收集几个js实现的日期时间控件

/**//**
 *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

时间：2004-01-01
作者：Smart
功能：日历式日期选择控件
 
参数：
说明：
1.输入框直接调用用以下代码
<Script>DateBox("InputName","DateValue")<\/Script>
其中:InputName 为输入日期的文本框.注:不能为空.
       DateValue  为输入日期的文本框默认日期值.格式为:YYYY-MM-DD.如2004-01-01
                       此值可以不填或为空.则默认值为当天日期.(客户端)
2.其它"按钮"调用用以下代码
CallDate("InputName")
其中:InputName 为输入日期的文本框.注:不能为空.
