Shopify auto currency based on user's location (without needing to refresh)

auto-currency.js

<script>
   function setCookie(key, value, expiry) {
     var expires = new Date();
     expires.setTime(expires.getTime() + (expiry * 24 * 60 * 60 * 1000));
     document.cookie = key + '=' + value + ';expires=' + expires.toUTCString() + ';path=/';
  }
    
  $(document).ready(function () {
     // You need to enable the currency that you want to be supported under shopify settings/payment
     var currency = {"GR":"EUR", "JP":"JPY", "PH":"PHP", "US":"USD"}; // Add capital and currency 
        $.get("https://ipinfo.io/json",  (location) => {
             var userCurrency = currency[location.country];
             setCookie('cart_currency', userCurrency, '1')
        },"jsonp");
  });
</script>

@Drewberrysteph - is there any way to do a default currency?

I have a Danish shop. It is in DKK for all Danes.
I support another 5 currencies, which I would match up with a country code.
However for all other countries I would like EURO as default - and I would very much like to avoid having to pair all countries in the world with EURO :)

@numzie try to replace line 12 with

var userCurrency = currency[location.country] ? currency[location.country] : "EUR" ;

I think you have an extra curly bracket on line 14. Anyhow, I still need to reload for the currency to switch.

`<script> 
  
  
   function setCookie(key, value, expiry) {
     var expires = new Date();
     expires.setTime(expires.getTime() + (expiry * 24 * 60 * 60 * 1000));
     document.cookie = key + '=' + value + ';expires=' + expires.toUTCString() + ';path=/';       
  }
    
  $(document).ready(function () {
     // You need to enable the currency that you want to be supported under shopify settings/payment
    var currency = {"IT":"EUR", "BR":"BRL", "CO":"COP", "ES":"EUR", "BO":"BOB","CL":"CLP","EC":"USD","GY":"GYD", "MX":"MXN", "PY":"PYG","PE":"PEN","PT":"EUR","SR":"SRD","UY":"UYU","VE":"USD"}; // Add capital and currency 
    $.get("https://ipinfo.io/json",  (location) => {
             var userCurrency = currency[location.country];
             console.log(userCurrencyconcat("JOVA"));
             setCookie('cart_currency', userCurrency, '1')
        },"jsonp");
  });

</script>`

This is my code, did do something wrong?

@Jovdza012 Thanks, try to clear cache before testing.

I did, I am testing it with a VPN and with a clean browser every time (I use the guest account on chrome). I put it in theme.liquid file, below the Facebook tracking code, and before the theme loads its CSS :/
