yii2:行为简单实例

yii2:行为

行为是 yiibaseBehavior 或其子类的实例。

就是:将一个类的属性和方法,赋给另一个类使用。

例如:

behavior

namespace app\components\behavior;
use yii\base\Behavior;
 
class MyBehavior extends Behavior{
 
    public $name;
    public $age;
 
    public function setName($name)
    {
        $this->name = $name;
    }
 
    public function getName()
    {
        return $this->name;
    }
 
    public function setAge($age)
    {
        $this->age = $age;
    }
 
    public function getAge()
    {
        return $this->age;
    }
}

然后controller中使用:

namespace app\modules\demo\controllers;
 
use Yii;
use app\models\DCountry;
use yii\web\Controller;
use app\components\behavior\MyBehavior;
 
//use app\compon
/**
 * Default controller for the `demo` module
 */
class DefaultController extends Controller
{
 
    public $url;
 
    public function behaviors()
    {
        return [   
             // 匿名行为,只有行为类名
            'MyBehavior'=>[
                'class'=>MyBehavior::className(),      
                'name'=>'jerry',
                'age'=>20    
            ]
 
        ];
    }
 
    
 
    /**
     * Renders the index view for the module
     * @return string
     */
    public function actionIndex()
    {         
 
 
        return $this->render('index', ['age'=>$this->age, 'name'=>$this->name]);
    }
}
