Question

我使用高级框架Yii2。我在前端有RegionController，在前端有Region模型。在视图中，我想用Select2调用公共功能Countrylist来显示所有国家/地区。但是当我尝试调用此函数时，异常是“找不到此页面”... 这是控制器：

这是我调用函数的视图代码：

    <?php

namespace frontend\controllers;

use Yii;
use frontend\models\Region;
use frontend\models\Country;
use frontend\models\RegionSearch;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\db\Query;
use yii\helpers\ArrayHelper;
use yii\helpers\Json;
/**
 * RegionController implements the CRUD actions for Region model.
 */
class RegionController extends Controller
{

    public function actionRegionlist($q = null, $id = null) {
        \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
        $out = ['results' => ['id' => '', 'text' => '']];
        if (!is_null($q)) {
            $query = new Query;
            $query->select('id, name AS text')
                ->from('region')
                ->where(['like', 'name', $q])
                ->andWhere(['country_id' => $_GET['country']])
                ->limit(20);
            $command = $query->createCommand();
            $data = $command->queryAll();
            $out['results'] = array_values($data);
        }
        elseif ($id > 0) {
            $out['results'][] = ['id' => $id, 'text' => Region::find($id)->name];
        }
        return $out;
    }

    public function actionCountrylist($q = null, $id = null) {
            \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
            $out = ['results' => ['id' => '', 'text' => '']];
            if (!is_null($q)) {
                $data = array();
                $arr = ArrayHelper::map(Country::find()->select('country.id, country.name')->filterWhere(['like', 'country.name', $q])->limit(10)->all(), 'id', 'name');
                ksort($arr);
                if ($arr) {
                    $k = 0;
                    foreach ($arr as $id => $value) {
                        $data[$k]['id'] = $id;
                        $data[$k]['text'] = $value;
                        $k++;
                    }
                }
                $out['results'] = array_values($data);
            }
            return $out;
    }
}

尝试根据范围更改网址

$url = \yii\helpers\Url::to(['region\countrylist']);

或

$url = \yii\helpers\Url::to(['\region\countrylist']);

使用Select2在视图Yii2中调用函数
