Hello! The site uses 2 currencies. Each is used for its region. There are no problems in php, everything is set up,

$arItem["FULL_PRICE"] =  CCurrencyRates::ConvertCurrency($arItem["FULL_PRICE"], 'RUB', "USD");

but in the cart, when updating the quantity, the currency of the product is pulled up by default. How to convert it to script.js?

Answer 1

Convert it on the site side to mutator.php.
No need to do the same task in two different places. Especially on opposite sides of the network.
