显示阴历（农历）日期的js代码

有时我们在网页设计中常常会用到显示阴历（农历）日期，这时可能很多人会想到通过复杂的程序来实现，其实我们完全可以通过JS代码来实现，下面的JS代码就是可以实现显示阴历（农历）日期，你可以把下面的代码复制保存为JS在网页当中调用就可以了，代码如下：

function RunGLNL(){
var today=new Date();
var d=new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
var DDDD=(today.getYear()<100 ?
today.getYear()+1900:today.getYear())+"年"+(today.getMonth()+1)+"月"+today.getDate()+"日";
DDDD = DDDD + " " + d[today.getDay()];
DDDD = DDDD+ " " + (CnDateofDateStr(today));
//DDDD = DDDD+ " " + SolarTerm(today);
document.write(DDDD);
}
