This is only relevant for UAs which don't care if forms are usable, which
is most of them.  If forms are expected to work in the first place, then
there needs to be an implicit submit mechanism.  Every browser I'm aware of
has one, and lots of pages depend on this, so it seems like this should be
required somewhere (even if it's conditional upon something like "if user
form entry is supported").

It's a bit of a tortuous route.

The definition of  says:

# The disabled attribute is used to make the control non-interactive and 
# to prevent its value from being submitted.
 - http://www.whatwg.org/specs/web-apps/current-work/#the-input-element

...which links to:

# A form control is disabled if its disabled attribute is set [...]
 - http://www.whatwg.org/specs/web-apps/current-work/#attr-fe-disabled

This is used in the  element section:

# When an input element is disabled, it is immutable.
 - http://www.whatwg.org/specs/web-apps/current-work/#concept-input-immutable

This is then used in the type=submit definition:

# If the element is immutable, it has no activation behavior.
 - 
http://www.whatwg.org/specs/web-apps/current-work/#submit-button-state-(type=submit)

And now the implicit submission section says:

# If the platform supports letting the user submit a form implicitly (for 
# example, on some platforms hitting the "enter" key while a text field is 
# focused implicitly submits the form), then doing so for a form whose 
# default button has a defined activation behavior must cause the user 
# agent to run synthetic click activation steps on that default button.
#
# Consequently, if the default button is disabled, the form is not 
# submitted when such an implicit submission mechanism is used. (A button 
# has no activation behavior when disabled.)

The main difference was that Chrome and Firefox differ in what input types

User agents aren't actually required to let users input anything, so it 
doesn't make much sense to require submission be possible...

What about the situation where there isn't a button?  Implicit

These both trigger the form validation algorithm in Firefox, Opera &

But add a submit button and it does:

I don't think the existence of implicit submit should depend on platform
conventions, though, for interop on forms without visible submit buttons.
 The form implicit submit takes is a platform convention, but it should be
required to exist in some form or another.

Yes. Similarly, some browsers might provide spelling checking, and others 
might not. Some might support tabbing from field to field, others might 
not. The thing is, if a platform does not have the concept of implicit 
submission, presumably the user wouldn't try to implicitly submit anything 
in the first place, so it doesn't matter if the browser does it or not.

This does not contradict what I wrote. It just says what to do if there IS 
an implicit submission mechanism, but there's no button at all.

That's non-conforming currently.

That's not really sensible, but it was technically within the spec's 
language. (You were allowed to not pick a default button if there was one 
to pick from but you didn't like it for some reason.) I've changed the 
spec to make this no longer allowed. The first button will now always be 
the default.

If you submit with one text field and no button, then you are required to 
also submit with two text fields and no button. So this is non-conforming.

Should this be made to for all browser compliance and browser to allow
implicit submission irrespective of visibility of submit button? A web-dev
can always stop this by either disabling the submit button or through
script. Browser can give control back to onsubmit handler on enter key press
if there is enabled submit button.

Reopening discussion -
In case of single Input box and disabled (but visible button) forms still
gets submitted on implicit submission. This is again something weird
and happens in IE & Webkit but not in FF & opera. IMHO, the implicit
submission should have straight away algorithm -

1) If submit button is there but not disabled implicit submission should
happen on enter key press
2) If submit button is there and disabled implicit submission should not
happen on enter key press

Both logic should be irrespective of number of input button OR visibility of
submit button.

In this situation, yes.  Just like as if you called dispatchEvent on it.

Of course you can't trigger click events on such a button using an

I don't find that nice.  As a user, it's very annoying when implicit form
submission doesn't work for some obscure reason (like not having a submit
control), forcing me to use the mouse instead of it behaving like any other
form.  It makes the UI inconsistent and unpredictable.

Also, the single-text-input-with-no-submit-button case doesn't follow the

The "without scripts" is also a fatal caveat.  Users can't be expected to

In principle, *all* forms should allow implicit submit, unless the site

support it.  That ship sailed years ago, but the visibility of the submit

I haven't seen a search engine that requires two text fields by default. And
implicit submission already works on all browsers when there is exactly one
text field.

The current Trident/WebKit behavior has a nice side-effect to (without
scripts) require a visible submit button to enable implicit form submission.

That would have been nice, but there's already interop here: in all four
browsers I tested, two text inputs with no submit button never implicitly
submits.  No browser vendor would change that and break what little
consistency there is, and web compatibility would likely veto it anyway.

See http://zewt.org/~glenn/test-form-submission/table.html, column 4.

