javascript 日历提醒系统( 兼容所有浏览器 )

功能介绍：
1.正常的日历功能。
2.等等等
3.接收 数组
例如：

new Calendar("id").show( 
{ 
"20091120": "今天干了嘛嘛。。。", 
"2009320": "今天干了嘛嘛。。。" 
} 
);

日历提示样式分为3类。
a. 当日
b.当年当月当日提示样式
c.当月当日提示样式
鼠标覆盖在有提示的日期上自动出现提示内容
4.。。。。。
主要分为2种用处。
1.提供一个 div 或其他 element 将该容器的 id 传给 Calendar。方法名为: show()
例: var cr = Calendar("div1");
cr.show( /*data - 该数组为可选项，如果传则有提示功能*/ );
2.提供一个 input[type='text'] 的元素 将该元素的 id 传给 Calendar。方法名为: pop()
例: var cr = Calendar("input2");
cr.pop();
其他的就不多说了。觉得好的话，就支持下。呵呵。
有什么问题或好的想法，请告诉我。谢谢
详细的用法和例子在压缩包里有。
