微信小程序可滑動月日歷組件

此日歷可進行左右滑動，展示簽到打卡信息，和大家分享一下。
如果樣式變形，請檢查是否有共用樣式起沖突

展示一下效果圖

微信小程序可滑動月日歷組件使用詳解

在components組件文件夾下新建calendarMonth文件夾

直接上代碼吧：

調用組件

//json文件調用
"usingComponents": {
   "calendarMonth": "../../components/calendarMonth/index"
}

頁面調用組件

//workerClockData 傳過去的數據 顯示簽到金額 和 記
<calendarMonth workerClockData="{{workerClockData}}"></calendarMonth>

要顯示打卡數據要傳入參數，格式為如下，格式為數組
