顯示今天的日期js程式碼(陽曆和農曆)_javascript技巧

1.顯示日期代碼：

Js代碼

/*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.顯示農曆代碼：

Js代碼

/*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);

Js代碼

$(function(){ 
var date = getCurrentDateTime(); 
var calendar = showCal(); 
$("#currentDate").text("今天是: " + date + "农历：" + calendar); 
});
