ciao!

da un plugin mi arriva questo svg di default:
codice:

</svg>
io avrei la necessità di cambiare l'attributo fill a Page-1.
ho provato così:
codice:
dz.on("success", function (file, res) {
    $('#Page-1').attr("fill", "#000000");
});
viene cambiato l'attributo, ma non cambia il colore nella pagina.
idee??
