Other properties, please debug yourself. The disadvantage of this date processing function is that day is not associated with month, and it is better to use JS processing

One of the functions that JS displays day can be defined as follows:

function Showdays (year,month) {
var day= "Day";
if (month.value==0) {
 document.getElementById (day). Length=1;
 return;
} else{
 if (month.value==1| | month.value==3| | month.value==5| | month.value==7| | month.value==8| |month.value==10| | month.value==12) {
   document.getElementById (day). Length=1;
   CreateList (1,32,day);
   return;
 } else if (month.value==2) {
 if (year.value%4==0&&year.value%100!=0| | year.value%400==0) {
  document.getElementById (day). Length=1;
  CreateList (1,30,day);
  return;
 } else{
  document.getElementById (day) length=1;
  CreateList (1,29,day);
  return;
 }
 else{
 document.getElementById (day) length=1;
 CreateList (1,31,day);
 return;}}
