Vue路由讲解

1>router-link和router-view组件

2>路由配置

a.动态路由

import Home from "@/views/Home.vue";

export default [
  {
    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")
  },
  {
    path: "/argu/:name",//动态路由
    component: () => import("@/views/argu.vue")
  }
];

<template>
  <div>
    <!-- 拿到动态路由的参数 $route:当前加载页面的路由对象 -->
    {{$route.params.name}}
  </div>
</template>

<script>
export default {
  //
};
</script>

b.嵌套路由

import Home from "@/views/Home.vue";
export default [
  {
    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")
  },
  {
    path: "/argu/:name",
    component: () => import("@/views/argu.vue")
  },
  //嵌套路由的使用
  {
    path: "/parent",
    component: () => import("@/views/parent.vue"),
    children: [
      {
        path: "child",//此处不能加/
        component: () => import("@/views/child.vue")
      }
    ]
  }
];

child.vue:

<template>
  <div>I am child</div>
</template>

c.命名路由

import Home from "@/views/Home.vue";

export default [
  {
    path: "/",
    name: "home",//加上name属性  命名路由
    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")
  },
  {
    path: "/argu/:name",
    component: () => import("@/views/argu.vue")
  },
  //嵌套路由的使用
  {
    path: "/parent",
    component: () => import("@/views/parent.vue"),
    children: [
      {
        path: "child",
        component: () => import("@/views/child.vue")
      }
    ]
  }
];

d.命名视图

import Home from "@/views/Home.vue";

export default [
  {
    path: "/",
    name: "home",//加上name属性  命名路由
    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")
  },
  {
    path: "/argu/:name",
    component: () => import("@/views/argu.vue")
  },
  //嵌套路由的使用
  {
    path: "/parent",
    component: () => import("@/views/parent.vue"),
    children: [
      {
        path: "child",
        component: () => import("@/views/child.vue")
      }
    ]
  },
  {
    path: "/named_view",
    //加载多个组件 用复数
    components: {
      default: () => import("@/views/child.vue"),
      email: () => import("@/views/email.vue"),
      tel:()=>import("@/views/tel.vue")
    }
  }
];

<template>
  <div id="app">
    <div id="nav">
      <router-link to="/">Home</router-link>|
      <!-- 命名路由 -->
      <router-link :to="{name:'about'}">About</router-link>
      <!-- <router-link to="/about">About</router-link> -->
    </div>
    <!-- 路由视图组件 -->
    <router-view/>
    <router-view name="email"/>
    <router-view name="tel"/>
  </div>
</template>

child.vue

<template>
  <div>I am child</div>
</template>

email.vue

<template>
  <div>email:07807958@qq.com</div>
</template>

tel.vue

<template>
  <div>tel:18976543210</div>
</template>

打开浏览器：http://localhost:8080/#/named_view

 打开调试工具，可以直观的看出各路由：

3>JS操作路由(编程式导航)

4>重定向和别名

import Home from "@/views/Home.vue";

export default [
  {
    path: "/",
    name: "home", //加上name属性  命名路由
    component: Home
  },
  {
    path: "/main",
    // redirect: "/",

    // redirect: {
    //   name:"home"
    // }
    
    redirect: to => {
      //console.log(to);
      // return {
      //   name:"home"
      // }
      return '/'
    }
  }
];

console.log(to)输出信息：

路由别名：

export default [
  {
    path: "/",
    alias:'/home_page',
    name: "home", //加上name属性  命名路由
    component: Home
  }]
