Login throttles in laravel 5.1 with ajax - laravel

Question

I'm working on a login form which uses ajax and I can't setup login throttling.
ThrottlesLogins trait redirects somewhere but I don't need that. How can I return number of seconds when user fails password n times?
Controller:
<?php
namespace App\Http\Controllers\Login;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
use Auth;
class LoginController extends Controller
{
use AuthenticatesAndRegistersUsers, ThrottlesLogins;
public function index()
{
if (Auth::check()) return redirect(url('/dashboard'));
else return view('admin.login');
}
public function login(Request $request) {
$this->validate($request, [
'username' => 'required', 'password' => 'required',
]);
$credentials = $request->only('username', 'password');
$throttles = $this->isUsingThrottlesLoginsTrait();
if ($throttles && $this->hasTooManyLoginAttempts($request)) {
return $this->sendLockoutResponse($request);
}
if (Auth::attempt($credentials, $request->has('remember')))
{
return $this->handleUserWasAuthenticated($request, $throttles);
//return response()->json(['code' => 1, 'redirect' => url('/dashboard')]);
}
//else return response()->json(['code' => 0]);
if ($throttles) {
$this->incrementLoginAttempts($request);
}
}
}
routes.php
/* Login */
Route::group(array('prefix' => 'login', 'namespace' => 'Login', 'middleware' => 'guest'), function() {
Route::get('/', 'LoginController#index');
Route::post('/', 'LoginController#login');
});

You can change:
if ($throttles && $this->hasTooManyLoginAttempts($request)) {
return $this->sendLockoutResponse($request);
}
into
if ($throttles && $this->hasTooManyLoginAttempts($request)) {
if ($request->ajax()) {
return response()->json(['lockout_time' => $this->lockoutTime()]);
}
else {
return $this->sendLockoutResponse($request);
}
}
