		"usd": 110.5420
	}
	
	const k = v * valute[valIz] / valute[valU]
	window.alert( valIz.toUpperCase() + "u" + valU.toUpperCase() +
                       ":" + k	)
	}	
}

buttonKonvertuj.onclick = konverzija

What I have tried:

JavaScript

const buttonKonvertuj = document.getElementById("konvertuj")

function konverzija() {
	
	const inputVrednost = document.getElementById("vrednost")
	const inputValutaIz = document.getElementById("valutaIz")
	const inputValutaU = document.getElementById("valutaU")
	
	const v = Number(inputVrednost.value)
	const valIz = inputValutaIz.value
	const valU = inputValutaU.value
	 
	const valute = {
		"eur": 117.3201,
		"rsd": 1,
		"cad": 81.2437,
		"usd": 110.5420
	}
	
	const k = v * valute[valIz] / valute[valU]
	window.alert( valIz.toUpperCase() + "u" + valU.toUpperCase() +
                       ":" + k	)
	}	
}

buttonKonvertuj.onclick = konverzija

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.

It is very difficult to know what the problem is with the explanation you give.

First of all: each statement should be ended by a ;

const buttonKonvertuj = document.getElementById("konvertuj");

function konverzija() {
	
	const inputVrednost = document.getElementById("vrednost");
	const inputValutaIz = document.getElementById("valutaIz");
	const inputValutaU = document.getElementById("valutaU");

and so on...

If that doesn't work, try something like:

function konverzija() {

alert("Entering the body of the function);
	const inputVrednost = document.getElementById("vrednost");
alert("Before inputVrednost");
	const inputValutaIz = document.getElementById("valutaIz")
alert("Before inputValutaU");
	const inputValutaU = document.getElementById("valutaU");
alert("Before v");	
	const v = Number(inputVrednost.value);

and so on...

That way you will be able to know which instruction really has the problem.
