这篇文章主要为大家详细介绍了微信小程序可滑动月日历组件的使用方法,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

微信小程序可滑动月日历组件

此日历可进行左右滑动,展示签到打卡信息,和大家分享一下。
如果样式变形,请检查是否有共用样式起冲突

展示一下效果图

在components组件文件夹下新建calendarMonth文件夹

直接上代码吧:

调用组件

//json文件调用
"usingComponents": {
   "calendarMonth": "../../components/calendarMonth/index"
}

页面调用组件

//workerClockData 传过去的数据 显示签到金额 和 记
<calendarMonth workerClockData="{{workerClockData}}"></calendarMonth>

要显示打卡数据要传入参数,格式为如下,格式为数组
