以下这个JS日历控件是我的闲暇之余自己编写的，所有的代码全部在IE7/IE8/Firefox下面测试通过，
而且可以解决被iframe层遮盖的问题。现在只提供两种风格（简洁版和古典版）和两种语言（英文和中文）。支持自定义日期格式，设定时间范围。
默认为古典版，英文，下面来看简单的缩略图。
首先是简洁版：
日期选择器：
月份选择器：
然后是古典版：
日期选择器：
日期选择器中文语言
月份选择器
下面是使用方法：
在要使用这个控件的页面上引入这个JS
<script type="text/javascript" src="javascript/DatePicker.js"></script>
使用月份选择器，默认时间格式为yyyy-MM
<input id="begintime" type="text" onclick="setmonth(this)" readonly="readonly" />
使用日期选择器，默认时间格式为yyyy-MM-dd
<input id="endtime" type="text" onfocus="setday(this)" readonly="readonly" />
使用日期选择器，一共提供五个参数，其中第一个参数是Object类型，指需要填入日期的元素对象；第二个参数是时间的格式，默认为yyyy-MM-dd；第三、四个参数分别为开始时间和结束时间；第五个参数是语言种类，这个1表示中文，0为英文（默认采用英文）
<input id="endtime" type="text" onfocus="setday(this,'yyyy-MM-dd','2010-01-01','2010-12-30',1)" readonly="readonly" />
风格默认使用古典版，如果需要使用简洁版，则进入代码中
将上述代码中的上部分代码（38行-63行）注释，在把他换成下面部分的代码（67行-90行）。则风格就可以改为简洁版了。
说了这么多，下面附上这个日历控件的JS文件：
