2024-01-13 13:41:04

1.利用 {name:'组件名称',params:{参数1:数值,参数2:数值}}

<router-link v-bind:to="{name:'UserProfile',params:{id:1}}">个人信息</router-link>
<template>
  <div class="app">
    <el-container>
      <el-aside class="app-side app-side-left"
                :class="isCollapse ? 'app-side-collapsed' : 'app-side-expanded'">
        <div class="app-side-logo">
          <img src="@/assets/logo.png"
               :width="isCollapse ? '60' : '60'"
               height="60" />
        </div>
        <div>
          <!-- 我是样例菜单 -->
          <el-menu default-active="1-4-1"

          <div class="app-header-userinfo">
            <el-dropdown trigger="hover"
                         :hide-on-click="false">
              <span class="el-dropdown-link">
                {{ username }}

                <el-dropdown-item divided
                                  @click.native="logout">退出登录</el-dropdown-item>
              </el-dropdown-menu>
            </el-dropdown>
          </div>
        </el-header>

        <el-main class="app-body">
          <template>
            <router-view/>
          </template>
        </el-main>
      </el-container>
    </el-container>
  </div>
</template>

<script>
  export default {
    name: 'Container',
    data() {
      return {
        username: '',
        isCollapse: false
      }
    },
    methods: {
      toggleSideBar() {
        this.isCollapse = !this.isCollapse
      },
      logout: function () {
        this.$confirm('确认退出?', '提示', {})
          .then(() => {
            sessionStorage.removeItem('user');
            this.$router.push('/login');
          })
          .catch(() => { });
      },
      handleOpen(key, keyPath) {
        console.log(key, keyPath);
      },
      handleClose(key, keyPath) {
        console.log(key, keyPath);
      },
      handleSelect(key, keyPath) {
        console.log(key, keyPath);
      },
    },
    mounted: function () {
      let user = sessionStorage.getItem('user');
      if (user) {
        this.username = user;
      }
    },
  }
</script>

<style>
</style>

第一种方式传递和接收参数 {{$route.params.id}}

2.修改router中index.js中路由配置

/**
 * 配置路由
 */
import Vue from 'vue'
import Router from 'vue-router'

import Main from '../views/Main'
import Login from '../views/Login'
import UserList from '../views/user/List'
import UserProfile from '../views/user/Profile'


Vue.use(Router);

export default new Router({
  routes:[
    {
      path:'/login',
      component:Login
    },{
      path:'/main',
      component:Main,
      children:[ //嵌套路由
        {
          path:'/user/profile/:id',//id的参数和Main.vue传递的要对应
          name:'UserProfile',//组件名称，在Main.vue中导航使用
          component:UserProfile
        },
        {path:'/user/list',component:UserList}
      ]
    }
  ]
});

3.在展示的组件中 Profile.vue中接收传递的参数

<template>
  <div>
    <h1>个人信息</h1>
    {{$route.params.id}}
  </div>

</template>

<script>
    export default {
        name: "UserProfile"
    }
</script>

<style scoped>

</style>

第二种方式传递和接收参数  props：true

1.在路由配置中增加 props：true

/**
 * 配置路由
 */
import Vue from 'vue'
import Router from 'vue-router'

import Main from '../views/Main'
import Login from '../views/Login'
import UserList from '../views/user/List'
import UserProfile from '../views/user/Profile'


Vue.use(Router);

export default new Router({
  routes:[
    {
      path:'/login',
      component:Login
    },{
      path:'/main',
      component:Main,
      children:[ //嵌套路由
        {
          path:'/user/profile/:id',
          name:'UserProfile',
          component:UserProfile,
          props:true
        },
        {path:'/user/list',component:UserList}
      ]
    }
  ]
});

2.在接收页面 Profile.vue修改接收方式

<template>
  <div>
    <h1>个人信息</h1>
    {{id}}
  </div>

</template>

<script>
    export default {
      props:['id'],
      name: "UserProfile"
    }
</script>

<style scoped>

</style>

重定向配置

1.在路由配置中修改

/**
 * 配置路由
 */
import Vue from 'vue'
import Router from 'vue-router'

import Main from '../views/Main'
import Login from '../views/Login'
import UserList from '../views/user/List'
import UserProfile from '../views/user/Profile'


Vue.use(Router);

export default new Router({
  routes:[
    {
      path:'/login',
      component:Login
    },{
      path:'/main',
      component:Main,
      children:[ //嵌套路由
        {
          path:'/user/profile/:id',
          name:'UserProfile',
          component:UserProfile,
          props:true
        },
        {path:'/user/list',component:UserList}
      ]
    },
    {
      path:'/goHome',
      redirect:'/main'
    }
  ]
});

2.修改Main.vue

<template>
  <div class="app">
    <el-container>
      <el-aside class="app-side app-side-left"
                :class="isCollapse ? 'app-side-collapsed' : 'app-side-expanded'">
        <div class="app-side-logo">
          <img src="@/assets/logo.png"
               :width="isCollapse ? '60' : '60'"
               height="60" />
        </div>
        <div>
          <!-- 我是样例菜单 -->
          <el-menu default-active="1-4-1"
                   class="el-menu-vertical-demo"
                   @open="handleOpen"
                   :collapse="isCollapse">
            <el-submenu index="1">
              <template slot="title">

              <el-menu-item-group>
                <span slot="title">分组一</span>
                <el-menu-item index="1-1">
                  <router-link v-bind:to="{name:'UserProfile',params:{id:1}}">个人信息</router-link>
                </el-menu-item>
                <el-menu-item index="1-2">
                  <router-link to="/user/list">用户列表</router-link>

              </el-menu-item-group>
              <el-submenu index="1-4">
                <span slot="title">选项4</span>
