How to address and correctly accept Ajax requests in Yii within a single action?

Question

JavaScript

Good afternoon, 1. There is a need to accept several Ajax requests

within the current action . In the case of a single request, everything is clear:

if (Yii::app()->request->isAjaxRequest)
    {
      $this->renderPartial('_loopAjax', // _loop
      [
        '_request'=>Yii::app()->request,
        'dataProvider'=>$dataProvider,
      ]);
      Yii::app()->end();
    }
    else
    {
      $this->render('index',
      [
        'dataProvider'=>$dataProvider,
      ]);
    }

How can this be implemented given that there can be several get and post requests?

2. And I’m also interested in the moment, if using Jquery Ajax I generate a content block depending on the menu item I poke on, is there a way to transfer authority to another action (or controller / action ) when displaying certain content, and not stay within the current one?

3. If 2. , then is there a way to go back to the current one?
