Results disappears on keyboard dismissal on iOS

[NiklasBr]

On iOS 16 searching and then dismissing the keyboard to scroll in the results will cause the results to disappear. It would be very good if they stayed

Created because #74 was incorrectly closed.

On IOS, if you close the keyboard, safari will automatically unfocus/blur the textbox and thus the widget will remove all suggestions. Here are some topics on stackoverflow that discuss this issue:

https://stackoverflow.com/questions/5652322/how-to-prevent-a-js-blur-event-in-ios-webkit-when-the-virtual-keyboard-is-dismis

I'm not aware of any good workaround to prevent this, but if you have any suggestions, you can post them here.

I think it would be a good idea to not remove the DOM on blur, or allow implementations to override the onBlur event which removes the content.

Sadly this is a real deal-breaker for me. If you type a on the demo and then hide the keyboard, the suggestions disappear. If you keep the keyboard, you cannot reach the last entries because these are overlayed/blocked by the keyboard.

Hi @atomtigerzoo and @NiklasBr

I've developed a fix to address this issue and it should prevent the autocomplete from closing when user is closing virtual keyboard on IOS devices.

Please note that this solution is a bit of a workaround, as it extends the delay before the autocomplete closes following a blur event from 200ms to 800ms. This means that if a user clicks somewhere else on a webpage, the autocomplete widget will remain visible for a longer period than before (but only on IOS devices).

You can install this fix using the following command:

npm install --save-dev kraaden/autocomplete#2cbac7b8e56bf5e1e64bb19318c9e59f16b919c3

I have addressed the issue of increased delays on iOS devices. The delay should now be consistent at 200ms across different devices. Please update to the latest version by running the following command:

npm install --save-dev kraaden/autocomplete#1fb9967df8f0142678730baba346202c2905746c
