get String value not as hex from smartcontract - solidity

Question

I got a smartcontract function returning several values on of them as string
I've trying to transform this number to UTF with web3 and is not working.
If I try it on remix calling the smart contract it's works fine... but not from JS
my current code in the smart contract are
function getToken(uint256 _tokenId) public view returns (
string _tokenName,
string _cryptoCardID,
uint256 _price,
uint256 _nextPrice,
address _owner
) {
_tokenName = doggies[_tokenId].name;
_cryptoCardID = doggies[_tokenId].cryptoCardID;
_price = tokenIdToPrice[_tokenId];
_nextPrice = nextPriceOf(_tokenId);
_owner = tokenIdToOwner[_tokenId];
}
from JS
for ( var i = 0; i < result; i++){
myfunction.getToken.call( i , function (error, resultGetAll) {
console.log("Token ID:"+i+ "Data:"+JSON.stringify(resultGetAll)); //here i get _cryptoCardID as hex 0x000000...
}) // each one
}// for
what I expected is a string in readable form (utf8)

Answer 1

Contracts will store the binary data, so returning the data in hexadecimal form is a more efficient way of viewing this data.
You can always decode the hex to utf-8 with a utility function from the web3 library.
Note: this method may differ depending on your web3 version, see here for web3.utils.hexToUtf8 alternative.
Example:
$ web3.toUtf8("0x68656c6c6f20776f726c640000000000000000000000000000000000000000")
$ "hello world"
tested on web3 version: 0.20.3
