react-route-dom 实现简单的嵌套路由

最终效果
点击 to test1

点击to test2  =>  to test21

点击to test2  =>  to test22

代码如下
 

          path: "page",
          element: <父组件 />,
          children: [
            { path: "test1", element:  },
            {
              path: "test2",
              element: ,
              children: [
                { path: "test21", element:  },
                { path: "test22", element:  },
              ],
            },
          ],

父组件如下 

   import { NavLink, Outlet } from "react-router-dom";    

         

          I am 父组件
          

             to test1
          
          

             to test2
          
          

            
          
        

test1组件

import React from "react";
const Test1 = () => {
  return 
 I am test1
;
};
export default Test1;

test2组件

import React from "react";
import { NavLink, Outlet } from "react-router-dom";

const Test2 = () => {

         to test21
      
      

         to test22
      
      

        
      
    
  );
};
