计算两个日期时间内的每一周，不足一周的按照一周计算

JavaScript

function splitWeeks(startDate, endDate) {let start = new Date(startDate);let end = new Date(endDate);let weeks = [];let currentDate = new Date(start);let weekStart = new Date(currentDate);let weekEnd = new Date(currentDate);weekEnd.setDate(currentDate.getDate() + (7 - currentDate.getDay()));while (currentDate <= end) {if (weekEnd > end) {weekEnd = new Date(end);}let weekDates = [];let date = new Date(weekStart);while (date <= weekEnd) {let formattedDate = formatDate(date);let dayOfWeek = getDayOfWeek(date);weekDates.push({ date: formattedDate, weekday: dayOfWeek });date.setDate(date.getDate() + 1);}weeks.push(weekDates);currentDate.setDate(currentDate.getDate() + (7 - currentDate.getDay() + 1));weekStart = new Date(currentDate);weekEnd = new Date(currentDate);weekEnd.setDate(currentDate.getDate() + (7 - currentDate.getDay()));}return weeks;
}function formatDate(date) {let year = date.getFullYear();let month = (date.getMonth() + 1).toString().padStart(2, "0");let day = date.getDate().toString().padStart(2, "0");return `${year}-${month}-${day}`;
}function getDayOfWeek(date) {let dayOfWeek = date.getDay();let weekdays = ["星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六"];return weekdays[dayOfWeek];
}// 示例用法
let startDate = "2023-09-19";
let endDate = "2023-10-15";let result = splitWeeks(startDate, endDate);
console.log(result);
