- 核心代码
- 效果展示
- 源码下载

文章说明

随着移动端使用占比升高，手机端的App、小程序也成了一些场景下的首选；采用uni-pp开发此类应用具有很多优势，它可以直接使用vue3进行开发，同时它内置的许多小功能可以节省许多造轮子的操作，且可以将一套源码直接编译成App和小程序，非常方便

本文主要是为了学习uni-app的简单使用，采用原生自带的示例项目，再简单编辑了一些小功能，作为示例项目，可以在后续将PC端的我Web页面迁移到uni-app的架构

采用的开发工具是HBuilder，可在官网直接下载；同时在创建项目时可以选择官方自带的示例demo，在那里面可以直接找到基本组件的使用示例，学习起来非常方便
