但是也有些问题，第一画日历有点慢，第二兼容性不太好IE Only，第三它不是基于jQuery的哈哈。
那还是老规矩，做之前先看下效果
这下是更酷的Ext风格了。
从上图我们可以看出这个控件其实有两个视图一个日期月视图，还有一个是年月选择视图。
1：还是先从HTML入手
日期控件确定HTML其实还是比较简单，因为明摆着是列表的数据格式，当然主要是采用table了。
两个视图分别用两个Div包裹，控制div的显示隐藏即可以切换视图了。完整的HTMl结构大家可以用IEDeveloper看一下Demo的结构，我自己截了一个图 
2：根据HTML和效果图编写CSS
其实因为是Ext风格的，所以直接copy的ext的css和图片。。
CSS也就不分析了，直接上代码。
因为博客园的语法高亮不支持CSS，所以就不贴出来了，给个下载地址吧：
所有用到的图片：
3：搞定了CSS之后呢，就开始编写我们javascript了。
上来就是一个完整代码
复制代码 代码如下:

首先还是套版化编写jQuery控件的套子:
