本篇文章给大家带来的内容是关于vue.js中二级路由和三级路由的代码解析，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

为什么要用二级和三级路由？

当项目中有多个时，就必须使用分级路由；

如果路由不分级，又有多个 ,全部都是定义为一级路由，那么项目中的的内容显示就会混乱；这是不友好的；

如果对路由进行分级，那么当触发某个二级或三级路由时，此路由就会将对应组件内容传给自己的父级路由组件里面的，这样就不会混乱；

一级路由被触发时，自然会找自己所注册的根组件的

二级路由

为一级路由添加一个 children 属性数组，并将二级路由放入；

path 属性决定跳转后 url 地址栏的的显示

//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:[
        {path:&#39;/about/contsssssssssssssssact&#39;,name:&#39;contactLink&#39;,component:Contact},
        {path:&#39;/history&#39;,name:&#39;historyLink&#39;,component:History},
        {path:&#39;/&#39;,name:&#39;deliveryLink&#39;,component:Delivery},
        {path:&#39;/orderingGuide&#39;,name:&#39;orderingGuideLink&#39;,component:OrderingGuide},
      ]},
    {path:&#39;*&#39;,redirect:&#39;/&#39;}
  ],
  mode:"history"
});

三级路由

和二级路由差不多

const router= new VueRouter({
  routes:[
    {path:&#39;/&#39;,name:&#39;home&#39;,component:Home},
    {path:&#39;/menu&#39;,name:&#39;menu&#39;,component:Menu},
    {path:&#39;/admin&#39;,name:&#39;admin&#39;,component:Admin},
    {path:&#39;/about&#39;,name:&#39;about&#39;,component:About,redirect: {name:&#39;contactLink&#39;},children:[   //二级路由
        {path:&#39;/about/contact&#39;,name:&#39;contactLink&#39;,component:Contact},
        {path:&#39;/history&#39;,name:&#39;historyLink&#39;,component:History},
        {path:&#39;/delivery&#39;,name:&#39;deliveryLink&#39;,component:Delivery},
        {path:&#39;/orderingGuide&#39;,name:&#39;orderingGuideLink&#39;,component:OrderingGuide,redirect:{name:&#39;phonelink&#39;},children: [  //三级路由
            {path:&#39;/phone&#39;,name:&#39;phonelink&#39;,component:Phone},
            {path:&#39;/name&#39;,name:&#39;namelink&#39;,component:Name}
          ]},
      ]},
    {path:&#39;/login&#39;,name:&#39;login&#39;,component:Login},
    {path:&#39;/register&#39;,name:&#39;register&#39;,component:Register},
    {path:&#39;*&#39;,redirect:&#39;/&#39;}
  ],
  mode:"history"
});
