JS日期和时间选择控件
Calendar.js（注：在.net环境下.js文件需存为utf
-
8格式）
/**/
/**
*本日历选择控件由tiannet根据前人经验完善而得。大部分代码来自meizz的日历控件。 *tiannet添加了时间选择功能、select,object标签隐藏功能，还有其它小功能。 *使用方法： * (1)只选择日期 <input type="text" name="date" readOnly onClick="setDay(this);"> * (2)选择日期和小时 <input type="text" name="dateh" readOnly onClick="setDayH(this);"> * (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);"> *设置参数的方法 * (1)设置日期分隔符 setDateSplit(strSplit);默认为"-" * (2)设置日期与时间之间的分隔符 setDateTimeSplit(strSplit);默认为" " * (3)设置时间分隔符 setTimeSplit(strSplit);默认为":" * (4)设置(1),(2),(3)中的分隔符 setSplit(strDateSplit,strDateTimeSplit,strTimeSplit); * (5)设置开始和结束年份 setYearPeriod(intDateBeg,intDateEnd) *说明： * 默认返回的日期时间格式如同：2005-02-02 08:08
