router

 

 

 这是vue-cli 4.0 以上创建项目默认的路由配置

// router/index.js

import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";

Vue.use(VueRouter);

const routes = [
  {
    path: "/",
    name: "Home",
    component: Home
  },
  {
    path: "/about",
    name: "About",
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () =>
      import(/* webpackChunkName: "about" */ "../views/About.vue")
  }
];

const router = new VueRouter({
  routes
});

export default router;

 简单二级路由

目录结构：

// Home.vue
<template>
  <div class="home">
    <div id="nav">
      <router-link to="/One">去第一个页面</router-link>
      <br>
      <router-link to="/Two">去第二个页面</router-link>
    </div>
  </div>
</template>

<script>
export default {
  name: "Home",
};
</script>

// One.vue
<template>
  <div>
    <div>这是第一个页面</div>
    <br>
    <button @click="Cilck">{{show ? '显示子组件':'关闭子组件'}}</button>
    <router-view></router-view>
  </div>
</template>

<script>
export default {
  data () {
    return {
      show: true
    }
  },
  methods: {
    Cilck () {
      this.show = !this.show
      this.show ? this.$router.push('/One') : this.$router.push('/One/oneSon')
      
    }
  }
}
</script>

<style>

</style>

// oneSon.vue
<template>
  <div>
      我的第一个页面的一个children
  </div>
</template>

<script>
export default {

}
</script>

<style>

</style>

// App.vue
<template>
  <div id="app">
    <router-view />
    <div class="routeInfo">
      {{routerinfo}}
    </div>
  </div>
</template>
<script>

export default {
  computed: {
    routerinfo () {
      let {name,meta,path,query,params,fullPath} = this.$route
      return {name,meta,path,query,params,fullPath}
    }
  }
}
</script>
<style lang="less">
#app {

</style>

// router/index.js
import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";

Vue.use(VueRouter);

const routes = [
  {
    path: "/",
    name: "Home",
    component: Home
  },
  {
    path: "/One",
    name: "One",
    component: () =>
      import(/* webpackChunkName: "one" */ "../views/one.vue"),
    children:[
      {
        path:'oneSon',  // 注意：此处的path不要加/ 
        name:'oneSon',
        component: () =>
          import(/* webpackChunkName: "one" */ "../views/oneSon.vue"),
      }
    ]
  },
  {
    path: "/Two",
    name: "Two",
    component: () =>
      import(/* webpackChunkName: "two" */ "../views/two.vue"),
  }
];

const router = new VueRouter({
  routes
});

export default router;
