How to get information about the pressed key in Yandex Browser for Android in JavaScript?

Question

JavaScript

The script is such that if a key is included in the given form restrictions (only Russian/only English letters and numbers, etc.), then it is entered into the form in a modified format (for example, in upper case). Everything works on a PC and on IOS, but on Android Yandex Browser gives Unidentified for the event.key property, and 229 for event.keyCode and event.which - 229 (for any key). So how to get information about the key on Android in Yandex Browser? I couldn't find any information on this topic in a search.

Answer 1

I did not find an answer to the question, but I decided this way: instead of keydown on android, I used keyup, and if the length of the string changed, then it worked with the last character.
