Question

Ich möchte dafür sorgen, dass, wenn ich auf eines der Dropdown-Menüs klicke, sofort der Wert angezeigt wird, der auf der Datensatz-ID aus der zugehörigen Tabelle basiert. Ich möchte dafür sorgen, dass beim Klicken auf eines der Dropdown-Menüs sofort ein Wert angezeigt wird, der auf der Datensatz-ID aus der zugehörigen Tabelle basiert. Wenn „golongan“ ausgewählt wird, erscheint automatisch der Wert von „gaji pokok“. Wenn „Asisten Ahli“ ausgewählt ist, erscheint automatisch der Wert für „Tunjangan Fungsional“. Wenn „Assistent des Vorsitzenden | Expertenassistent“ ausgewählt wird, wird automatisch der Wert „Strukturzulage“ angezeigt.

Wie verwende ich Javascript onChange zum Verpacken in Laravel?

抱歉，我不太懂你的语言，但你可以用 jquery 做这样的事情

<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>

您可以将依赖下拉列表保留为空，然后通过ajax获取这些依赖下拉列表，如下所示：

<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>

并在ajax中声明你将在url中调用的路由

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

在控制器中执行如下操作：

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);
}
