AJAX response with HTML code in Yii2?

Question

Yii

Lord.
In yii2 - newbie and first problem.
I implement a simple ajax search - on the keyup event, a request is made to the controller-> BD and then in the controller in a loop, I write data to HTML tags that I store in one variable, like $response.=''
Then I return this variable and insert it into the desired block on site.
Everything works, except for the Modal::begin(); widget;
I can't write the modal code to a variable and that's the problem. Not all HTML is displayed, but only the button of the modal window.
I understand that this is the most crooked implementation, but there is really little experience in this framework.

Answer 1

Specifically in your case

ob_start(); 
     Modal::begin();
echo 'contnetn';
Modal::end();
    ob_start(); 

$out .= ob_get_clean();

or add a view and write your code there. But all this is wrong. But teach! 1) Json response. 2) renderAjax() 3) renderPartial()

Answer 2

In your Action that processes ajax, return the desired view , just don't forget to create this view, and in ajax in response, catch this html and paste it where you need it, if very briefly)
