1.首先看看效果吧

uni-app入门------便签APP的项目记录_css

2.项目的功能

(1)创建便签

(2)对便签进行管理(待办/已完成)

3.项目的缺点

(1)没有服务接口,只是个UI功能而已,也就是说,创建了便签之后,在退出了APP再进来数据就没有了。以后可能会加数据存储吧,有时间的话。

(2)功能比较单一

4.项目用到的技术

Vue.js css javascript html uni-app框架

5.用uni-app框架做出来的APP的优点?

可以跨多端运行!!!

uni-app入门------便签APP的项目记录_uni-app_02

真的太香了!!!

目前我测了便签项目微信小程序和安卓版本的,都可以运行哦!

此处附上uni-app的官网:​​https://uniapp.dcloud.io/​

6.项目总结:

为了入门这个uni-app,我专门去学习了HTML、css、JavaScript、Vue.js,当开始学习uni-app的时候,我怀着无比激动的心情,当项目成功发布到小程序和原生APP的时候,真的很开心,这样意味着一套代码可以运行在多个平台意味着我的竞争力又提高了那么一丢丢…但是这只是刚刚开始,我会继续深入学习的,因为我真的太喜欢这个跨多端的框架了。之后,我可能会用uni-app去实现一个和我毕业设计一样的APP的功能!加油吧!
