关于如何计算星座的记事本

 下面是根据年月日时间获取所属星座

 /// <summary>
        /// 根据生日过的星座
        /// </summary>
        /// <param name="birthday"></param>
        /// <returns></returns>
        public string GetAtomByDateTime(DateTime birthday)
        {
            string ret = "外星人啊";
            float birthdayF = 0.00F;
            if(birthday.Month == 1 && birthday.Day < 20)
            {
                birthdayF = float.Parse(string.Format("13.{0}", birthday.Day));
            }
            else
            {
                birthdayF = float.Parse(string.Format("{0}.{1}", birthday.Month, birthday.Day));
            }
            float[] atomBound = { 1.20F, 2.19F, 3.21F, 4.20F, 5.21F, 6.22F, 7.23F, 8.23F, 9.23F, 10.24F, 11.23F, 12.22F, 13.20F };
            string[] atoms = { "水瓶座", "双鱼座", "白羊座", "金牛座", "双子座", "巨蟹座", "狮子座", "处女座", "天秤座", "天蝎座", "射手座", "摩羯座" };

            for (int i = 0; i < atomBound.Length -1; i++)
            {
                if (atomBound[i] <= birthdayF && atomBound[i + 1] > birthdayF)
                {
                    ret = atoms[i];
                    break;
                }
            }
            return ret;
        }

嘻嘻

js代码

function getAstro(month, day) {
            var s = "魔羯水瓶双鱼白羊金牛双子巨蟹狮子处女天秤天蝎射手魔羯";
            var arr = [20, 19, 21, 21, 21, 22, 23, 23, 23, 23, 22, 22];
            return s.substr(month * 2 - (day < arr[month - 1] ? 2 : 0), 2);
        }
    </script
