一個在時間選擇上很有用的代碼

最近公司在做一個系統,要用一個時間選擇控制項,本來是用ASP。NET來做,但最後我就用JS來寫

具體代碼(部分):
TIME.JS
--------------------------------------

//請大家保證版本的完整性
function fTime(iHour,iSec,iMin)
{
 return iHour+iSec+iMin;
}
//當前日期
//<input type="text" size="10" name="datBegin" value="<%=formatdatetime(dateandtime_start,2)%>" maxlength="10"   readonly  >日<%h_time(int(hour(dateandtime_start))),23,"datHourBegin"%>時<%h_time(int(minute(dateandtime_start))),59,"datMinuteBegin"%>分(日期格式:yyyy-mm-dd)
