小程序日历打卡功能
maidu_xbd 人气:0一、效果图展示
老惯例,先上效果图
二、实现思路
1、日历展示
例如下图中:
2021月7月打卡日历页面,共35个日期数据,上月残余4天+本月31天;
2021月6月打卡日历页面,共35个日期数据,上月残余2天+本月30天+下月残余3天;
2021月5月打卡日历页面,共42个日期数据,上月残余6天+本月31天+下月残余5天。
【结论】打卡日历页面存在展示35个或42个日期数据的情况,35个或42个日期数据=当前显示月所有日期数据+上月残余尾部日期+下月残余头部日期。
计算出每个月的日期天数,获取本月1号是周几,上月残余天数=本月1号的星期X的X数(比如,2021年7月1日是星期四,则上月残余4天),假设 a=35-本月天数-上月残余天数。如果a>=0,则下月残余天数=a;如果a<0,则下月残余天数=7+a (比如2021年5月,35-37=-2;7+(-2)=5)
2、打卡功能
打卡实现的功能:可打卡的日期为今日日期或今日日期之前未打卡过的日期。
如图:今日日期为绿色圆形背景,当前点击日期为橙色圆形背景;可打卡时,打卡按钮背景为蓝色,不可打卡时,打卡背景为灰色;√ 代表已打卡。
通过数据库查询当前已打卡的数据,已打卡的数据需要设置打卡按钮禁用标志。打卡按钮禁用的情况(1)页面初始化时,未点击任何日期(2)当前点击的日期在今天之后(3)当前日期在今天之前但已打卡。
点击打卡,记录打卡日期并保存至数据库。
三、代码
1、数据库数据
2、日历组件
【calendar.wxml】
代码里使用了WXS页内脚本,渲染“已打卡”的标志(√)
