Pilih OnChange Javascript pada Laravel

Question

Saya ingin membuatnya supaya apabila saya mengklik pada salah satu menu lungsur, nilai berdasarkan ID rekod daripada jadual berkaitan segera muncul. Saya ingin membuatnya supaya apabila saya mengklik pada salah satu lungsur turun, nilai berdasarkan ID rekod daripada jadual berkaitan muncul serta-merta. Apabila "golongan" dipilih, nilai "gaji pokok" muncul secara automatik. Apabila "asisten ahli" dipilih, nilai untuk "tunjangan fungsional" muncul secara automatik. Apabila "Pembantu Pengerusi | Pembantu Pakar" dipilih, nilai "Elaun Struktur" muncul secara automatik.

Bagaimana untuk menggunakan Javascript onChange untuk pembungkusan dalam laravel?

Answer 1

Maaf, saya tidak begitu memahami bahasa anda, tetapi anda boleh melakukan sesuatu seperti ini dengan jquery

<div class="form-group mb-3">
        <select  id="country-dropdown" class="form-control">
            <option value="">-- Select Country --</option>
            @foreach ($countries as $data)
            <option value="{{$data->id}}">
                {{$data->name}}
            </option>
            @endforeach
        </select>
    </div>
    <div class="form-group mb-3">
        <select id="state-dropdown" class="form-control">
        </select>
    </div>
    <div class="form-group">
        <select id="city-dropdown" class="form-control">
        </select>
    </div>

Anda boleh membiarkan dropdown dependency kosong dan kemudian dapatkan dropdown dependency ini melalui ajax seperti ini:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
    $(document).ready(function () {

        /*------------------------------------------
        --------------------------------------------
        Country Dropdown Change Event
        --------------------------------------------
        --------------------------------------------*/
        $('#country-dropdown').on('change', function () {
            var idCountry = this.value;
            $("#state-dropdown").html('');
            $.ajax({
                url: "{{url('api/fetch-states')}}",
                type: "POST",
                data: {
                    country_id: idCountry,
                    _token: '{{csrf_token()}}'
                },
                dataType: 'json',
                success: function (result) {
                    $('#state-dropdown').html('<option value="">-- Select State --</option>');
                    $.each(result.states, function (key, value) {
                        $("#state-dropdown").append('<option value="' + value
                            .id + '">' + value.name + '</option>');
                    });
                    $('#city-dropdown').html('<option value="">-- Select City --</option>');
                }
            });
        });

        /*------------------------------------------
        --------------------------------------------
        State Dropdown Change Event
        --------------------------------------------
        --------------------------------------------*/
        $('#state-dropdown').on('change', function () {
            var idState = this.value;
            $("#city-dropdown").html('');
            $.ajax({
                url: "{{url('api/fetch-cities')}}",
                type: "POST",
                data: {
                    state_id: idState,
                    _token: '{{csrf_token()}}'
                },
                dataType: 'json',
                success: function (res) {
                    $('#city-dropdown').html('<option value="">-- Select City --</option>');
                    $.each(res.cities, function (key, value) {
                        $("#city-dropdown").append('<option value="' + value
                            .id + '">' + value.name + '</option>');
                    });
                }
            });
        });

    });
</script>

dan isytiharkan dalam ajax laluan yang anda akan panggil dalam url

Route::post('etch-states', [DropdownController::class, 
'fetchState']);
Route::post('fetch-cities', [DropdownController::class, 'fetchCity']);

Lakukan operasi berikut dalam pengawal:

public function fetchState(Request $request)
{
    $data['states'] = State::where("country_id", $request->country_id)
                            ->get(["name", "id"]);

    return response()->json($data);
}
/**
 * Write code on Method
 *
 * @return response()
 */
public function fetchCity(Request $request)
{
    $data['cities'] = City::where("state_id", $request->state_id)
                                ->get(["name", "id"]);
                                  
    return response()->json($data);
}
