let str = "1 turkey costs 30€";
let reg = /\d+(?=(€|kr))/; // extra parentheses around €|kr
let regexp = /\d+(?=(€|kr))/; // extra parentheses around €|kr
alert( str.match(reg) ); // 30, €
alert( str.match(regexp) ); // 30, €

```js run
let str = "1 turkey costs $30";

let regexp = /(?<=(\$|£))\d+/;
alert( str.match(reg) ); // 30, $
alert( str.match(regexp) ); // 30, $
```
