一个在时间选择上很有用的代码

来源：互联网发布：vb可不可以治耳螨编辑：程序博客网时间：2024/04/25 06:09

最近公司在做一个系统，要用一个时间选择控件，本来是用ASP。NET来做，但最后我就用JS来写

具体代码（部分）：
TIME.JS
--------------------------------------

//请大家保证版本的完整性
function fTime(iHour,iSec,iMin)
{
return iHour+iSec+iMin;
}
//当前日期
//<input type="text" size="10" name="datBegin" value="<%=formatdatetime(dateandtime_start,2)%>" maxlength="10"   readonly onclick="fPopCalendar(datBegin,datBegin);return false">日<%h_time(int(hour(dateandtime_start))),23,"datHourBegin"%>时<%h_time(int(minute(dateandtime_start))),59,"datMinuteBegin"%>分(日期格式:yyyy-mm-dd)
function getNowDate()
{
   var nn=new Date();
   year1=nn.getYear();
   mon1=nn.getMonth()+1;
   date1=nn.getDate();

   var datestr1
   if(mon1<10)
    monstr1="0"+mon1;
   else

{

   date1=nn.getDate();
