第一步：做个 文本框用于显示年月日的
第二步：点击文本框触发
var month=date.getMonth()+1;
month =(month<10 ? "0"+month:month);
var mydate = (year.toString()+month.toString());
注意，year.toString()+month.toString()不能写成year+month。不然如果月份大于等于10，则月份为数字，会和年份相加，如201210，则会变为2022，需要加.toString()
以下是搜到的有用内容：
var myDate = new Date();
myDate.getYear(); //获取当前年份(2位)
myDate.getFullYear(); //获取完整的年份(4位,1970-????)
myDate.getMonth(); //获取当前月份(0-11,0代表1月)
myDate.getDate(); //获取当前日(1-31)
myDate.getDay(); //获取当前星期X(0-6,0代表星期天)
myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)
myDate.getHours(); //获取当前小时数(0-23)
myDate.getMinutes(); //获取当前分钟数(0-59)
myDate.getSeconds(); //获取当前秒数(0-59)
myDate.getMilliseconds(); //获取当前毫秒数(0-999)
myDate.toLocaleDateString(); //获取当前日期
var mytime=myDate.toLocaleTimeString(); //获取当前时间
myDate.toLocaleString( ); //获取日期与时间
<SCRIPT LANGUAGE="JavaScript">
function monthnow(){
var now = new Date();
var monthn = now.getMonth();
var yearn = now.getYear();
window.location.href="winnNamelist.jsp?getMonth="+monthn+"&getYear="+yearn;
}
