JS實現生成一個周對應日期數組

/* 獲取日期和周 */getDateWeek() {/* 得到當前日期的時間戳 */const timestamp = Date.now()// const timestamp = new Date(2019, 7, 30, 0, 0, 0, 0).getTime()const dateWeek = Array.from(new Array(7)).map((_, i) => {/* 得到當前周每一天的時間戳 */const weekTimestamp = new Date(timestamp + i * 24 * 60 * 60 * 1000)const date = String(weekTimestamp.getMonth() + 1).padStart(2, '0') + '.' +String(new Date(weekTimestamp).getDate()).padStart(2, '0')/* 得到周幾后轉換 */let week = weekTimestamp.getDay()switch (week) {case 0:week = '周日'breakcase 1:week = '周一'breakcase 2:week = '周二'breakcase 3:week = '周三'breakcase 4:week = '周四'breakcase 5:week = '周五'breakcase 6:week = '周六'break}return {date,week }})console.log(dateWeek)
　　//得到如下結果
