1847687 - Consider using isFocusable instead of isVisible when determing whether a field is eligible for address and credit card autofill

Status: RESOLVED FIXED

(Toolkit :: Form Autofill, task, P3)

Description

[Dimi Lee [:dimi]]

We have seen in some cases, a field is not visible but should still be autofilled (state field in Bug 1835852, expiry month/year in Bug 1845321).

Maybe we should use "isFocusable" instead of "isVisible"? If this is the right thing to do, can we use elementIsFocusable[1]?

@edgar, we had chatted about this during the AllHands, but could you help confirm again that elementIsFocusable is the right API to use for our use cases, thank you!

Yes, you can use elementIsFocusable with flag=0 to check whether a element is focusable, i.e. does the focus can be moved to a element either by mouse clicking or calling element.focus(). And if I read code correctly, you can also use FLAG_BYMOUSE to check whether a element is focusable by mouse clicking.
