getting checkbox to pass value when unchecked

[ggallen]

I really don't think this can be done but...

I have a list of checkboxs, and when I submit the form
only those boxs that are "checked" will be returned
to my .cgi script with the value set.

Is there anyway to to have an alternate value returned.


....wait.... idea just hit just have to test it.

I'm thinking prior to submitting, I scan the elements for
the checkboxes I want. If they are unchecked, then check
them, but then change their value, so my .cgi can check
for the changed value.

so... my HTML would read

<INPUT TYPE="CHECKBOX" NAME="BOXX" VALUE="YES">

my javascript will set the .checked to true, then
set the .value to "NO"

otherwise the value will be "YES"


Or is there an HTML way to set an unchecked value?

Your idea will work unless the user happens to have JavaScript disabled. Why not just change the server side code to handle the non-presense of unchecked items?

[ggallen]

I can't. Since some of the other functions of the page
will determine which check boxes are on the form to
start with. They are dynamically created, so I never
know which check boxs were there prior to the page
creation.

in this case, javascript won't be disabled. It's a LAN thing,
and if javascript is disabled, nothing will work.
Just as only IE is used, which makes coding a bit easier as well
(not because it's IE, but I don't need to do x-browser checking)

If you add some additional "hidden" form fields to clue the next page in as to what should be present you can still avoid developing the javascript.

[ggallen]

yea...I could....but there could a hundred or so checkboxes,
so the hidden field's value could grow to to quite a length.
I'm already passing a lot of data back and forth, I'd rather
not add to it. Since the majority of the boxes will be checked
I'd rather not add a thousand bytes to check if one box
is unchecked.