But ironing out the bizarre corner cases (eg. columns 7, 8) would be nice,
if compatibility will allow it.

Authors can already do this by injecting script although I'd argue that such

result in form submission.

I personally find implicit form submission to be annoying, and always wished
I could disable it (also backspace triggering backward navigation).

How is that related to the presence or lack of a submit button?  In most
cases there's no correlation.  Where there is one, it's inconsistent,
because authors work around the lack of autosubmit by implementing it
manually; and even when they don't it's still inconsistent, with the strange
dependency on the number of inputs.  (Including hidden ones; because of
this, enabling CSRF form tags in a framework actually changes the UI of
forms.)

It's an authoring question whether the form is one which is submittable, or
one which is, for example, saved automatically on each change, such as some
preference pages.

This is an authoring question, not a user one; either the page's author
intends the form to be submittable or he doesn't.  Having visibility: hidden

Just to add more analysis
Opera - Does Implicit submission in following cases -
* One text field
* One text field with one visible submit button
* One text field with one display:none submit button
* Two text fields with one visible submit button
* Two text fields with one visibility:hidden submit button
* Two text fields with one display:none submit button

Only in following case it does not -
* Two text fields

http://www.w3schools.com/browsers/browsers_stats.asp
Just to consider market shares of browsers - Increasing share of Firefox
(more than 40%) and decreasing share of IE (less than 25%) & also for
Mobiles & Tablets there is Opera Mini which is increasing.

Nothing in "4.10.22.2 Implicit submission" seems to allow implicit
submission to vary based on whether a submit button is displayed or not...

(It also explicitly says that if implicit submit is supported but there's no
submit button in the form, the implicit submit must still happen.  That
doesn't sound like it could be followed, since lots of pages are probably
depending on the absence of a submit button suppressing implicit submit.
That's just backwards-compatibility, not platform conventions, though.)

I had to make it run without data: to work around IE9.  These were run in

Re: [whatwg] HTMLForms: Implicit Submission with {display:none} button

2011-09-24 Thread Ryosuke Niwa
FYI, I checked Firefox 5's & Internet Explorer 9's behaviors as well.

IE9 does implicit submission in the following conditions:

   - One text field
   - One text field with one visible submit button
   - One text field with one display:none submit button
   - Two text fields with one visible submit button

It does not do implicit submissio in the following conditions:

   - Two text fields
   - Two text fields with one visibility:hidden submit button
   - Two text fields with one display:none submit button

Basically, IE9 only does implicit submission when there is exactly one text
field (you can have checkbox, hidden, etc...) or there is a visible button
(i.e. not diplay: none nor visibility: hidden).

Firefox 5 does implicit submission in the following conditions:

   - One text field
   - One text field with one visible submit button
   - One text field with one display:none submit button
   - Two text fields with one visible submit button
   - Two text fields with one visibility:hidden submit button
   - Two text fields with one display:none submit button

It does not do implicit submissio in the following conditions:

   - Two text fields

In summary, Firefox special cases one text field (can have checkbox, hidden,
etc...) like MSIE and requires a submit button with more than two text
fields regardless of presence of visibility: hidden or display: none.

WebKit's behavior is very confusing here. It does implicit submission in the
following conditions:

   - One text fields
   - Two text fields
   - One text field with one visible submit button
   - Two text fields with one visible submit button
   - Two text fields with one visibility:hidden submit button
   - One text field with one display:none submit button

However, it doesn't submit when we have:

   - Two text fields with one display:none submit button

Given that WebKit implicitly submits form even in the presence of a visible
submit button or an invisible submit button (visibility: hidden, or display:
none with exactly one text field), I don't see why we should avoid implicit
submission only when there are multiple form controls and a display:none
submit button.

The strict answer is that it's up to the browsers; the spec allows 
browsers to do whatever they think is appropriate per their platform's 
conventions. So both behaviours are compliant.

The guidelines in the spec do not say anything about the behaviour being 
different for elements that are display:none or otherwise hidden, though, 
so I don't see any reason to consider the visibility of a button in making 
the decision as to which button is the default.

[whatwg] HTMLForms: Implicit Submission with {display:none} button

2011-09-23 Thread Kaustubh Atrawalkar
Hi,
There is an issue regarding form submit button which is little unclear from
the specs mentioned in here http://www.whatwg.org/specs/web-apps/cu ...
submission
If the form has submit button with display property as none, will that form
should be implicitly submitted on pressing enter key? This works in Opera &
Firefox but does not work in IE & Safari as of now. What is the expected
behavior for this?

Thanks & Regards
