element.js
中添加import {
Container,
Header,
Aside,
Main
} from 'element-ui'
Vue.use(Container)
Vue.use(Header)
Vue.use(Aside)
Vue.use(Main)

element.js
中添加import {
Menu,
Submenu,
MenuItemGroup,
MenuItem
} from 'element-ui'
Vue.use(Menu)
Vue.use(Submenu)
Vue.use(MenuItemGroup)
Vue.use(MenuItem)
{{item.authName}}

通过axios请求拦截器添加token,保证拥有获取数据的权限
main.js
文件中添加// axios请求拦截
axios.interceptors.request.use(config => {
// 为请求头对象,添加 Token 验证的 Authorization 字段
config.headers.Authorization = window.sessionStorage.getItem('token')
return config
})
created() {
//获取到所有菜单
this.getMenuList()
},
methods: {
async getMenuList() {
const {data: res} = await this.$http.get('menus')
if (res.meta.status !== 200) return this.$message.error(res.meta.msg)
this.menulist = res.data
console.log(res)
},
}
data() {
return {
// 左侧菜单数据
menulist: [],
iconsObj: {
'125': 'iconfont icon-user',
'103': 'iconfont icon-tijikongjian',
'101': 'iconfont icon-shangpin',
'102': 'iconfont icon-danju',
'145': 'iconfont icon-baobiao'
},
}
}
.iconfont {
margin-right: 10px;
}
实现左侧菜单折叠和展开
<el-aside :width="isCollapse ? '64px' : '200px'">
<div class="toggle-button" @click="toggleCollapse">|||div>
el-aside>
.toggle-button {
background-color: #4a5064;
font-size: 10px;
line-height: 24px;
color: #fff;
text-align: center;
letter-spacing: 0.2em;
cursor: pointer;
}
<script>
export default {
data() {
return {
// 是否折叠
isCollapse: false,
}
},
methods: {
toggleCollapse() {
this.isCollapse = !this.isCollapse
}
}
}
</script>
Welcome.vue
index.js
中添加import Welcome from "../components/Welcome";
const routes = [
{
path: '/home',
component: Home,
redirect: '/welcome',
children:[
{
path: '/welcome',
component: Welcome
}
]
}
]
通过后台管理用户的账号信息,具体包括用户信息的展示、添加、修改、删除、角色分配、账号启用/注销等功能
用户信息列表展示
添加用户
修改用户
删除用户
启用或禁用用户
用户角色分配
面包屑导航 el-breadcrumb
Element-UI 栅格系统基本使用 el-row
表格布局 el-table、el-pagination
Users.vue
index.js
中添加import Users from "../components/user/Users"
const routes = [
{
path: '/home',
component: Home,
redirect: '/welcome',
children:[
{
path: '/welcome',
component: Welcome
},
{
path: '/users',
component: Users
},
]
}
]
