2个日期之间的类型脚本过滤

Question

我过滤了您在图片中看到的搜索屏幕，但无法正常工作。当您在付款当天写03.03.2020时，它将带走所有记录。我想过滤付款日期和我的登录日期，并在两者之间进行记录。如何修复代码？

所以我认为问题是您需要检查过滤器中checkInDate和payDate是否都匹配。在当前代码中，一次仅检查其中一个值

我认为解决方法可能是这样的：

private isEqual(date1: Date, date2: Date) {
    return date1.getDate() == date2.getDate() && date1.getMonth() == date2.getMonth() && date1.getFullYear() == date2.getFullYear();
}

private isDataEqualToDate(value1: any, date2: Date) {
   if (value1 == null) return true;
   return isEqual(new Date(value1), date2);
}

private getFilteredHotels() {
   return this.hotels.filter(
     x => this.isDataEqualToDate(this.startDate, new Date(x.checkInDate))
       && this.isDataEqualToDate(this.endDate, new Date(x.payDate))
   );
}

changeStartDate() {
    this.dsHotels.data = this.getFilteredHotels();

}

changeEndDate() {
    this.dsHotels.data = this.getFilteredHotels();
}
