如何实现h5的抽奖功能

示例:

使用的是一个插件可以在多种环境下运行的插件:九宫格 LuckyGrid | 基于 Js / TS / Vue / React / 微信小程序 / uni-app / Taro 的【大转盘 & 九宫格 & 老虎机】抽奖插件

安装插件

# npm 安装
npm install @lucky-canvas/vue@latest

# 或者 yarn 安装
yarn add @lucky-canvas/vue@latest

按需引入(就当前文件使用)

import { LuckyWheel, LuckyGrid } from 'vue-luck-draw'

?仅供参考,基础样式修改可以查看官网文档修改在 Vue 中使用 | 基于 Js / TS / Vue / React / 微信小程序 / uni-app / Taro 的【大转盘 & 九宫格 & 老虎机】抽奖插件
