter, Route, Switch} from 'react-router-dom';
    
    //引入布局和子组件
    import BasicLayout from '../layout/layout';
    import Analysis from '../coms/Analysis';
    import Monitor from '../coms/Monitor';
    import Workplace from '../coms/Workplace';
    
    //分配路由
    const BasicRoute = () => (
        <HashRouter>
            <Switch>
                <Route exact path="/" component={BasicLayout}/>
                <Route exact path="/Analysis" component={Analysis}/>
                <Route  path="/Monitor" component={Monitor}/>
                <Route  path="/Workplace" component={Workplace}/>
            </Switch>
        </HashRouter>
    );
    
    export default BasicRoute;

    2.布局部分(重点

    import React, { Component } from 'react';
    import  {Layout ,Menu,Icon} from 'antd';
    import { Router, Route, Link,HashRouter } from 'react-router-dom'
    import 'antd/dist/antd.min.css'
    import BasicRoute from '../routes/router';
    
    const { Header, Footer, Sider, Content } = Layout;
    
    export default class BasicLayout extends Component {
      render() {
        return (
            <Layout>
            <Sider width={256} style={{ minHeight: '100vh', color: 'white' }}>
                
                <Menu theme="dark" mode="inline" >
                    {/*定义了项目的link,会按照路由走*/}
                    <Menu.Item><Link to="/Analysis">Item1</Link></Menu.Item>
                </Menu>
                
            </Sider>
            <Layout >
              <Header style={{ background: '#fff', textAlign: 'center', padding: 0 }}>Header</Header>
              <Content style={{ margin: '24px 16px 0' }}>
                <div style={{ padding: 24, background: '#fff', minHeight: 360 }}>
                  {/*Analysis.js文件引用了BasicLayout,并把自己的全部子节点(子组件)传过来*/}
                  {this.props.children}
                  
                </div>
              </Content>
              <Footer style={{ textAlign: 'center' }}>Ant Design ©2018 Created by Ant UED</Footer>
            </Layout>
          </Layout>
        )
      }
    }

    3.子组件(Analysis.js) (出错点

    import React from 'react';
    import BasicLayout from '../layout/layout';
    export default () => {
        //用BasicLayout标签包裹,内容传到layout.js的this.props.children部分
           return (<BasicLayout><h1>Analysis Page</h1></BasicLayout>)
    }

    【效果】

    【总结】

    按照antd官网的教程走了一遍,发现不能局部刷新

    原因在于官网用了umi框架。我是自己配置,有很多遗漏,导致子组件没有正确的传递到layout中。
