react-router 4 路由的嵌套

1.在component組件內部須要嵌套的位置直接嵌套Route標籤

這個方法會使得路由標籤比較分散,子組件咱們必須直接將Route標籤寫入到父組件之中，並且路由必須包含根路徑.

// Dashboard.jsx 
import Menu from '~/components/Menu/Menu';
import React from 'react';
import {Route,Switch} from "react-router-dom";
import Index from '~/container/Index/Index';
import TaskList from '~/container/TaskManage/TaskList/TaskList'

const routes = [
    {
        path: "/Dashboard/Index",
        component: Index
    },
    {
        path: "/Dashboard/TaskManage/TaskList",
        component: TaskList
    }
];

class Dashboard extends React.Component{
    constructor(props, context ) {
        super(props, context );
    }

    render(){
        return(
            <div>
                <Menu/>
                <div className='container'>
                    <div>
                       {routes.map((route, index) => (
                            <Route
                                exact
                                key={index}
                                path={route.path}
                                component={route.component}
                            />
                        ))}
                    </div>
                </div>
            </div>
        )
    }
}
export default Dashboard

2.使用Route render渲染做內聯嵌套

component使用this.props.children進行嵌套渲染,Dashboard爲父組件,Index和TaskList爲子組件

// router.js
<Router history={history}>
                <Switch>
                    <Route exact path="/" component={Login}/>
                    <Route path="/" render={({history,location,match}) => (
                        <Dashboard history={history} location={location} match={location}>
                            <Route path="/Dashboard/Index" component={Index}></Route>
                            <Route path="/Dashboard/TaskManage/TaskManageIng" component={TaskManageIng}></Route>
                            <Route path="/Dashboard/TaskManage/TaskList" component={TaskList}></Route>
                            <Route path="/Dashboard/TaskManage/TaskResource" component={TaskResource}></Route>
                        </Dashboard>
                    )} />
                </Switch>
            </Router>
// Dashboard.jsx 
import Menu from '~/components/Menu/Menu';
import React from 'react';

class Dashboard extends React.Component{
    constructor(props, context ) {
        super(props, context );
    }

    render(){
        return(
            <div>
                <Menu/>
                <div className='container'>
                    <div>
                       {this.props.children}
                    </div>
                </div>
            </div>
        )
    }
}
export default Dashboard
