Jquery ajax下拉列表不在laravel中显示数据城市

我在下拉列表城市中使用ajax时遇到了一些限制。单击“省”部分时，它不会显示城市数据

Regency.php

    namespace App;

use Illuminate\Database\Eloquent\Model;
use RajaOngkir;

class Regency extends Model
{
    protected $fillable = ['id', 'province_id', 'name'];

    public static function populate() {
        foreach (RajaOngkir::Kota()->all() as $kota) {
            $model = static::firstOrNew(['id' => $kota['city_id']]);
            $model->province_id = $kota['province_id'];
            $model->name = $kota['type'] . ' ' . $kota['city_name'];
            $model->save();
        }
    }

    public function province()
    {
        return $this->belongsTo('App\Province');
    }
}

Province.php

    namespace App;

use RajaOngkir;
use Illuminate\Database\Eloquent\Model;

class Province extends Model
{
    protected $fillable = ['id', 'name'];

    public static function populate() {
        foreach (RajaOngkir::Provinsi()->all() as $province) {
            $model = static::firstOrNew(['id' => $province['province_id']]);
            $model->name = $province['province'];
            $model->save();
        }
    }
}

AddressController.php

    namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class AddressController extends Controller

    public function regencies(Request $request)
    {
        $this->validate($request, [
            'province_id' => 'required|exists:provinces,id'
        ]);

        return Regency::where('province_id', $request->get('province_id'))
            ->get();
    }

路线

试试这个

首先，在

$中添加
类型
。ajax

type: "post"

然后在路线中将

get

更改为

post

Route::post('checkout/address/regencies', 'AddressController@regencies');

---

您的路线是

签出/地址/摄政

，但您请求

/address/摄政

。这就是为什么会出现

404

错误

在ajax中更改url

url: '/checkout/address/regencies?province_id=' + value,

---

原谅我，我在路上不小心。非常感谢你帮助我。。最好的先生。

Route::post('checkout/address/regencies', 'AddressController@regencies');

url: '/checkout/address/regencies?province_id=' + value,
