将您提供的 Vue 3 + TypeScript 的代码改写成 JavaScript 代码，具体如下：
<template><el-radio-group v-model="isCollapse" style="margin-bottom: 20px"><el-radio-button :value="false">expand</el-radio-button><el-radio-button :value="true">collapse</el-radio-button></el-radio-group><el-menudefault-active="2"class="el-menu-vertical-demo":collapse="isCollapse"@open="handleOpen"@close="handleClose"><el-sub-menu index="1"><template #title><el-icon><location /></el-icon><span>Navigator One</span></template><el-menu-item-group><template #title><span>Group One</span></template><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-menu-item-group title="Group Two"><el-menu-item index="1-3">item three</el-menu-item></el-menu-item-group><el-sub-menu index="1-4"><template #title><span>item four</span></template><el-menu-item index="1-4-1">item one</el-menu-item></el-sub-menu></el-sub-menu><el-menu-item index="2"><el-icon><icon-menu /></el-icon><template #title>Navigator Two</template></el-menu-item>< el - menu - item index = "3" disabled ><el - icon > <document / > </ el - icon ><template #title > Navigator Three </ template ></ el - menu - item ><el - menu - item index = "4" ><el - icon > <setting / > </ el - icon ><template #title > Navigator Four </ template ></ el - menu - item ></ el - menu ></ template ><script lang="js">import { ref } from 'vue';import {Document,Menu as IconMenu,Location,Setting,} from '@element-plus/icons-vue';export default {setup() {const isCollapse = ref(true);const handleOpen = (key, keyPath) => {console.log(key, keyPath);};const handleClose = (key, keyPath) => {console.log(key, keyPath);};return {isCollapse,handleOpen,handleClose};}};</script><style scoped>.el-menu-vertical-demo:not(.el-menu--collapse) {width: 200px;min-height: 400px;}</style>
在这个改写的版本中，<script> 标签中的 lang 属性被移除，并且使用了普通的 JavaScript（而不是 TypeScript）。同时也去掉了类型声明，使得其符合 JavaScript 的语法规范。
