小程序日历控件分享

之前小程序开发需要用到日历控件，但是关于小程序可用的实在资源有限，于是就自己写了一个，如今项目上线后将它分享出来，希望能帮到需要的人。
效果图：

JS 代码：

dateData: function () {
    let dataAll = []//总日历数据
    let dataAll2 = []//总日历数据
    let dataMonth = []//月日历数据
    let date = new Date//当前日期
    let year = date.getFullYear()//当前年
    let week = date.getDay();//当天星期几
    let weeks=[]
    let month = date.getMonth() + 1//当前月份
    let day = date.getDate()//当天
    let daysCount = 100//一共显示多少天
    let dayscNow = 0//计数器
    let monthList = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]//月份列表
    let nowMonthList=[]//本年剩余年份
    for (let i = month;i<13;i++){
      nowMonthList.push(i)
    }
    let yearList = [year]//年份最大可能
    for (let i = 0; i < daysCount/365+2;i++){
      yearList.push(year+i+1)
    }    
    let leapYear = function (Year) {//判断是否闰年 
      if (((Year % 4) == 0) && ((Year % 100) != 0) || ((Year % 400) == 0)) {
        return (true);
      } else { return (false); }
    }
    for (let i = 0; i < yearList.length;i++){//遍历年
      let mList
      if (yearList[i] == year){//判断当前年份
        mList = nowMonthList
      }else{
        mList = monthList
      }
      for (let j = 0; j < mList.length;j++){//循环月份
        dataMonth=[]
        let t_days = [31, 28 + leapYear(yearList[i]), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
        let t_days_thisYear=[]
        if (yearList[i] == year){
          for (let m = 0; m<nowMonthList.length;m++){
            t_days_thisYear.push(t_days[mList[m]-1])
          }
          t_days = t_days_thisYear
        } else {
          t_days = [31, 28 + leapYear(yearList[i]), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
        }
        for (let k = 0; k < t_days[j];k++){//循环每天
          dayscNow++
          let nowData
          if (dayscNow < daysCount) {//如果计数器没满
            let days = k + 1
            if (days < 10) {
              days = "0" + days
            }
            if (yearList[i] == year && mList[j] == month){//判断当年当月
              if (k + 1 >= day) {
                nowData = {
                  year: yearList[i],
                  month: mList[j],
                  day: k + 1,
                  date: yearList[i] + "" + mList[j] + days,
                  selected: 0,
                  re: yearList[i] + "-" + mList[j] + "-" + days,
                }
                dataMonth.push(nowData)
                if (k+1 == day) {
                  let date = new Date(yearList[i] + "-" + mList[j] + "-" + (k + 1))
                  let weekss = date.getDay()//获取每个月第一天是周几
                  weeks.push(weekss)
                }
              }
            }            else {//其他情况
              nowData = {//组装自己需要的数据
                year: yearList[i],
                month: mList[j],
                day: k + 1,
                date: yearList[i] + "" + mList[j] + days,
                selected: 0,
                re: yearList[i] + "-" + mList[j] + "-" + days,
              }
              dataMonth.push(nowData)
              if (k == 0) {
                let date = new Date(yearList[i] + "-" + mList[j] + "-" + k + 1)
                let weekss = date.getDay()//获取每个月第一天是周几
                weeks.push(weekss)
              }
            }
          }else{
            break
          }
        }
        dataAll.push(dataMonth)
      }
    }
    for (let i = 0; i < dataAll.length;i++){
      if (dataAll[i].length!=0){
        dataAll2.push(dataAll[i]);
      }
    }
    this.setData({
      date: dataAll2,
      weeks: weeks
    })
  },

以上代码主要功能是作为数据源渲染
wxml 代码：

<view class="headbox2">
  <view class="headdate">日</view>
  <view class="headdate">一</view>
  <view class="headdate">二</view>
  <view class="headdate">三</view>
  <view class="headdate">四</view>
  <view class="headdate">五</view>
  <view class="headdate">六</view>
</view>
<view class="headbox">
  <view class="headdate">日</view>
  <view class="headdate">一</view>
  <view class="headdate">二</view>
  <view class="headdate">三</view>
  <view class="headdate">四</view>
  <view class="headdate">五</view>
  <view class="headdate">六</view>
</view>
<view class="mouth" wx:for="{{date}}" wx:for-item="date" wx:for-index="index">
  <view class="mouthhead">{{date[index].year}}年{{date[index].month}}月</view>
  <view class="daybox">
  <view class="day" wx:if="{{weeks[index]>0}}"></view>
  <view class="day" wx:if="{{weeks[index]>1}}"></view>
  <view class="day" wx:if="{{weeks[index]>2}}"></view>
  <view class="day" wx:if="{{weeks[index]>3}}"></view>
  <view class="day" wx:if="{{weeks[index]>4}}"></view>
  <view class="day" wx:if="{{weeks[index]>5}}"></view>
  <view class="day {{item.selected == 1 ? 'bc':''}}" wx:for="{{date}}" wx:for-index="idx" data-index="{{index}}" data-indexs="{{idx}}" bindtap="selectday">
    <view class="actname {{item.selected == 1 ? 'bc2':''}}">{{date[idx].act.subject}}</view>
    {{date[idx].day}}
    <view class="actname2 {{item.selected == 1 ? 'bc2':''}}" wx:if="{{date[idx].act.rate}}">{{date[idx].act.rate/10}}折</view>
  </view>
  </view>
</view>
<view class="none88" wx:if="{{pagetype=='day'}}"></view>
<view class="fixedbtn" bindtap="submitbtn" wx:if="{{pagetype=='day'}}">确认选择</view>

将数据渲染至 wxml
