本文介绍了如何在Vite+Vue3的项目中结合Element-UI来实现侧边栏的设计。首先引入Element-UI的侧边栏样式并进行适当的修改，然后在模板中书写渲染代码，利用v-for指令动态遍历数据，最终展示出具有动态效果的侧边栏。

1.1 引入element-ui 侧边栏样式适当修改

<el-menu class="el-menu-vertical-demo">
  <el-sub-menu index="1">
     <template #title>
        <el-icon><location /></el-icon>
        <span>导航栏1</span>
     </template>
     <el-menu-item-group title="Group One">
        <el-menu-item index="1-1">item one</el-menu-item>
        <el-menu-item index="1-2">item two</el-menu-item>
      </el-menu-item-group>
   </el-sub-menu>
 </el-menu>

1.2 书写要渲染的代码

<script>
export default {
  setup() {
    const list = [
      {
        path: "/user",
        name: "user",
        label: "用户管理",
        icon: "user",
        url: "UserManage/UserManage",
      },
      {
        label: "其他",
        icon: "location",
        path:"/other",
        children: [
          {
            path: "/page1",
            name: "page1",
            label: "页面1",
            icon: "setting",
            url: "Other/PageOne",
          },
          {
            path: "/page2",
            name: "page2",
            label: "页面2",
            icon: "setting",
            url: "Other/PageTwo",
          },
        ],
      },
    ];

    const noChildren = ()=>{
      return list.filter((item)=>!item.children);
    };

    const hasChildren = ()=>{
      return list.filter((item)=>item.children);
    };

    return {
      noChildren,
      hasChildren,
    }


  },
};
</script>

1.3 template > v-for遍历

<template>
  <el-aside width="200px">
    <el-menu class="el-menu-vertical-demo">
      <el-menu-item :index="item.path" v-for="item in noChildren()" :key="item.path">
        <!-- 动态引入icon -->
        <!-- <el-icon><icon-menu /></el-icon> -->
        <component class="icons" :is="item.icon"></component>
        <!-- <span>一级菜单</span> -->
        <span>{{item.label}}</span>
      </el-menu-item>
      <el-sub-menu :index="item.label" v-for="item in hasChildren()" :key="item.path">
        <template #title>
           <component class="icons" :is="item.icon"></component>
        <span>{{item.label}}</span>
        </template>
        <el-menu-item-group>
          <el-menu-item :index="subItem.path" v-for="(subItem,subIndex) in item.children" :key="subIndex">
                    <component class="icons" :is="subItem.icon"></component>
        <span>{{subItem.label}}</span>
          </el-menu-item>
        </el-menu-item-group>
      </el-sub-menu>
    </el-menu>
  </el-aside>
</template>
