Reply To: Ajax does not work when filtering cities in Dashboard

At LocationController.php

Remove getStatesData() and getCityData() and place below two mtehods instead of that

  public function getStatesData(){
        $searchTerm = \request('search.value');

        if ($searchTerm){
            $states = State::select('states.id', 'state_name', 'country_name', 'country_id')->leftJoin('countries', 'countries.id','=','states.country_id')->where('state_name', 'like', "%$searchTerm%");

        }else{
            $states = State::select('states.id', 'state_name', 'country_name', 'country_id')->leftJoin('countries', 'countries.id','=','states.country_id');

        }

        return Datatables::of($states)
            ->filterColumn('country_name', 'whereRaw', '1=1', [])
            ->addColumn('actions',function($state){
                $html = '<a href="'.route('edit_state', $state->id).'" class="btn btn-primary"><i class="fa fa-edit"></i> </a>';
                $html .= '<a href="javascript:;" data-id="'.$state->id.'" class="btn btn-danger deleteState"><i class="fa fa-trash"></i> </a>';
                return $html;
            })
            ->removeColumn('id', 'country_id')->make(true);
    }

And

    public function getCityData(){
        $searchTerm = \request('search.value');

        if ($searchTerm){
            $cities = City::select('cities.id', 'cities.city_name', 'states.state_name', 'cities.state_id', 'countries.country_name', 'states.country_id')->leftJoin('states', 'states.id', '=', 'cities.state_id')->leftJoin('countries', 'countries.id', '=', 'states.country_id')->where('cities.city_name', 'like', "%{$searchTerm}%")->orderBy('city_name', 'asc');
        }else {
            $cities = City::select('cities.id', 'cities.city_name', 'states.state_name', 'cities.state_id', 'countries.country_name', 'states.country_id')->leftJoin('states', 'states.id', '=', 'cities.state_id')->leftJoin('countries', 'countries.id', '=', 'states.country_id')->orderBy('city_name', 'asc');
        }

        return Datatables::of($cities)
            ->filterColumn('state_name', 'whereRaw', '1=1', [])
            ->filterColumn('country_name', 'whereRaw', '1=1', [])
            ->addColumn('actions',function($city){
                $html = '<a href="'.route('edit_city', $city->id).'" class="btn btn-primary"><i class="fa fa-edit"></i> </a>';
                $html .= '<a href="javascript:;" data-id="'.$city->id.'" class="btn btn-danger deleteCity"><i class="fa fa-trash"></i> </a>';
                return $html;
            })
            ->removeColumn('id', 'state_id','country_id')->make(true);
    }

Hopefully, your issue will be solved
