*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
