I made a filter in laravel and it works perfectly but nevertheless it brings all the cities. It does not bring the specific cities of that state. I do not know if this filter has to go there in the laravel controller, how does it work for jquery? I'm using a Rest-Full web-service

I'm passing in the postman as follows: link

It returns me all states:

I do not do it in Laravel 5.2

View

<script type="text/javascript">
$('select[name=uf]').change(function () {
    var uf = $(this).val();
    $.get('/logistica/get-cidades/' + uf, function (busca) {
        $('select[id=comarca_id]').empty();
            $('select[id=comarca_id]').append('<option value=""> </option>');
        $.each(busca, function (key, value) {
            $('select[id=comarca_id]').append('<option value="' + value.id + '">' + value.name + '</option>');
        });
    });
});

Route

Route::get('/get-cidades/{uf}', [
    'middleware' => 'auth',
    'uses' => 'ExecucaoController@get_cidades'
    ]);

Note: remember that on the route I use a "logistical" prefix.

Controller

public function get_cidades($id)
{
    $comarca = DB::table('cidades')
      ->where('uf','=', $id)
      ->orderBy('name','asc')
      ->get();

    return Response::json($comarca);
}
