Is there a way to write semantic HTML for checkboxes where it won't read it as "unlabeled, check box"?
The following html results in "unlabeled, check box, not checked, Yes" to be read by the screen reader.
<p>Is this checkbox selected?</p>
<input type="checkbox">
<label>Yes</label>
Opening NVDA's Elements List on Interactive Accessibility: Training 3.2 which claims this is the accessible example also results in "unlabeled, check box" treeview entries to be generated.
Is there a way to write checkboxes to ensure they aren't marked as "unlabeled"? Or is this a quirk of NVDA itself?
This is actually a Chrome browser defect. I'm not aware of a workaround, but one would not be recommended, as it could alter correct behavior in other browsers and screen readers.
For more information check the NVDA issues list on GitHub:
Unlabeled is prepended before labelled radio elements while in elements list
I see your example is incomplete with IDs, but I understand what issues you are talking about. It will happen no matter how good is the markup with native or ARIA checkbox controls.
Add some id in your label and add aria-labelledby in the input. The value of aria-labelledby should be the id of the lebel. Hence your code block should be something like this:
<p>Is this checkbox selected?</p>
<input type="checkbox" aria-labelledby="someId">
<label id="someId">Yes</label>

Any idea why NVDA reads clickable word when tabbing through text in html example:
<h1 tabindex="1"> testing </h1>
NVDA will read clickable testing
In first place remember that tabindex are not a good practice in a11y, and also headers don't need a tabindex NVDA provides a header navigation with the H key. About the clickable I can say from my experience is a known issue for NVDA, if you check that in other SR (Voice over or Chromebox) should be read properly
Short answer:
the tabindex attribute implies functionality to some screenreaders.
Long answer:
Two primary ways that a screen reader user will navigate your webpage are by skipping through interactive elements or by headings. Interactive elements are things like links, buttons, form fields and any other piece of functionality that the user will initiate on your page. These are navigated by using the 'tab' key.
The other primary way they will navigate your page is by headings. In fact, a survey from webaim lists headings overwhelmingly as the primary method of navigating a page to find information (source). In your example, you have given the heading a tabindex which will give the impression that it has some functionality or interactivity to it. To my understanding, both JAWS and NVDA will read out 'clickable' on elements that have a tabindex, as they could easily (and typically would) have some javascript click handlers that are not evident from the screenreader.
Answer:
It's because of attribute tabindex which makes this element keyboard focusable. One can focus it by pressing TAB key on a keyboard.
Hint #1: Attribute tabindex with value above 0 should be generally avoided!
Don't use tabindex="1", tabindex="2" and so on. Only tabindex="0" or tabindex="-1" can be useful in some cases. Otherwise you can create a complete mess for a user experience.

Google: Using a tabindex greater than 0 is considered an anti-pattern.
WebAIM (accessibility): This is almost always a bad idea.
MDN: Avoid using tabindex values greater than 0.
Hint #2: Generally no need to make focusable elements that a user cannot interact with.
As in specific case no sense to make a heading element keyboard focusable if a user cannot interact with it.
If you are concerned about screen reader users have no worries as they read non focusable content just fine. A quote from Accessibility Developer Guide: As opposed to keyboard only users, screen reader users usually do not use the Tab key to read a page! Read the "Screen readers browse and focus modes" to know the difference between navigation using Arrow keys and Tab key.
But... Exception to the rule exists
Exception to the rule exists and it's probably a good idea in cases where developers set tabindex="-1" to headings which they want the focus to be moved programmatically for the purpose of accessibility. Such cases are for example fresh content update with AJAX in single page applications. The focus would be moved to a heading for a user to get aware of the content update and to be able to start from there. Also it can be useful when currently focused content is about to get removed from the DOM (a.g. deleting currently focused table entry) or moving a focus to an error summary heading after a form submit trial etc.
In my case (VoiceOver on MacOS), it seems that H1 is announced as clickable only on Firefox. On Chrome, it's announced correctly.
This leads me to believe it's a Firefox bug.
In Sitecore MVC, FieldRenderer.Render(Item, "Field Name") automatically checks its field type. In another word, all XSLT extensions (sc:text, sc:image, sc:date, …) is affected by the RenderField pipeline.
But, I couldn't find sc:checkbox information and it doesn't show "CheckBox" in page edit mode. It just shows the value of the check box.
How can I make it show as like input type=checkbox in page editor?
Sorry for the link only answer but the general approach here is to use a Field Editor Button.
This will open a pop up window with the content editor style control for the field.
If using a custom experience button is not an option for you, you can output different markup (i.e. your input button) to the client when the page mode is in 'Edit' mode.
This will allow you to present the author with the controls you wish to display, but still output the normal output values for end users.
If you are able to use controller renderings, you can use the controller to load a different view to make this easier, but otherwise you can use if statements within your View to output different markup.
I could have been in a search for this. Once the form is submitted , if the errors are available it shows on top as the validation summary (May be it will be done). Here is the critical. When i click on the error message, the focus should go to the corresponding error field. The field may be in the same tab or other tabs or other panels etc
Could it be possible to achieve?
A simple way to achieve that would be to make the error message a label for that particular field:
<label for="myField">some error</label>
&
<input id="myField">
Clicking on the message would then automatically focus the field, no matter how far in the DOM the two elements are from each other.
An input can also be focused by JavaScript (see .focus() documentation). In both cases, the input needs to actually be present in the DOM before it can be focused.
I'm new to iAd Producer - what I'm really looking for is a replacement for Dashcode, since Apple seems to have abandoned it. But while it looks as though iAd Producer CAN produce iBooks Author widgets, it seems to be missing a few fundamental objects - namely checkboxes and radio buttons.
I'm sure there's a way to hack HTML and perhaps use jQuery to get the job done, but this was a relatively simple, straightforward thing in Dashcode. Am I missing something? With tools like buttons, sliders, and such, I'd think checkboxes and radio buttons would be included.
Anybody know an EASY way to replicate Dashcode functionality in iAdProducer?
Thanks!
I've had the exact same problem for the last week and finally came across a solution. You can "escape" the checkboxes in a way by including an empty onclick property to the checkbox or label that you want to affect. This should override native code that relates to cut-and-paste gestures and make checkboxes unusable. I've had success with this in iBooks Widget Tester.
Funny... we seem to be working on the same issue at the same time. Closest I've got to a solution is to build in iAd Producer using the HTML template. There you can add in the objects that are missing using HTML code while also adding drag and drop objects available in the software.
However, while I can populate my view with checkboxes and get them to be checked in iAd Producer's preview, when I preview on my iPad, I can't check the boxes. Radio buttons remain unresponsive too.
I noticed that on certain websites, if you want to tick a checkbox on or off, you just need to click the corresponding text. When I put a checkbox with some descriptive text on my page, I have to actually hit the checkbox for it to get ticked. How is the former effect achieved?
Consider using a <label> as in this example:
<input type="checkbox" name="call" id="willcall">
<label for="willcall">click on this text to select the checkbox</label>
This example from: http://www.askdavetaylor.com/make_text_adjacent_to_checkbox_clickable.html
I'm sure that they use a JS script to achieve this. It's most likely a label that is being clicked, and they might add an onclick() event to the label which uses the javascript to find the checkbox and add the CHECKED attribute to it. Sorry for not supplying code, but I hope that gives you some understanding on what those websites do.
