Javascript 日期 时间 选择控件

/**
  2 *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。
  3 *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。
  4 *使用方法：
  5 * (1)只选择日期   <input type="text" name="date"   readOnly onClick="setDay(this);">
  6 * (2)选择日期和小时  <input type="text" name="dateh"  readOnly onClick="setDayH(this);">
  7 * (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">
  8 *设置参数的方法
  9 * (1)设置日期分隔符    setDateSplit(strSplit);默认为"-"
 10 * (2)设置日期与时间之间的分隔符  setDateTimeSplit(strSplit);默认为" "
 11 * (3)设置时间分隔符    setTimeSplit(strSplit);默认为":"
 12 * (4)设置(1),(2),(3)中的分隔符  setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);
 13 * (5)设置开始和结束年份    setYearPeriod(intDateBeg,intDateEnd)
 14 *说明：
 15 * 默认返回的日期时间格式如同：2005-02-02 08:08
