How to automatically detect the portal language?

Question

1C-Bitrix

How to set up to automatically determine the required language of the site for the user?
There is a portal with the ability to switch to both Russian and English manually.
Portal in the .com zone
For example, an English user in the UK opens a portal. The portal at the entrance opens in Russian. Yes, he can manually switch to English - there is such an opportunity.
But how to set it up so that this Englishman has the opportunity to immediately open a portal in English?
Where are the settings made - on the browser side? Maybe a plugin is needed?
Or is it to finish with the code on the side of Bitrix24?

Answer 1

You can use js to determine the default language of the browser

var userLang = navigator.language || navigator.userLanguage; 
console.log(userLang);

and either redirect to the English version, or simulate, through js, clicking on the English button. language per user =)
