B2C Custom Content - Output claim value as hidden field

Question

Is there a way to output a claim as a hidden field (input type="hidden") so that it can be used inside custom JavaScript inside AAD B2C?

Setting a default value on a "ReadOnly" DisplayClaim gets the value out to the page:

      <ClaimType Id="myClaim">
        <DisplayName>DEBUG: Never display this</DisplayName>        
        <DataType>string</DataType>
        <UserInputType>Readonly</UserInputType>
      </ClaimType>

but then you have to goto extra lengths to hide it that may become fragile if the B2C HTML DOM output format ever changes:

var myClaim = document.getElementById("myClaim"); //too bad this cant just be a hidden field
var myClaimValue = myClaim.value; 
myClaim.parentElement.parentElement.style.display = "none"; //hide parent div's parent li

Not out of the box, but it would be an interesting feature that I would vote for! — Brad C., Mar 04 '21 at 16:00

If you explicitely use content version then the DOM should not change. Every custom UI template relies on DOM looking in a specific way. See docs: https://learn.microsoft.com/en-us/azure/active-directory-b2c/contentdefinitions#select-a-page-layout — wojtekdo, Mar 04 '21 at 16:38
@wojtekdo - good point, but it sill makes my client side code fragile to future template updates, whereas if there was a hidden field control i wouldnt need to write that code. — felickz, Mar 05 '21 at 05:41

That just shows you how much MSFT cares about user feedback – Jakub Bochenski Feb 08 '22 at 15:41
@JakubBochenski - updated with new link , microsoft recently back in december migrated old feedback without any way to track what you had previously followed – felickz Feb 08 '22 at 21:41

Just like I said, if they cared they would keep the old URLs with a redirect to new site – Jakub Bochenski Feb 10 '22 at 12:47

that's useful - I tried googling the title but it seems the new pages are poorly ranked as i found nothing, so it seems searching the site directly should help – Jakub Bochenski Feb 11 '22 at 22:25
