Bug 23588 – Add inputmode attribute support, as per XHTML Basic 1.1

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: DOM

[Adam Treat]

inputmode attribute support should be added to comply with:

http://www.w3.org/2008/06/mobile-test/

The attribute is defined and specified here:

http://www.w3.org/TR/xhtml-basic

Patch from George to implement

Implements the basic skeleton for inputmode support.  The UI elements come next.

Patch from George to implement

I'd be interested to hear more about what the rest of the support would look like.  Just adding this js accessor (especially if just to pass http://www.w3.org/2008/06/mobile-test/) seems silly.  Adding real inputmethod= support seems interesting, but I'm not sure what that support would look like.  Maybe you can tell me more?

[George Staikos]

We plan to implement all of the rest in our application.

[George Staikos]

Any reviewer?

Patch from George to implement

I don't think it is appropriate to unconditionally include this attribute as it will make feature detection incorrect for embedders who do not implement this functionality or do not want to.  That said, I am not sure what the correct #define would be.

ENABLE(INPUTMODE)?

patch for XHTML Basic 1.1

This patch is to add the XHTML Basic 1.1 support (conditionally with ENABLE_XHTMLBASIC), specifically, inputmethod support.

Attribute "inputmethod" for "input" and "textarea" element servers as a input method hint, so that we the control is in focus, the system automatically switchs to the input method indicated by "inputmethod" attribute.

This applies to most mobile devices which have limited input hardware, and need to switch between input methods to take advantage of limited hardware input capabilities.  The inputmode helps to facilitate the input method switching, otherwise, the user has to manually switches to the right input method.

The inputmode is only a "hint", or suggestion, for the input method, it doesn't prevent the user from switching to other input methods manually, as they like, and it doesn't validate the acutally input from the user.

The patch addresses the WebCore part of this feature, and each porting need to implement a platform-specific interface to actually switch the input method, this can be done in an existing interface:  EditorClient::setInputMethodState(bool).

Before this patch, EditorClient::setInputMethodState(bool) only enables/disables the input method, automatically when the focus is on text node / non-text node.  The implementation of this API should also be responsible for switching to the right Input Method based on the inputmode value, so we are not going to  introduce a new API for EditorClient.

The patch contains a reference code in for QT, other portings can do similar to switch the Input Methods based on inputmode value.

[Alexey Proskuryakov]

Some comments in passing:

+contains(DEFINES, ENABLE_XHTMLBASIC=1): FEATURE_DEFINES_JAVASCRIPT += ENABLE_XHTMLBASIC=1

The feature should be implemented in a way that it either works, or is undetectable from JavaScript - even if someone mistakenly enables the feature define, this invariant shouldn't be broken.

+// The code is here for reference purpose, each platform should implement the input mode switching based on 
+// the platform capability and the inputmode attribute, like digit, upperCase, lowerCase, or any language-specific
+// input methods
+
+#if 0

We don't normally land commented out code. And implementation for a specific platform is not a place where one would easily find such explanation.

+        Need a short description and bug URL (OOPS!)

It does!

Is there a reason for the test to not be dumpAsText?

Actually, let me turn the above into a formal review, r-.

Alexey,  thanks for reviewing .

Will you please elaborate what you mean with above comments?   As I said in above comments,  this patch only addresses the WebCore part of this feature,  and each porting need to have the platform/device specific implementation for input-method switching.  Anybody who enables this feature with ENABLE_XHTMLBASIC need to have their own implementation to get it working.  But without this patch,  they hve no way to get it working.

Are inputmode() and setInputmode() really needed?  We can omit them by adding [Reflect] in IDL files, and platform-dependent code can access them by getAttribute() and setAttribute().

Thanks Kent for the review .

Resubmitting following Kent's comments,  with the following comments:


1. Removed the HTMLTextFormControlElement::inputmode() and HTMLTextFormControlElement::setInputmode(), and add modifier "Reflect" in the idl file of HTMLInputElement and HTMLTextAreaInput so that we don't need to define inputmode() and setInputmode() 

2. The test cases will be automatically skipped by unsupported platforms, we don't need to add them to skip files.

You need to change more files to introduce a feature flag. e.g. */FeatureDefines.xcconfig, features.gypi.  Bug#40878 has a good example.

WebCore/html/HTMLInputElement.idl:103
 +                   attribute [ConvertNullToNullString, Reflect] DOMString       inputmode;
You don't need ConvertNullToNullString anymore.  Reflect implies it.


WebCore/html/HTMLTextAreaElement.idl:56
 +                   attribute [ConvertNullToNullString, Reflect]  DOMString            inputmode;
ditto.

WebKitTools/ChangeLog:5
 +          Add feature "XHTML Basic 1.1 support with ENABLE_XHTMLBASIC
Unclosed "

Should this be implemented at all given that it is not in HTML5?

[sideshowbarker]

(In reply to comment #18)
> Should this be implemented at all given that it is not in HTML5?

Also, I don't know of any other deployed UA that actually supports the inputmode attribute.

So, another thing to consider is whether there's actually any existing content (even WAP/mobile-only content) that uses the inputmode attribute. It would seem like there would not be -- since there's no other UA that supports inputmode.

But if this starts shipping in Webkit-based browsers, then it is likely that some content providers will start using it. I think we should be carefully considering whether we want that to happen -- because then other UA vendors will then be expected to add support for it as well, and incur development and testing costs in order to do that. So the question is whether inputmode is important enough that all UA vendors should add support for it.

An important thing to note is that inputmode essentially duplicates functionality that's already provided in most deployed mobile UAs through other means -- chiefly through the "-wap-input-format", which has for better or worse become a de facto standard, and is (as I understand it) already supported in Webkit and in Opera and in all modern WAP browsers.

And the -wap-input-format is already used in a huge amount of existing (mobile-only/mobile-friendly) content. So to some degree, the inputmode is reinventing a wheel in spite of that fact that there's no actually no market need/demand for it to be reinvented.

All that said, I'll concede that I am not really up to date with details of the current market situation around mobile browsers, so it could be that what I have written above no longer applies.

[Dominique Hazael-Massieux]

-wap-input-format isn't actually supported by most Webkit mobile browsers as far as I know; it isn't supported on the iPhone for sure.

Currently, the iPhone relies on form control names convention (e.g. including phone or zip in the name of the field) to trigger the numerical virtual keypad, which seems suboptimal at best.

I think the inputmode attribute has clearly a role to play to improve keyboard input on mobile devices, esp. with the rise of virtual keyboards.

It used to be part of HTML5, but was removed due to lack of implementations (from what I remember) — so I'm hoping a proposal to implement it won't be blocked by its lack of inclusion in HTML5!

From what I know, Opera has the infrastructure to implement the inputmode attribute (i.e. it is properly parsed as part of the DOM), but hasn't exposed it in its deployed browsers (yet?).

To summarize, I really hope inputmode is given a chance, and ends up being added to HTML5; I can't count the number of times I wish it was available on Web sites I visit from my mobile devices...

<rdar://problem/6234688>

[Elliott Sprehn]

Is the issue trying to be tackled here resolved by the new HTML5 input types like "tel" and "number" ?

There's only a few things that seem to be missing wrt. to inputmode like telling the browser not to capitalize the first letter.

[sideshowbarker]

Yesterday Hixie added a new inputmode attribute to the current HTML5 spec:

  http://www.whatwg.org/specs/web-apps/current-work/multipage/association-of-controls-and-forms.html#attr-inputmode

It's not based on the existing spec for the XHTML Basic 1.1 inputmode attribute. It doesn't (yet) allow modifier tokens, for one thing.

inputmode is supported by WebKit now.
