做得比较急，所以没考虑兼容性。
通过两个类实现，一个是面板类，一个是日历类。
由于我开发时所有公共js都是在顶级窗口一次加载的，所以在子窗口创建对象时需要把当前窗口对象传进去，例如： var panel = new parent.parent.SelectPanel(self);如果没传self参数，默认就是加载js的窗口。

marcian 在网上找的那个公历算法有点复杂，呵呵。我获取当前月最大天数，以及当前月第一天是星期几是直接通过JS自带的Date函数来实现的。
代码如下:
// 获取当月最大天数
//asfman提供更简单的方式：return (new Date(y, m+1, 0)).getDate()
function GetDates(year, month)
{
var date = new Date(year, month, 31);
return 31 - date.getDate() || 31;
}
// 获取当月第一天是星期几
function GetFirstDay(year, month)
{
return (new Date(year, month, 1)).getDay();
}

/* 下面这部分可以不要，因为即使出现new Date(2007, -1, 31)，这种现象，Date会自动转换成Date(2006, 12, 31)
if(month < 0)
{
month = 11;
year--;
}
if(month == 12)
{
month = 0;
year++;
}*/
