java漂亮日历源代码 java编写日历代码

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！！！

!--日期框选择--

var DS_x,DS_y;

function dateSelector() //构造dateSelector对象，用来实现一个日历形式的日期输入框。

{

var myDate=new Date();

this.year=myDate.getFullYear(); //定义year属性，年份，默认值为当前系统年份。

this.month=myDate.getMonth()+1; //定义month属性，月份，默认值为当前系统月份。

this.date=myDate.getDate(); //定义date属性，日，默认值为当前系统的日。

this.inputName=''; //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！

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

}

function display() //定义dateSelector的display方法，它将实现一个日历形式的日期选择框。

* 1. 将容器由Frame改为了Dialog，以便在基于对话框的程序中也能够使用

* 2. 将最小日期由1980改为了1950，考虑到目前球员的出生日期可能早于1980年

* 3. 将初始显示格式设置为 yyyy年MM月dd日 格式，原有的小时去掉了，不适合于出生日期字段
