How can I do language switching in PhoneGap/Cordova?

Question

HTML

Good evening.
How can I switch the language?
As far as I understand, this won’t work through a regular cookie, it’s necessary through localStorage.
I’m trying to make it so that when the desired radio is selected, it redirects to the index-ru.html page, or if the language is eng, it redirects to the index-end.html page And so that when you re- when you enter the page, the active value is taken from the cookie and redirected to the desired page itself.
Can you suggest how this can be done?

<p>
    <label><input type="radio" name="set-lang" value="RU" /> RU</label>
    <label><input type="radio" name="set-lang" value="EN" /> EN</label>
</p>

<script>

    function langRoute(){
        if (localStorage.getItem('lang')=='RU' ) window.location.href = 'index-ru.html';
        if (localStorage.getItem('lang')=='EN' ) window.location.href = 'index-en.html';
    }
    
    $(document)
    .on('change','input[name="set-lang"]',function(){
        
        localStorage.setItem('lang',$(this).attr('value'));
        langRoute();
        
    })
    .ready(function(){
                langRoute(); //Если нужно запомнить выбор пользователя
            })

</script>
