本文实例讲述了JS简单获取当前日期和农历日期的方法。分享给大家供大家参考,具体如下:

navCal.js文件如下:

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");

}
showCal();

调用方法:

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

运行效果图如下:
