QUESTION
I've written and optimized a Shiny app, and now I'm struggling with the IT section of the organization where I work to have it published on their servers. Currently, they are claiming that the app is not W3C compliant, which is true, according to the W3C validator.
The errors I'm trying to solve, with no success, are:
Bad value “complementary” for attribute “role” on element “form”.The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.
Such errors can be seen also in very minimal shiny apps, like:
...ANSWER
Answered 2022-Mar-04 at 08:05The following only deals with the first of the errors you mention (as this one is pretty clear thanks to @BenBolkers comment), but hopefully it points you to the right tools to use.
I'd use htmltools::tagQuery to make the needed modifications - please check the following:
QUESTION
I have an HTMLElement
, which is found and set in a variable that will not focus when using .focus()
. Since this is an Angular app, I have tried using nativeElement
to focus, but the element is not found.
Acceptable answers can use either method and maybe others, as long as it doesn't involve using an extra library like jQuery.
...ANSWER
Answered 2022-Jan-25 at 10:26Seems to work for me. I implemented NgAfterViewInit
to run your method and refactored a little bit. We can access elements in template after their rendered via NgAfterViewInit (the earliest). We then reference to the element as HTMLElement, instead of ElementRef.

QUESTION
I currently have a simple bit of markup on my site, and can't seem to get a screen reader to read it. Am I missing something?
...ANSWER
Answered 2021-Oct-15 at 20:51ACcording to ARIA specification, the
So, conforming screen readers are supposed to read it, and, as far as I have tested, they indeed do.
Attribute aria-description is more recent than aria-label, so you should prefer aria-label in order to maximize the chances to have it read.
IN order to make good and relevant tests, I suggest you to use a true screen reader really used by users, rather than a browser extension that nobody use in the real life. You may try one or more of the following, depending on your target systems and possibilities: (Non exhaustive list)
- NVDA, Jaws and Supernova under windows
- VoiceOver under MacOS, iOS and iPadOS
- Talkback and VoiceAssistant under Android
NVDA, VoiceOver and Talkback are totally free, and VoiceOver is even always available out of the box without the need to install anything. So you really have no reason to don't try them out.
QUESTION
I have been working on an App called CtrlPanel for the company I work for. This app was originally running on Ruby v2.2.2 and rails v4.2.1. I could not get that environment to work on ANYTHING; I tried both PC and Linux. Since I couldn't get that environment running and since it needed to be updated to the newest version anyway I figured I would just get it working on the latest version.
I had no idea what I was in for, that was a little over a month ago. I am happy to report I now have everything in the program working with one exception. There is a catalog that displays all of the items and it uses a scope in the model with a lambda expression that is rather complicated (at least to me). I have had to update the syntax ALL over this application due to the older version of Rails and now being on the newest version and this is the only one I can't seem to figure out. I am pretty sure again that it is just a Syntax problem from Rails v4.2.1 to Rails v6.1.3.1 but I just can't seem to figure it out and I am sure people who are more experienced than myself will know what it is.
Here is the model in question:

QUESTION
I have a table with X number of rows and at most 5 columns. The user will enter values in Row 1, column 2 then I need to navigate them to Row 2 Column 2 to enter the next value. When they are on the last row for Column 2 then they need to go to row 2 column 3 and so on. They are entering numeric values with a specified number of decimals. Once they enter the appropriate number of decimals I need to force them to the next row/column based on above logic.
I have set the tabIndex so that it gives me the desired effect. I put my cursor in the first row column 2 and press tab, and it goes down the rows and then over to the next column so pressing the tabKey works:
...ANSWER
Answered 2020-Dec-08 at 17:08You can check if there exist next
tr or not if yes then just use input.closest("tr").next().find("[tabindex=" + tabs + "]").focus()
i.e : to td where tabindex is same and if doesn't exist get the td[contenteditable=true]:first
tabindex value and use this to put focus on required td.

QUESTION
I'm creating an unordered list of buttons and would like to make it accessible. (Note: I found this SO post, but it doesn't answer my question.)
My code (simplified, in React) looks like this:
...ANSWER
Answered 2020-Nov-18 at 00:47If you have several cases of such long groups, you should probably provide other means to navigate as well. Headlines, for example, which would allow screen reader users to skip such groups or target a specific one.
Concerning tab navigation: I stumbled across a pattern called a roving tabindex, which is explained well on MDN's Keyboard-navigable JavaScript widgets page
The technical implementation is as following:
- Do NOT make the container focusable
- Make only the first item in the list (menu) focusable by giving all others to
tabindex="-1"
- Add React logic to move (implicit)
tabindex="0"
attribute between items by means of arrow keys
There seems to be the npm package react-roving-tabindex that already implements that logic, even with grid-navigation.
Otherwise a quick-fix might be to provide a hidden skip link just before the list of buttons that allows jumping over them. I'm assuming you are providing a title for your list?
QUESTION
I am beginner in Angular, I am working with users information so, in my page I have the option to create a new user, in down I have a table that show the user's information. In this I have 3 buttons, Details, Edit and Drop, I have a modal to see and edit the information so, I am using a index to know what is the "row" or "user" selected, Details and Delete are working fine; but when I test the edit function is getting a empty form to my service, is strange because when I click again on edit for this particular user the "new" information is there. I am trying to use the same reactive Form that I am using for create new user . Someone can help me to undestand what I am doing wrong? Thanks a lot
This is my html table-modal code
...ANSWER
Answered 2020-Oct-15 at 14:27Explicitly created Form controls are no longer needed; because the ngModel creates them automatically!
