強大的JS日期/時間選擇控件（精確到天、小時、分鐘都可以）

<script language="JavaScript"> 
/**//** 
*本日歷選擇控件由tiannet根據前人經驗完善而得。大部分代碼來自meizz的日歷控件。 
*tiannet添加了時間選擇功能、select,object標簽隱藏功能，還有其它小功能。 
*使用方法： 
* (1)只選擇日期 <input type="text" name="date" readOnly onClick="setDay(this);"> 
* (2)選擇日期和小時 <input type="text" name="dateh" readOnly onClick="setDayH(this);"> 
* (3)選擇日期和小時及分鐘 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">
 *設置參數的方法 
* (1)設置日期分隔符 setDateSplit(strSplit);默認為"-" 
* (2)設置日期與時間之間的分隔符 setDateTimeSplit(strSplit);默認為" " 
* (3)設置時間分隔符 setTimeSplit(strSplit);默認為":" 
* (4)設置(1),(2),(3)中的分隔符 setSplit(strDateSplit,strDateTimeSplit,strTimeSplit); 
* (5)設置開始和結束年份 setYearPeriod(intDateBeg,intDateEnd) 
*說明： 
* 默認返回的日期時間格式如同：2005-02-02 08:08
