How to use JavaScript inside PHP in Laravel?

Question

JavaScript

The task is the following: count the number of elements in JS and display the number with the correct declension (eg "1 order / 2 orders / 5 orders") using Laravel lang files.
At first, I used a simple JS function for declensions, and simply stored three different declensions in lang files. After that, I was told that it is wrong to do this and there is a standard function in Laravel that does this trans_choice. But there was a problem when integrating the JS variable into the PHP code of this function. It turned out something like this (in a simplified form):

// определяем количество карточек в колонке
var cardsLength = 3;
// и записываем
countText = cardsLength+' {{ trans_choice("sales_order.order_declension", '+cardsLength+', [], "ru") }}';

Of course, the code did not work adequately and always displayed the third declension option. The problem obviously arises from the fact that the php code does not see the value of the JS variable, but perceives it as plain text.
Unfortunately, I could not think of any working options (well, except for a rather ill-conceived option using the JS declination function). Who can suggest the most elegant solution to the problem?

Answer 1

At the time of rendering the page, Js has not yet been worked out.
Still, I advise you a way to solve this in a standard way.
PS Write in more detail what you are doing and what you want to achieve as a result - and I will try to tell you how to do it more elegantly using PHP + Js environments
