JS automatically calculates hotel accommodation costs

This article mainly introduces the relevant information of javascript to obtain different prices per day within a date range (calculating the total price of stay). Friends in need can refer to the following

Code example

I was recently developing a small program project for a hotel and encountered such a problem.

The hotel room price is floating, and the price is different every day, hour or on a special date. If the user selects a house for the next 5 days, and the prices happen to be different during these 5 days, and there are special days, how to calculate the total price for the 5 days?

The following example lists all the dates within this date range based on the check-in date and check-out date:

You will use this function in several places, so To encapsulate: Create a separate js file

function Thedatefor(times,objroom){ // 日期段 objroom房间价格表，有星期和特殊日期
 var dateObj = []
 var feeroom = [] // 计算后总价格表
 var str = times[0].split("-") // 入住日期
 var end = times[1].split("-") //离店日期
 var strs = new Date();
 strs.setUTCFullYear(str[0], str[1] - 1, str[2]); //设置年份
 var ends = new Date();
 ends.setUTCFullYear(end[0], end[1] - 1, end[2]); //设置年份
 var strdate = strs.getTime(); //毫秒
 var enddate = ends.getTime(); // 毫秒
 for (var b = strdate; b <= enddate;) { // 遍历出所有日期段
 dateObj.push((new Date(parseInt(b))).format().toString());
 b = b + 24 * 60 * 60 * 1000;
 }
 for (var b = 0; b < dateObj.length;b++){  //dateObj拿到的所有日期
 var timedate = dateAllArr[b].split("-")  
 var getDays = new Date(dateObj[b]).getDay() == 0 ? 7 : new 
Date(dateObj[b]).getDay() //这里可以转换成星期几的
 for (var h = 0; h < (objroom.length - 1);h++){ 
  if (parseInt(timedate[0] + timedate[1] + timedate[2]) == objroom[h].match){ // 对比特殊日
  feeroom.push({ fee: objroom[h].fee, date: dateObj[b]})
  }//根据星期几和特殊日期来获取每天的价格
  if (getDays == objroom[h].match) { //对比星期
  feeroom.push({ fee: objroom[h].fee, date: dateObj[b] })
  }
 }
 }
 return feeroom //最后列出每天的价格，和日期返回
}

times. The check-in date and check-out date format is: '[2018-01-20,2018-01-26]', objroom is a future Daily price list for this room for a week.
