将PHP数组发送到在echoed string中调用的JS函数

I have a multidimensional array and want to send it as a parameter to JS function. Google told me that json_encode() is the way to go, but I get an unterminated string literal error when I try to call the function.

Here's my code:

$wynik_artefakty = $polaczenie->query("SELECT * FROM artefakty"); 
$tablica_artefakty = mysqli_fetch_all($wynik_artefakty,MYSQLI_ASSOC);
$tablica_artefakty = json_encode($tablica_artefakty);

 echo "<div class='wpis' 
       onclick=\"dodajDiv('$tablica_artefakty')\">" 
      .$tablica_jednostek[$i]['nazwa']." ".$tablica_jednostek[$i]['koszt']."</div>";

And the example echo of the array after json_encode():

[{"Id":"2","nazwa":"Sceptre of Atrocities","personal":"The 
Gorgon","dla_maga":"0","koszt":"15"},{"Id":"3","nazwa":"Artefakt dla 
maga","personal":"","dla_maga":"1","koszt":"10"}]
