js获取农历
上⼀篇我们对upupoo⽹页壁纸改造时⽤到了农历，，这⾥记⼀下笔记：
获取当前农历的js
主js:
//农历
var CalendarData=new Array(100);
var madd=new Array(12);
var tgString="甲⼄丙丁戊⼰庚⾟壬癸";
var dzString="⼦丑寅卯⾠巳午未申⾣戌亥";
var numString="⼀⼆三四五六七⼋九⼗";
var monString="正⼆三四五六七⼋九⼗冬腊";
var weekString="⽇⼀⼆三四五六";
var sx="⿏⽜虎兔龙蛇马⽺猴鸡狗猪";
var cYear,cMonth,cDay,TheDate;
CalendarData = new Array(0xA4B,0x5164B,0x6A5,0x6D4,0x415B5,0x2B6,0x957,0x2092F,0x497,0x60C96,0xD4A,0xEA5,0x50DA9,0x5AD,0x2B6,0x3126E, 0x92E,0x7192D,0xC95,0xD4A,0x61B4A,0xB55,0x56A,0x4155B, 0x25D,0x92D,0            madd[0]=0;
madd[1]=31;
madd[2]=59;
madd[3]=90;
madd[4]=120;
madd[5]=151;
madd[6]=181;
madd[7]=212;
madd[8]=243;
madd[9]=273;
madd[10]=304;
madd[11]=334;
function GetBit(m,n){
return (m>>n)&1;
}
function e2c(){
TheDate= (arguments.length!=3) ? new Date() : new Date(arguments[0],arguments[1],arguments[2]);
var total,m,n,k;
var isEnd=false;
var Year();
if(tmp<1900){
tmp+=1900;
}
total=(tmp-1921)*365+Math.floor((tmp-1921)/4)+Month()]+Date()-38;
Year()%4==0&&Month()>1) {
total++;
}
for(m=0;;m++){
k=(CalendarData[m]<0xfff)?11:12;
for(n=k;n>=0;n--){
if(total<=29+GetBit(CalendarData[m],n)){
isEnd=true; break;
}
total=total-29-GetBit(CalendarData[m],n);
}
if(isEnd) break;
}
cYear=1921 + m;
cMonth=k-n+1;
cDay=total;
if(k==12){
if(cMonth==Math.floor(CalendarData[m]/0x10000)+1){
cMonth=1-cMonth;
}
if(cMonth>Math.floor(CalendarData[m]/0x10000)+1){
cMonth--;
}
}
}
function GetcDateString(){
var tmp="";
js arguments
tmp+=tgString.charAt((cYear-4)%10);
tmp+=dzString.charAt((cYear-4)%12);
tmp+="(";
tmp+=sx.charAt((cYear-4)%12);
tmp+=")年 ";
if(cMonth<1){
tmp+="(闰)";
tmp+=monString.charAt(-cMonth-1);
}else{
tmp+=monString.charAt(cMonth-1);
}
tmp+="⽉";
tmp+=(cDay<11)?"初":((cDay<20)?"⼗":((cDay<30)?"廿":"三⼗"));
if (cDay%10!=0||cDay==10){
tmp+=numString.charAt((cDay-1)%10);
}
return tmp;
}
function GetLunarDay(solarYear,solarMonth,solarDay){
//solarYear = solarYear<1900?(1900+solarYear):solarYear;
if(solarYear<1921 || solarYear>2020){
return "";
}else{
solarMonth = (parseInt(solarMonth)>0) ? (solarMonth-1) : 11;
e2c(solarYear,solarMonth,solarDay);
return GetcDateString();
}
}
使⽤：
//农历
var FullYear();
var Month()+1;
var Date();
if (yy<100) yy="19"+yy;
