Filters the response from rendering the partials.


apply_filters( 'customize_render_partials_response', (array) $response, (WP_Customize_Selective_Refresh) $instance, (array) $partials ); 

Plugins may use this filter to inject $scripts and $styles,, which are dependencies for the partials being rendered. The response data will be available to the client via the render-partials-response JS event, so the client can then inject the scripts and styles into the DOM if they have not already been enqueued there.

If plugins do this, they'll need to take care for any scripts that do document.write() and make sure that these are not injected, or else to override the function to no-op, or else the page will be destroyed.

Plugins should be aware that $scripts and $styles, may eventually be included by default in the response.

  4. return $response
  5. }; 
  7. // add the filter
