一、引言
在网上的某马那里学习了前端，在学Vue的时候有一个令我感兴趣的小案例（小黑记事本），于是稍微改了一下界面，增加了本地存储功能，做成了这个小项目
为了便于分享，遂把html,css和js放在了一起（当然平常不推荐这么做），背景图片也使用了在线图片，vue导包也是如此，故即使不访问服务器该文件仍需联网使用
推荐使用电脑打开，手机也可用浏览器打开（推荐横屏），需要的可在文末处自行下载
注意：该文件只用于交流学习！请勿商用！
二、项目展示
1.主界面
2.添加任务
可通过输入任务后回车或点击“添加任务”按钮来添加任务
3.储存功能
刷新或关掉浏览器后重新打开数据依然存在
4.删除功能
鼠标移动到任务模块上（或手机端手指点击任务）会出现删除按钮，点击按钮删除任务
5.其他功能
左下角有任务数量统计
点击右下角可清空任务
三、技术要点
localStorage浏览器本地存储
watch监视器（Vue基本功能等）
