【Vue3+Vite+TS】2.0 组件一：伸缩菜单

必备UI组件

伸缩菜单将用到以下几个组件：
Container 布局容器
Menu 菜单

组件设计

修改路由：
srcrouterindex.ts

import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router'

import Home from '../views/Home/index.vue'
import Container from '../components/baseline/container/src/index.vue'

const routes: RouteRecordRaw[] = [
    {
        path: '/',
        component: Container,
        children: [
            {
                path: '/',
                component: Home,
            },
        ],
    },
]

const router = createRouter({
    routes,
    history: createWebHistory(),
})
export default router

新建srccomponentsbaselinecontainersrcindex.vue

修改srcApp.vue

效果如下:

利用el-menu的collapse属性，可以达到伸缩的效果。

发现按钮没有并过来。参考官网的举例，优化：

优化全局样式

新建srcstylebase.scss

* {
    margin: 0;
    padding: 0;
}
svg {
    width: 1em;
    height: 1em;
}
html,
body,
#app,
.el-container,
.el-menu {
    height: 100%;
}

html {
    font-size: 100px;
}
body {
    font-size: 0.12rem;
}

新建srcstyleindex.scss

@import './base.scss';

修改srcmain.ts

import { createApp } from 'vue'
import App from './App.vue'
import router from './router/index'

import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import * as Icons from '@element-plus/icons-vue'
import { toLine } from './utils'

import './style/index.scss'

const app = createApp(App)

//全局组件注册，牺牲一些性能，但方便使用
//封装成el-icon-xxx
for (let i in Icons) {
    // console.log(`i:`, i)
    // console.log('Icons[i]', (Icons as any)[i])
    app.component(`el-icon-${toLine(i)}`, (Icons as any)[i])
}

app.use(router)
app.use(ElementPlus)
app.mount('#app')

修改srcApp.vue

这样，可以100px=1rem，修改srccomponentsbaselinecontainersrcindex.vue，可以调整为：

组件抽离

修改srccomponentsbaselinecontainersrcindex.vue

新建srccomponentsbaselinecontainersrcnavHeaderindex.vue

新建srccomponentsbaselinecontainersrcnavAsideindex.vue

样式优化

修改srccomponentsbaselinecontainersrcindex.vue

修改srccomponentsbaselinecontainersrcnavHeaderindex.vue
