基于Vue3手写选课组件（含时区切换，拖拽选择）

环境说明

基于vue3+vite 无关联别的ui框架，组件化
初次使用vue3，技术菜，大佬勿喷

main.ts

 "moment": "^2.29.4","moment-timezone": "^0.5.41",

import moment from 'moment';
import momentTz from "moment-timezone";
import 'moment/dist/locale/zh-cn'
moment.locale('zh-cn')app.config.globalProperties.$moment = moment
// or
window.moment = moment

效果图
