使用的时候注意，formName形如document.search,M=0时为阳历到阴历，
M=1时为阴历到阳历，另外注意，客户端年月日应该这样写：
农历日期：
<input type=text name=nyear> 年
<input type=text name=nmonth> 月
<input name=nday type=text> 日
输入阳历日期：
<input type=text name=yyear> 年
<input type=text name=ymonth> 月
<input type=text name=yday> 日
这样才能确保能正常使用，同时该函数计算出了该年度是什么年
等俺有了时间就转为java版的
//农历日期
var nDate;
//阳历日期
var yDate;
//计算某一年是什么年,注意是按照农历计算的
var animal;
function getNDate(){
return nDate;
}
function getYDate(){
return yDate;
}
function getAnimal(){
return animal;
}
function CalConv(formName,M)
