how to call JavaScript from controllers in yii2

Question

in my research I found that one can use this method:

$this->registerJsFile()

However, when I use it I get this error:

Calling unknown method: frontend\controllers\AvailableController::registerJs()

You should follow MVC design pattern, js is related to views — soju

The method:

registerJs($url, $options = [], $key = null)

is defined in the yii2/web/View class. The $this object in your example is an instance of your AvailableController class, that presumably extends the Controller class. That's why you get the error.
You should use the $this object of one of your views.
Try to go to to your views/available folder, open a view there (for example, view.php), identify your $this object, and call registerJs() from there.
