Calling do_shortcode in wp_localize_script strips output

I am working on adding some functionality on a WordPress plugin which after a certain click needs to call on some shortcode through ajax.

What I first attempted was to call the shortcode inside of the ajax processing in my functions.php file:

add_action( ‘wp_ajax_nopriv_showads’, ‘showads’ );

function showads(){

echo do_shortcode(‘[myshortcode]’);

wp_die();
}
Where I would move the output of the shortcode in the response of the ajax call. This shortcode did not execute at all.

So instead after some research in the “wp_localize_script” function inside of the plugin I would call the shortcode:

wp_localize_script( ‘script-handle’, ‘ajax_object’,
array(‘ajaxurl’ => admin_url( ‘admin-ajax.php’ ),
‘adspace’ => do_shortcode( ‘[myshortcode]’ )
));
And in the response of the ajax I would move the output of the shortcode.

The problem I’m having at the moment is that as soon as the “wp_localize_script” function is called the output of the shortcode (it should create a google ad) is all stripped.

I’d like to know if there is a way to not have the shortcode output stripped or advice if I’m trying to solve this whole thing the incorrect way.
