null or not a object
I have this javascript code:
Code:
function shodt(flpth,pth,pth1,infld,crdate,seldate,fld) //to display the date window
{
if(fld=="retdt")
{
if(document.fexp.depdt.value!="")
{
document.fexp.retdt.value="";
document.fexp.retdt1.value="";
glbdate="true";
checkdate(flpth,pth,pth1,infld,crdate,seldate,fld)
}
}
else if(fld=="depdt")
{
if(document.fexp.depdt.value=="")
{
document.fexp.seldate.value="";
document.fexp.depdt1.value="";
seldate="";
}
glbdate="true";
checkdate(flpth,pth,pth1,infld,crdate,seldate,fld)
}
}
with this image i am sending these parameters to the function:
Code:
<img src="asp/images/hd_icon_calender.gif" align="middle" alt="Calendar" width="21" height="15" border="0" onClick="shodt('calendar.html','document.fexp.depDay.value','document.fexp.depMonth.value','document.fexp.crdate.value','document.fexp.seldate.value','depDay','depDay')">
i get the errror:
document.fexp.retdt.value is null or not a object.

Is there an object with an id of retdt in your page? E.g. something like:
<someTag id="retdt" someAttributes="someValue" />
If so, what kind of object / tag is it?

To reference something like document.fexp.retdt.value you need a <form> with an name of fexp and a control (like a textbox, dropdown etc) with a name of retdt.
If you don't have this form and control, document.fexp.retdt.value results in a null pointer exception.
Cheers,
Imar
