发布时间：2018-06-08 10:15 所属栏目：小程序开发教程
微信小程序的日历选择，主要针对酒店选择时间段的日历，带有公历的节日。
主要函数：
通过选择入住与离店时间，记录对应的时间段，判断选择的开始时间和结束时间，通过改变背影颜色连成对应时间段。
selectDataMarkLine: function () {
let dateList = this.data.dateList;
let { checkInDate, checkOutDate } = wx.getStorageSync("ROOM_SOURCE_DATE");
let curreInid = checkInDate.substr(0, 4) + "-" + (checkInDate.substr(5, 2) < 10 ? checkInDate.substr(6, 1) : checkInDate.substr(5, 2));//选择入住的id
let curreOutid = checkOutDate.substr(0, 4) + "-" + (checkOutDate.substr(5, 2) < 10 ? checkOutDate.substr(6, 1) : checkOutDate.substr(5, 2));//选择离店的id
let dayIn = checkInDate.substr(8, 2) >= 10 ? checkInDate.substr(8, 2) : checkInDate.substr(9, 1);//选择入住的天id
let dayOut = checkOutDate.substr(8, 2) >= 10 ? checkOutDate.substr(8, 2) : checkOutDate.substr(9, 1);//选择离店的天id
let monthIn = checkInDate.substr(5, 2) >= 10 ? checkInDate.substr(5, 2) : checkInDate.substr(6, 1);//选择入店的月id
let monthOut = checkOutDate.substr(5, 2) >= 10 ? checkOutDate.substr(5, 2) : checkOutDate.substr(6, 1);//选择离店的月id
if (curreInid == curreOutid) {//入住与离店是当月的情况
for (let i = 0; i < dateList.length; i++) {
if (dateList[i].id == curreInid) {
let days = dateList[i].days;
for (let k = 0; k < days.length; k++) {
if (days[k].day >= dayIn && days[k].day <= dayOut) {
days[k].class = days[k].class + ' bgitem';
}
if (days[k].day == dayIn) {
days[k].class = days[k].class + ' active';
days[k].inday = true;
}
if (days[k].day == dayOut) {
days[k].class = days[k].class + ' active';
days[k].outday = true;
}
}
}
}
} else {//跨月
for (let j = 0; j < dateList.length; j++) {
if (dateList[j].month == monthIn) {//入住的开始月份
let days = dateList[j].days;
for (let k = 0; k < days.length; k++) {
if (days[k].day >= dayIn) {
days[k].class = days[k].class + ' bgitem';
}
if (days[k].day == dayIn) {
days[k].class = days[k].class + ' active';
days[k].inday = true;
}
}
} else {//入住跨月月份
if (dateList[j].month < monthOut) {//离店中间的月份
let days = dateList[j].days;
for (let k = 0; k < days.length; k++) {
days[k].class = days[k].class + ' bgitem';
}
} else if (dateList[j].month == monthOut) {//离店最后的月份
let days = dateList[j].days;
for (let k = 0; k < days.length; k++) {
if (days[k].day <= dayOut) {
days[k].class = days[k].class + ' bgitem';
}
if (days[k].day == dayOut) {
days[k].class = days[k].class + ' active';
days[k].outday = true;
}
}
}
}
}
}
this.setData({
dateList: dateList
})
},
