Answer 1

You should use .prop for disabled:

$("#menuContinenti").prop('disabled', function () {
   return ! $(this).prop('disabled');
});

UPDATE: didn't realize the current property value is an argument to the function; this version is even cleaner:

$("#menuContinenti").prop('disabled', function (_, val) { return ! val; });

UPDATE: ES2015

$("#menuContinenti").prop("disabled", (_, val) => !val);
