Checkbox not readable by wf:q/1
Reported by Rusty Klophaus | April 28th, 2010 @ 07:54 AM | in 2.0.1
From Fabian Król on the newsgroup:
I have simple code:
content() ->
[
#flash {},
#checkbox {id=chb1, checked=true},
#checkbox {id=chb2},
#button { postback=accept }
].
event(accept) ->
Chb1 = wf:q(chb1),
Chb2 = wf:q(chb2),
wf:flash(wf:f("~s ~s", [Chb1, Chb2])).
The behavior i would expect is to get information about
checked/not
checked but i always receive value "on". It doesn't say anything
about
the state of checkbox.
Of course i can remember the state in other place and react
with
postback in checkbox object but it seems to by ugly ;)

I've posted a fix for this, as well as added support for the "value" attribute on the checkbox field.
http://github.com/choptastic/nitrogen/commit/dce295e82d917310b2fde5...
Assuming the following checkboxes
[ #checkbox{id=fruit,value="apple",text="Apple"}, #checkbox{id=fruit,value="orange",text="Orange",checked=true}, #checkbox{id=fruit,value="banana",text="Banana",checked=true} ].
wf:qs(fruit) would yield ["orange","banana"]
This, to me, seems the appropriate way to handle checkboxes to stay consistent with HTML form submission.
