Why use secondary and tertiary routing?

When there are multiple in the project, hierarchical routing must be used;

If the routing is not hierarchical and there are multiple , all of them are is defined as a first-level route, then the content display of in the project will be confusing; this is unfriendly;

If the route is hierarchical, then when a certain second-level or In the third-level routing, this route will pass the corresponding component content to the in its parent routing component, so that there will be no confusion;

When the first-level routing is triggered, naturally You will find the

secondary route of the root component you registered

Add a children attribute array to the first-level route and put the second-level route;

The path attribute determines the display of the url address bar after the jump

//main.js
//一级路由
import About from &#39;./components/about/About&#39;


//二级路由
import Contact from &#39;./components/about/Contact&#39;
import Delivery from &#39;./components/about/Delivery&#39;
import History from &#39;./components/about/History&#39;
import OrderingGuide from &#39;./components/about/OrderingGuide&#39;

const router= new VueRouter({
  routes:[
    {path:&#39;/about&#39;,name:&#39;about&#39;,component:About,children:[
