Question

I have an AJAX form which is validated by AJAX callback function. Everything is done using Drupal API. But I don’t want to use standard mechanism of appending/prepending/replacing of DOM elements when callback happens. How to catch that AJAX response and react on it with my custom function?

Answer 1

You can try defining a behavior. In many situations, including an AJAX request, Drupal will call to “attachBehaviors” that will trigger your behavior too:

Drupal.behaviors.mybehavior = {
  attach: function (context, settings) {

          console.log(context);    


  }
};

You must check and inspect context to know if it’s the right context what are you looking for
