To add one more bit of context: what's implemented right now is ARIA reflection - making it possible to set and retrieve ARIA from JavaScript. A later phase of AOM will expose getting the computed role and other computed properties from a node, and then you'd expect to get the implied ARIA role from an element like an <h1>.

Alice,

Thank you for the response and you work on the AOM, I have a few questions.

I created a test page to do some testing on my own and I enabled experimental  features as described by Carolyn using Chrome Version 83.0.4099.0 (Official Build) canary (64-bit):
https://raw.githack.com/illinois-dres-aitg/aom-testing/master/index.html


I don’t seem to be getting the default role for the H1 element or the level, but do for headings created with divs.

We don't expose any computed properties - so no default roles, only explicitly set ARIA roles.

I am also curious about the ariaLabel interface, should it be giving the computed accessible name

Similarly, we're not exposing computed labels - only explicitly set ARIA labels.

For example:

<button aria-label="I am an ARIA label" id="button1">I am text content</button>

console.log(button1.ariaLabel);  // logs "I am an ARIA label"

<button id="button1">I am text content</button>

console.log(button2.ariaLabel);  // logs null - no aria-label set, does not compute label from text content

Once Chrome 81 is promoted to stable (estimated April 2<https://chromiumdash.appspot.com/schedule>), the flag will no longer be necessary to access ARIA IDL properties (other than IDREF/IDREFS properties) in Chrome.

Thanks Carolyn,

I was able to enable the AOM on Chrome.

I am curious if default roles and values of HTML elements are suppose to be reflected in the AOM, or only roles and properties that have been explicitly set.

No, no computed properties (including "default" roles) are exposed. This is straightforward IDL reflection.

Hi, Jon.

In case it's helpful, there's an IDL Button example in the APG<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c.github.io_aria-2Dpractices_examples_button_button-5Fidl.html&d=DwMFaQ&c=OCIEmEwdEq_aNlsP4fF3gFqSN-E3mlr2t9JcDdfOZag&r=9I76s_DQeMyePDM1NLeRmzQO75RtgjJ9Clf1LQyt7-I&m=CUEWT1G9KSuIIW29QTAcAf4nJccO4uGowZoCQfd1yZY&s=D03aQlTpUZt7FMZXFQPYA0oUXc9DjRhO-2PjQ2plJsg&e=>.
Here's what I had to do to enable browsers so I could test attribute reflection<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_w3c_aria-2Dpractices_pull_1161-23issuecomment-2D527296049&d=DwMFaQ&c=OCIEmEwdEq_aNlsP4fF3gFqSN-E3mlr2t9JcDdfOZag&r=9I76s_DQeMyePDM1NLeRmzQO75RtgjJ9Clf1LQyt7-I&m=CUEWT1G9KSuIIW29QTAcAf4nJccO4uGowZoCQfd1yZY&s=xwEN9x1Bwnf5-iZNe8Sp9nRgcpUNcoT41JCaB51Ad1A&e=> for that example (info from Sept 2019).
Also, this conversation with Mallory and Alice about element reflection<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_w3c_aria-2Dpractices_pull_1045-23discussion-5Fr320948178&d=DwMFaQ&c=OCIEmEwdEq_aNlsP4fF3gFqSN-E3mlr2t9JcDdfOZag&r=9I76s_DQeMyePDM1NLeRmzQO75RtgjJ9Clf1LQyt7-I&m=CUEWT1G9KSuIIW29QTAcAf4nJccO4uGowZoCQfd1yZY&s=6RlGkTZdwUn8vx9iouPBmHW7iVfVDwkjV97wtqIw9Pk&e=> may be helpful.
I don't know if element reflection has been fully implemented in any browser yet, but maybe?

This is shipping in Safari, and implemented behind a flag (enable-experimental-web-platform-features) in Chrome.



Don’t know how up to date this is.

Can someone point me to where you can learn how to enable browsers to turn on their implementation of the ARIA 1.2 IDL interface:
