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> <view>日</view> <view>一</view> <view>二</view> <view>三</view> <view>四</view> <view>五</view> <view>六</view> </view> <view> <view>日</view> <view>一</view> <view>二</view> <view>三</view> <view>四</view> <view>五</view> <view>六</view> </view> <view wx:for="{{date}}" wx:for-item="date" wx:for-index="index"> <view>{{date[index].year}}年{{date[index].month}}月</view> <view> <view wx:if="{{weeks[index]>0}}"></view> <view wx:if="{{weeks[index]>1}}"></view> <view wx:if="{{weeks[index]>2}}"></view> <view wx:if="{{weeks[index]>3}}"></view> <view wx:if="{{weeks[index]>4}}"></view> <view wx:if="{{weeks[index]>5}}"></view> <view wx:for="{{date}}" wx:for-index="idx" data-index="{{index}}" data-indexs="{{idx}}" bindtap="selectday"> <view>{{date[idx].act.subject}}</view> {{date[idx].day}} <view wx:if="{{date[idx].act.rate}}">{{date[idx].act.rate/10}}折</view> </view> </view> </view> <view wx:if="{{pagetype=='day'}}"></view> <view bindtap="submitbtn" wx:if="{{pagetype=='day'}}">确认选择</view>
将数据渲染至wxml
wxss样式代码：
.headdate{ height: 30px; background-color: white; flex:1; text-align: center; line-height: 30px; } .headbox{ display: flex; display: -webkit-flex; border-bottom: 1px solid #e5e5e5; } .headbox2{ display: flex; position: fixed; width: 750rpx; display: -webkit-flex; border-bottom: 1px solid #e5e5e5; background-color: white; z-index: 2; } .mouthhead{ height: 88rpx; background-color: #f4f4f4; width: 750rpx; line-height: 88rpx; text-align: center; } .mouth{ /* background-color: white; */ /* padding-top: 10rpx; padding-bottom: 10rpx; */ } .daybox{ background-color: white; padding-top: 10rpx; padding-bottom: 10rpx; } .day{ width: 107rpx; height: 107rpx; line-height: 107rpx; text-align: center; display: inline-block; position: relative; top: 0; margin-top: -10rpx; overflow: hidden; color: #353535; font-size: 34rpx; } .day2{ color: #04babe; width: 107rpx; height: 107rpx; line-height: 107rpx; text-align: center; display: inline-block; position: relative; bottom: 0; margin-top: 0; } .actname{ color: #04babe; position: absolute; font-size: 20rpx; top: -30rpx; width: 107rpx; text-align: center; } .actname2{ color: #04babe; position: absolute; font-size: 20rpx; bottom: -30rpx; width: 107rpx; text-align: center; } .bc{ background-color: #04babe; color: white!important; } .bc2{ color: white!important; } .none88{ height: 88rpx; width: 750rpx; }
