小程序日歷控件使用方法詳解

更新時(shí)間：2018年12月29日 09:29:28 作者：羅忠浩

這篇文章主要為大家詳細(xì)介紹了小程序日歷控件的使用方法，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

之前小程序開發(fā)需要用到日歷控件，但是關(guān)于小程序可用的實(shí)在資源有限，于是就自己寫了一個(gè)，如今項(xiàng)目上線后將它分享出來，希望能幫到需要的人。

效果圖：

JS代碼：

dateData: function () {
  let dataAll = []//總?cè)諝v數(shù)據(jù)
  let dataAll2 = []//總?cè)諝v數(shù)據(jù)
  let dataMonth = []//月日歷數(shù)據(jù)
  let date = new Date//當(dāng)前日期
  let year = date.getFullYear()//當(dāng)前年
  let week = date.getDay();//當(dāng)天星期幾
  let weeks=[]
  let month = date.getMonth() + 1//當(dāng)前月份
  let day = date.getDate()//當(dāng)天
  let daysCount = 100//一共顯示多少天
  let dayscNow = 0//計(jì)數(shù)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) {//判斷是否閏年 
   if (((Year % 4) == 0) && ((Year % 100) != 0) || ((Year % 400) == 0)) {
    return (true);
   } else { return (false); }
  }
  for (let i = 0; i < yearList.length;i++){//遍歷年
   let mList
   if (yearList[i] == year){//判斷當(dāng)前年份
    mList = nowMonthList
   }else{
    mList = monthList
   }
   for (let j = 0; j < mList.length;j++){//循環(huán)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++){//循環(huán)每天
     dayscNow++
     let nowData
     if (dayscNow < daysCount) {//如果計(jì)數(shù)器沒滿
      let days = k + 1
      if (days < 10) {
       days = "0" + days
      }
      if (yearList[i] == year && mList[j] == month){//判斷當(dāng)年當(dāng)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()//獲取每個(gè)月第一天是周幾
         weeks.push(weekss)
        }
       }
      }      else {//其他情況
       nowData = {//組裝自己需要的數(shù)據(jù)
        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()//獲取每個(gè)月第一天是周幾
        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
  })
 },

以上代碼主要功能是作為數(shù)據(jù)源渲染

wxml代碼：

<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'}}">確認(rèn)選擇</view>

將數(shù)據(jù)渲染至wxml
