js 获取两个时间段时间数组

getDateAll(starDay, endDay) {
  var arr = [];
  var dates = [];
  // 设置两个日期UTC时间
  var db = new Date(starDay);
  var de = new Date(endDay);
  // 获取两个日期GTM时间
  var s = db.getTime() - 24 * 60 * 60 * 1000;
  var d = de.getTime() - 24 * 60 * 60 * 1000;
  // 获取到两个日期之间的每一天的毫秒数
  for (var i = s; i <= d; ) {
      i = i + 24 * 60 * 60 * 1000;
      arr.push(parseInt(i));
  }
  // 获取每一天的时间  YY-MM-DD
  for (var j in arr) {
      var time = new Date(arr[j]);
      var year = time.getFullYear(time);
      var mouth =
          time.getMonth() + 1 >= 10
              ? time.getMonth() + 1
              : "0" + (time.getMonth() + 1);
