这篇文章主要介绍了Js中显示日期和农历的代码，很简单，但很实用，有图片，需要的朋友可以参考下

1.显示日期代码：

Js代码

/*获取当前日期*/

function getCurrentDateTime() {

var d = new Date();

var year = d.getFullYear();

var month = d.getMonth() + 1;

var date = d.getDate();

var week = d.getDay();

/*时分秒*/

/*var hours = d.getHours();

var minutes = d.getMinutes();

var seconds = d.getSeconds();

var ms = d.getMilliseconds();*/

var curDateTime = year;

if (month > 9)

curDateTime = curDateTime + "年" + month;

else

curDateTime = curDateTime + "年0" + month;

if (date > 9)

curDateTime = curDateTime + "月" + date + "日";

else

curDateTime = curDateTime + "月0" + date + "日";

/*if (hours > 9)

curDateTime = curDateTime + " " + hours;

else

curDateTime = curDateTime + " 0" + hours;

if (minutes > 9)

curDateTime = curDateTime + ":" + minutes;

else

curDateTime = curDateTime + ":0" + minutes;

if (seconds > 9)

curDateTime = curDateTime + ":" + seconds;

else

curDateTime = curDateTime + ":0" + seconds;*/

var weekday = "";

if (week == 0)

weekday = "星期日";

else if (week == 1)

weekday = "星期一";

else if (week == 2)

weekday = "星期二";

else if (week == 3)

weekday = "星期三";

else if (week == 4)

weekday = "星期四";

else if (week == 5)

weekday = "星期五";

else if (week == 6)

weekday = "星期六";

curDateTime = curDateTime + " " + weekday;

return curDateTime;

}

2.显示农历代码：

Js代码

/*获取当前农历*/

function showCal(){

var D=new Date();

var yy=D.getFullYear();

var mm=D.getMonth()+1;

var dd=D.getDate();

var ww=D.getDay();

var ss=parseInt(D.getTime() / 1000);

if (yy<100) yy="19"+yy;

return GetLunarDay(yy,mm,dd);

}

//定义全局变量

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,0x2192B,0xA95,0x71695,0x6CA,0xB55,0x50AB5,0x4DA,0xA5B,0x30A57,0x52B,0x8152A,0xE95,0x6AA,0x615AA,0xAB5,0x4B6,0x414AE,0xA57,0x526,0x31D26,0xD95,0x70B55,0x56A,0x96D,0x5095D,0x4AD,0xA4D,0x41A4D,0xD25,0x81AA5,0xB54,0xB6A,0x612DA,0x95B,0x49B,0x41497,0xA4B,0xA164B, 0x6A5,0x6D4,0x615B4,0xAB6,0x957,0x5092F,0x497,0x64B, 0x30D4A,0xEA5,0x80D65,0x5AC,0xAB6,0x5126D,0x92E,0xC96,0x41A95,0xD4A,0xDA5,0x20B55,0x56A,0x7155B,0x25D,0x92D,0x5192B,0xA95,0xB4A,0x416AA,0xAD5,0x90AB5,0x4BA,0xA5B, 0x60A57,0x52B,0xA93,0x40E95);

}

}

}

}

function GetcDateString(){

/*显示农历年：( 如：甲午(马)年 )*/

/*tmp+=tgString.charAt((cYear-4)%10);

}else{

}

tmp+="月";

}

function GetLunarDay(solarYear,solarMonth,solarDay){

return "";

}else{

}

}

3.显示：

Js代码

$(function(){

var date = getCurrentDateTime();

var calendar = showCal();

$("#currentDate").text("今天是: " + date + "农历：" + calendar);

});
