Can KeyboardEvent.repeat ever be true for a keyup event?

[aycyang]

What would it mean if the KeyboardEvent.repeat attribute were true for a keyup event? Is it allowed? The spec doesn't seem to address this question. In the keyup section, the bullet point for KeyboardEvent.repeat says the same thing as for keydown:

true if a key has been depressed long enough to trigger key repetition, otherwise false

I think more clarity is needed here.

Hi @aycyang Do yo think will something like this justify? "For keyup events, repeat reflects whether the key was held long enough to trigger repetition before release . It does not indicate repetition during the keyup event itself."

[aycyang]

For keyup events, repeat reflects whether the key was held long enough to trigger repetition before release

Is that right? In my testing, repeat is always false for keyup events.

I observed the same behavior, repeat is always false for keyup events in my tests too. I agree that adding a note like repeat is always false for keyup events would clear up the ambiguity.

Your earlier phrasing 'repeat reflects whether the key was held long enough to trigger repetition before release' is technically correct, but since keyup only fires on release (when repetition stops), the simpler note might avoid confusion. Please share your thought?

Assuming that's true, then yes it would.

That's not my phrasing, I was quoting you.

Gotcha, thanks for pointing that out! 😅 Would it make sense to add a note to the spec or documentation along those lines?
Appreciate your attention to detail, this clarified the behavior much better.

This is a question for the spec authors.
