求Java万年历源代码!!!

我有个JS的要么？

你可以把他改下我是没时间帮你该哈！！！

thisinputName=''; //定义inputName属性，即输入框的name，默认值为空。注意：在同一页中出现多个日期输入框，不能有重复的name！

thisdisplay=display; //定义display方法，用来显示日期输入框。

java获取一个时间的年月日代码及相关解释说明参考下面代码

package zhidao;

import javautilCalendar;

public class Test {

 public static void main(String[] args) {

  Calendar cal=CalendargetInstance();//使用日历类

  int year=calget(CalendarYEAR);//获取年份

  int month=calget(CalendarMONTH)+1;//获取月份，因为从0开始的，所以要加1

  int day=calget(CalendarDAY_OF_MONTH);//获取天

  Systemoutprintln("结果："+year+"-"+month+"-"+day);

 }

}

记事本代码这里已经贴不上了。你百度HI我，我给你。

1、使用new Date()获取当前日期，new Date()getTime()获取当前毫秒数

2、计算公式，等于获取的当前日期减去或者加上一天的毫秒数。一天的毫秒数的计算公式：24小时60分钟60秒1000毫秒，也是86400000毫秒。

举例：

Date curDate = new Date();

var preDate = new Date(curDategetTime() - 2460601000); //前一天

var nextDate = new Date(curDategetTime() + 2460601000); //后一天

以下使用后台输出表示。

扩展资料

var myDate = new Date();

myDategetYear();        //获取当前年份(2位)

myDategetFullYear();    //获取完整的年份(4位,1970-)

myDategetMonth();       //获取当前月份(0-11,0代表1月)

myDategetDate();        //获取当前日(1-31)

myDategetDay();         //获取当前星期X(0-6,0代表星期天)

myDategetTime();        //获取当前时间(从197011开始的毫秒数)

myDategetHours();       //获取当前小时数(0-23)

myDategetMinutes();     //获取当前分钟数(0-59)

myDategetSeconds();     //获取当前秒数(0-59)

myDategetMilliseconds();    //获取当前毫秒数(0-999)

myDatetoLocaleDateString();     //获取当前日期

var mytime=myDatetoLocaleTimeString();     //获取当前时间

myDatetoLocaleString( );        //获取日期与时间

DateprototypeisLeapYear 判断闰年

DateprototypeFormat 日期格式化

DateprototypeDateAdd 日期计算

DateprototypeDateDiff 比较日期差

DateprototypetoString 日期转字符串

DateprototypetoArray 日期分割为数组

DateprototypeDatePart 取日期的部分信息

DateprototypeMaxDayOfDate 取日期所在月的最大天数

DateprototypeWeekNumOfYear 判断日期所在年的第几周

StringToDate 字符串转日期型

IsValidDate 验证日期有效性

CheckDateTime 完整日期时间检查

daysBetween 日期天数差
