jQuery-显示农历日期，如腊月初八

  • dom结构

<span id="nongli">农历</span>

  • 引用农历方法navCal.js

<script type="text/javascript" src="js/navCal.js"></script>

  • 显示当天的农历日期

$(document).ready(function () {
    //显示农历日期
    var D=new Date();
    var yy=D.getFullYear();
    var mm=D.getMonth()+1;
    var dd=D.getDate();
    if (yy<100) yy="19"+yy;
    $("#nongli").text(GetLunarDay(yy,mm,dd));
});

  • 还可以显示任意一天的农历日期，直接调用方法GetLunarDay(2020,1,1)即可。

  • navCal.js源码如下：

today = new Date();
function initArray() {
    this.length = initArray.arguments.length
    for (var i = 0; i < this.length; i++)
        this[i + 1] = initArray.arguments[i]
}
var d = new initArray(
    "星期日",
    "星期一",
    "星期二",
    "星期三",
    "星期四",
    "星期五",
    "星期六");
// document.write(today.getFullYear(), "年", today.getMonth() + 1, "月", today.getDate(), "日 ", d[today.getDay() + 1], " ");
calendar = new Date();
month = calendar.getMonth();
date = calendar.getDate();
if ((month == 0) && (date == 1)) document.write("元旦");
if ((month == 2) && (date == 12)) document.write("植树节");
if ((month == 3) && (date == 5)) document.write("清明节");
if ((month == 4) && (date == 1)) document.write("国际劳动节");
if ((month == 4) && (date == 4)) document.write("青年节");
if ((month == 5) && (date == 1)) document.write("国际儿童节");
if ((month == 7) && (date == 1)) document.write("建军节");
if ((month == 7) && (date == 16)) document.write("七夕情人节");
if ((month == 9) && (date == 1)) document.write("国庆节/国际音乐节/国际老人节");
if ((month == 11) && (date == 24)) document.write("平安夜");
if ((month == 11) && (date == 25)) document.write("圣诞节");
