js code to automatically obtain zodiac signs based on date of birth_javascript skills

I'm helpless~ I just didn't study hard when I was studying~ When I looked at JavaScript, one head suddenly turned into two. . . . . . . .
Fortunately, the Internet provides a very good database~ After reading it, and then making some changes myself, I can basically complete the task~ Write down an archive for future use

Copy code The code is as follows:

function xingzuo() {
var start = 1901, date=document.getElementById("txtDay") .value, month=document.getElementById("txtMonth").value;;
with (document.getElementById("txtXZ")){
if (month == 1 && date >=20 || month == 2 && date <=18) {value = "Aquarius";}
if (month == 1 && date > 31) {value = "Huh?";}
if (month = = 2 && date >=19 || month == 3 && date <=20) {value = "Pisces";}
if (month == 2 && date > 29) {value = "Say what ?";}
if (month == 3 && date >=21 || month == 4 && date <=19) {value = "Aries";}
if (month == 3 && date > 31) {value = "OK. Whatever.";}
if (month == 4 && date >=20 || month == 5 && date <=20) {value = "Taurus" ;}
if (month == 4 && date > 30) {value = "I'm soooo sorry!";}
if (month == 5 && date >=21 || month == 6 && date <=21) {value = "Gemini";}
if (month == 5 && date > 31) {value = "Umm ... no.";}
if (month == 6 && date >=22 || month == 7 && date <=22) {value = "Cancer";}
if (month == 6 && date > 30) {value = "Sorry .";}
if (month == 7 && date >=23 || month == 8 && date <=22) {value = "Leo";}
if (month == 7 && date > 31) {value = "Excuse me?";}
if (month == 8 && date >=23 || month == 9 && date <=22) {value = "Virgo"; }
if (month == 8 && date > 31) {value = "Yeah. Right.";}
if (month == 9 && date >=23 || month == 10 && date <=22) {value = "Libra";}
if (month == 9 && date > 30) {value = "Try Again.";}
if (month == 10 && date > ;=23 || month == 11 && date <=21) {value = "Scorpio";}
if (month == 10 && date > 31) {value = "Forget it!";}
if (month == 11 && date >=22 || month == 12 && date <=21) {value = "Sagittarius";}
if (month == 11 && date > 30) {value = "Invalid Date";}
if (month == 12 && date >=22 || month == 1 && date <=19) {value = "Capricorn";}
if ( month == 12 && date > 31) {value = "No way!";}
}
