[Christinadobrzyn]

Looks like we have a few focus/cursor issues but I think this one is different.
I assume what we want is either

• The cursor to remain on the "Phone or email" line even when clicking the other parts of the landing page
• Prohibit highlighting the landing page as we do with old dot and on the mobile apps with NewExpensify

Proposal

Please re-state the problem that we are trying to solve in this issue.

magic code input is autofocused

What is the root cause of that problem?

a few things combined:

• MagicCodeInput's initial state value for focusedIndex is 0 ( index of the first input which gets highlighted ).
• in BaseValidateCodeForm we not only add autoFocus prop to the MagicCodeInput component but also insist on auto focus by invoking MagicCodeInput's focus() method manually when the component mounts

What changes do you think we should make in order to solve the problem?

two things:

• initialise focusedIndex state as undefined ( no input is initially focused )
• pass autoFocus prop to MagicCodeInput with the value of false
• remove this.inputValidateCode.focus() call on BaseValidateCodeForm's componentDidMount level

What alternative solutions did you explore? (Optional)

none.

Proposal

Please re-state the problem that we are trying to solve in this issue.

DEV: magic code input remains highlighted even after not being focused

What is the root cause of that problem?

We are just setting focus when pressed or mounted, but we should also remove focus when onblured

What changes do you think we should make in order to solve the problem?

We should add onBlur method to magic code input. In this method we should check if focus is really being sent outside of input groups like this:
_.includes(this.inputRefs, e.nativeEvent.relatedTarget)
and if it does, set focusedIndex and editIndex to undefined. If we do not check for the focus destination, when entering numbers focus will flicker, and also deleting numbers won't work as expected as well.

Proposal

Please re-state the problem that we are trying to solve in this issue.

Magic code input remains highlight even after being blurred

What is the root cause of that problem?

We're setting highlight when pressed but no logic to remove highlight when blurred

What changes do you think we should make in order to solve the problem?

Add onBlur callback on TextInput in MagicCodeInput.
In this callback, if this.inputRefs doesn't contain e.nativeEvent.relatedTarget, clear focusedIndex, editIndex to undefined. This condition is needed for left, right arrows to work. We should not clear focusedIndex, editIndex values when focus is transferred from one input to another input. They should be cleared only when all 6 inputs are blurred.

Improvement: to make Tab/Shift+Tab key work similar to left/right arrow, use onFocus callback instead of onPress callback and deprecate old onFocus callback.

Note: my proposal cannot be similar to @alitoshmatov's proposal. Here's the first reason: #15486 (comment)

[Santhosh-Sellavel]

@situchan What's different in your proposals?

As far as I can see the @alitoshmatov proposed the solution first here even including edits.

[situchan]

yes, I had thought if edited proposal was earlier, it would have been acceptable.
But in #15486, my proposal was not accepted even though my edited proposal was earlier than accepted proposal, only because I didn't post new comment "Proposal updated".

[situchan]

cc: @marcochavezf @mallenexpensify as you were assigned on related issue

[alitoshmatov]

I just thought it was ok since there were not any proposals after mine at the time when I was updating

[Santhosh-Sellavel]

I do not have the full context of #15486. Just my thoughts on this matter.

It's okay to edit the proposal before C+ starts reviewing.
But once the proposal review has started it's important to leave an updated comment message.
If the changes are just improving the existing approach it's okay to edit, But if the approach changes or more changes it's better to leave a new comment mentioningProposal 2or updated proposal at the start of the comment.

@situchan I think this is not the place to continue this discussion here. If still something unresolved please start a discussion in Slack in Expensify-bugs or Expensify-open-source, thanks!

[situchan]

Here's is full context ☝️

I don't mind which proposal is accepted here but just for consistency between issues so no one has doubt.

[Santhosh-Sellavel]

As I mentioned early here

@situchan I think this is not the place to continue this discussion here. If still something unresolved please start a discussion in Slack in Expensify-bugs or Expensify-open-source, thanks!

Thanks again!

[aimane-chnaif]

I suggest to hold this for #18398 where MagicCodeInput component is being refactored to functional component.

[dangrous]

I don't think it'll hugely matter either way since it'll come up as merge conflicts for whoever tries to push first but yeah let's hold for now so we don't have to make changes twice (not a big issue so the delay will be fine)

[dangrous]
