Vue 参数传递及重定向
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"
class="el-menu-vertical-demo"
@open="handleOpen"
:collapse="isCollapse">
<el-submenu index="1">
<template slot="title">
<i class="el-icon-location"></i>
<span slot="title">系统维护</span>
</template>
<el-menu-item-group>
<span slot="title">分组一</span>
<el-menu-item index="1-1">
<!--name:组件名 params：参数，需要对象，用v-bind绑定-->
<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>
</el-menu-item-group>
<el-menu-item-group title="分组2">
<el-menu-item index="1-3">选项3</el-menu-item>
</el-menu-item-group>
<el-submenu index="1-4">
<span slot="title">选项4</span>
<el-menu-item index="1-4-1">选项1</el-menu-item>
</el-submenu>
</el-submenu>
<el-menu-item index="2">
<i class="el-icon-menu"></i>
<span slot="title">导航二</span>
</el-menu-item>
<el-menu-item index="3"
disabled>
<i class="el-icon-document"></i>
<span slot="title">导航三</span>
</el-menu-item>
<el-menu-item index="4">
<i class="el-icon-setting"></i>
<span slot="title">导航四</span>
</el-menu-item>
</el-menu>
</div>
</el-aside>
<el-container>
<el-header class="app-header">
<div style="width: 60px; cursor: pointer;"
@click.prevent="toggleSideBar">
<i v-show="!isCollapse" class="el-icon-d-arrow-left"></i>
<i v-show="isCollapse" class="el-icon-d-arrow-right"></i>
</div>
<!-- 我是样例菜单 -->
<el-menu default-active="1"
class="el-menu-demo tab-page"
mode="horizontal"
@select="handleSelect"
active-text-color="#409EFF">
<el-menu-item index="1">处理中心</el-menu-item>
<el-submenu index="2">
<template slot="title">我的工作台</template>
<el-menu-item index="2-1">选项1</el-menu-item>
<el-menu-item index="2-2">选项2</el-menu-item>
<el-menu-item index="2-3">选项3</el-menu-item>
<el-submenu index="2-4">
<template slot="title">选项4</template>
<el-menu-item index="2-4-1">选项1</el-menu-item>
<el-menu-item index="2-4-2">选项2</el-menu-item>
<el-menu-item index="2-4-3">选项3</el-menu-item>
</el-submenu>
</el-submenu>
<el-menu-item index="3"
disabled>消息中心</el-menu-item>
<el-menu-item index="4">
<a href="#">订单管理</a>

</el-menu>
<div class="app-header-userinfo">
<el-dropdown trigger="hover"
:hide-on-click="false">
<span class="el-dropdown-link">
{{ username }}
<i class="el-icon-arrow-down el-icon--right"></i>
</span>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item>我的消息</el-dropdown-item>
<el-dropdown-item>设置</el-dropdown-item>
<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'">
