显示今天的日期js代码(阳历和农历)

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;

3.显示：

Js代码

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