JavaScript获取一个范围内日期的方法

Date.prototype.addDays = function(days) {
  var dat = new Date(this.valueOf());
  dat.setDate(dat.getDate() + days);
  return dat;
};
function getDates(startDate, stopDate) {
  var dateArray = [];
  var currentDate = startDate;
  while (currentDate <= stopDate) {
    dateArray.push(self.formatDate(currentDate));
    currentDate = currentDate.addDays(1);
  }
  return dateArray;
}
