Q1: 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。
