currently there is no known way, to detect this feature.

the best way to go is to detect other features, wich are related to this missing feature. (full support of validationMessage without setCustomValidity-bug, support for required select elements, output element, datalist element etc.). but this can only be decided, if the bug was fixed: https://bugs.webkit.org/show_bug.cgi?id=28649

Libraries like webassets provide the ability to merge and compress Javascript and CSS on the fly. It would be cool if you could configure Webshims like this:

$.webshims.loader_url('/jscompressor');

and then instead of loading all the polyfills from separate requests, it would do something like:

document.write('<script src="/jscompressor?scripts=es5.js,form-core.js,...">\x3C/script>');

(It should sort the list of required scripts in the url so the server and browser can cache the response.)

This could be a good first step toward one day hosting such a service centrally on a CDN, which would allow users to always load only the shims they need with a single request without having to host Webshims themselves.

Prior art:

• YUI Configurator (allows loading only the pieces you need from a single request)
• jquery.validate (hosted on Microsoft's AJAX CDN)

Thanks for considering!

• only if no role
• address - contentinfo
• additional test for contentinfo and banner (not in section/article) (speed improvement don't use :last/:first)

Environment: Safari 5.0.4 / Mac OS X 10.6.7

Expected result: displayed validity messages match the language specified by webshims.activeLang and correspond to the messages in the webshims.validityMessages object.

Observed result: displayed validity messages are taken from Safari itself. The webshims.activeLang call is disregarded.

Background: From http://diveintohtml5.org/forms.html: "Unfortunately, Safari and Chrome have shipped an incomplete implementation that may trip you up: they validate form controls, but they don’t offer any visible feedback when a form field fails validation. In other words, if you enter an invalid (or improperly formatted) date in a type="date" field, Safari and Chrome will not submit the form, but they won’t tell you why they didn’t submit the form. (They will set focus to the field that contains the invalid value, but they don’t display an error message like Opera or Firefox 4.)"

Reproduction steps:

1. Quit Safari if it is already running.
2. Go into System Preferences > Language & Text and drag some other language to the top of the list. I chose Portuguese.
3. Open Safari. Its GUI (menu items, etc) should appear in the language you chose in the previous step.
4. Go to a site with a validating webshims form that sets webshims.activeLang to some other language and specifies corresponding validityMessages. For instance, http://1.bravenewsoftware.appspot.com/zh/ sets webshims.activeLang to "zh", and adds validityMessages in this language. (The code for this site is here if you want to take a look.)
5. Try to submit the form with a required field missing or of incorrect type.
6. Observe the message you get is Safari's own validity message translated into the language it was started in, not a message in the language specified by webshims.activeLang, and indeed not even a message found anywhere in webshims.validityMessages.

It's an interesting question whether webshims should prefer the web site developer's chosen language/messages over the messages built in to a browser with only partial validation support. I would lean toward honoring the developers' choices (hence this bug report), but I could see how an argument could be made against. Feel free to close as invalid if appropriate.

decouple range implementation from number implementation, time from date etc.

Hello,

I want to thank you for all of the hard work you've put into this awesome framework!

I am having some difficulty with this latest version of webshims (1.6) and rendering the form elements. I have used webforms (before 1.6) with YepNope and it worked well. Now for some reason, when I make the following call, I get nothing. Using Firebug I can confirm that the scripts have loaded, but the form elements (enhanced with webshims 1.6) do not appear to be enhanced.

I am using the following code (at the bottom of the screen):

yepnope([
// load jquery
"https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js",

// other scrips are loaded here

// load webshims 1.6
{
    load     : "statics/js/libs.pollyfiller.js",
    callback : function() {
        $.webshims.loader.basePath = "static/js/libs/shims/",
        $.webshims.polyfill('forms forms-ext');
    }

]);

Any help is much appreciated.

Hey Alexander,

First off, thanks for the great work!

I'd like to use webshim for a site I'm working on which has to be available in several languages. Are there any plans to internationalize webshim? I noticed jquery.validate has translations into 32 different languages. Maybe that might be of help?

Thanks for reading. =]

• Add better support for sessionStorage (multiple window sharing) in IE6
• make localStorage work in IETester (and emulated IE7)

• how to customize/style input-widgets
• how to build polyfills
• what usefull stuff is in polyfiller.js

due to the fact, that parsing huge stylesheets adds a lot of overhead, only support for IE, where we can use internal stylesheet-parser. due to the fact, that polyfilled css3 properties don't always behave like native css3 properties make all properties optionally namespaced:

$.webshims.cssNamespace = '-polyfill-';
-->
-polyfill-transform: ...

$.webshims.cssNamespace = '';
-->
transform:

code works well, but...

http://afarkas.github.com/webshim/demos/demos/webforms/2-webforms-api.html change step to something below 0.5 for number demo + add tests.

use inline-block, margin: 0; float: none;

I'm methodically going through and testing all the MDC Canvas tutorials on FF 3 & IE 8 and am getting this error on the createPattern example on https://developer.mozilla.org/en/Canvas_tutorial/Applying_styles_and_colors

the $.fn.prop will be new and will change a lot in webshims lib

dependency, combohandler and callback logic in current implementation has to be simplified/reduced in filesize (+use jQuery Deferred Object )

form-*-ui is extremly ugly and not dry

ToDos:

• decouple spinbutton ui from native valueAsNumber support
• use shadowelements for number, time (similiar to date, range)
• don't use a real time control as part for datetime-local (use only the shadowelement)
• make replaceUI possible for spinbutton-controlled types
• localize input[type=number]
• add stepUp/stepDown method

• split into two parts
• use third party scriptloader
• use modernizr
• better code style

depends on a first real world implementation:
https://bugs.webkit.org/show_bug.cgi?id=51071

don't know how to do with datetime-local (Two input elements)

better late, than never:

1. It should be possible to plugin different scriptloaders (requireJS, yepnope).
