IF you can/want to change the cfform.js, thhe fix I did also works,
without having to check for a space, or add a space ass the value for
the first option ...
cfform.js ORIGINAL ...
else if (obj_type == "SELECT")
{
for (i=0; i < obj.length; i++)
{
if (obj.options[i].selected)
return true;
}
return false;
}
What I changed it to (only a few extra lines) ...
else if (obj_type == "SELECT")
{
if(obj.multiple) {
StartFrom=0;
}
else {
StartFrom=1;
}
for (i=StartFrom; i < obj.length; i++)
{
if (obj.options[i].selected)
return true;
}
return false;
}

Here's a solution to making the CFSELECT work as you want,
Andrew.
First, let me say that I know that many hate any of the CFFORM
tags, but
I'll clarify that for some uses (like CFSELECT in particular),
it's not too
bad (dynamically generating select options, doing the JS
validation).
That said, this issue you raise about using REQUIRED on a single
SELECT is
indeed one that MM/Adobe seems to have thought about. According
to the CFMX
7 docs, you should be able to work-around this. I quote:
You can work around this issue: format forms by having
an initial
option tag with value=" " (note the space character between the
quotation
marks).
This was from:
http://livedocs.macromedia.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/comm
on/h
tml/wwhelp.htm?context=ColdFusion_Documentation&file=part_cfm.htm
I've tested it, though, and it's not doing what it would suggest
it should.
Here's an example:
<cfform>
<cfselect name="test" required="Yes">
<option value=" ">select an option
<option>1
<option>2
</cfselect>
<input type="Submit">
</cfform>
Note that as of CFMX, you no longer need to bother with a NAME
or ACTION for
CFFORM, and like a regular <FORM>, if you leave off the ACTION
it posts to
itself. If you add SIZE="2" and submit it without selecting an
item, you get
the expected validation for not choosing something, so it's not
that there's
anything wrong with the code above.
It just doesn't seem that their proposed "workaround" really
works. I looked
at the code in /CFIDE/scripts/cfform.js, which holds the
_CF_hasValue
function that is called for the validation, and it just doesn't
honor this
"workaround":
else if (obj_type == "SELECT")
{
for (i=0; i < obj.length; i++)
{
if (obj.options[i].selected)
return true;
}
return false;
If you change it to this, though, it seems to do the trick:
else if (obj_type == "SELECT")
{
for (i=0; i < obj.length; i++)
{
if (obj.options[i].selected)
{
if (obj.options[i].value == " ")
return false;
else
return true;
}
}
return false;
}
The question, then, is whether you want to change this JS file
that CFFORM
relies on (or even have the security access to do it). I could
see it
negatively affecting code where someone intentionally left a
VALUE as " "
and meant for that to be passed through. It would seem that a
better
solution would be to add an attribute for CFSELECT that enables
this
"workaround" behavior more intentionally.
I'll write a blog entry about this and also point to it in the
livedocs.
Maybe Adobe can address it in the future. Could be a nice bone
for BD to
add. :-)

I have had the same problem (on 6.1 anyways), was so annoying
because I HAD
to use CFFORM (wasn't allowed to re-do it as a normal FORM), and
HAD to have
a first option the same as you (like "Select Whatever"). Having
REQUIRED="Yes" is completely useless in a CFSELECT if it is a
single SELECT
list (or a multiple SELECT with SIZE=1). I had to fix it by
editing CF's
cfform.js that sits in the CFIDE/scripts directory (which you
might not
want/be able to do) to do a simple check to see if the SELECT
list to check
was multiple or single ... if(obj.multiple) ... if it's a single
SELECT
list, then I made it fail if option 0 was selected.

Am fixing up someone else's code, and they have a
cfselect in there
that is set required="yes", which doesn't work at all, in that
the first
option in the select list, which is along the lines of "Please
select an
option", still passes the required check (which it shouldn't).
I haven't used cfform much myself, so is this correct ? If it
is, then that
is pretty useless, isn't it ?
