 You're actually not invoking the JavaScript, you're loading it again and
 again. Passing multiple arguments to a script can be done in a more
 effective way from another script or number of scripts.

 query string ( such as when it matches the $src parameter, as in my
 example) then the API doesn't work as expected... the value of null for
 $ver is ignored.

 The `handle` is the internal name of the script. It supports URL query
 type syntax as a not recommended back-compat only. Anything passed after
 the `?` in a script handle is treated (and outputted) as cache busting URL
 query.

 Btw, perhaps it's time to remove that back-compat bit from script handles.
 It was a back-compat even 5 years ago. Think it's a left over from before
 WP_Scripts supported explicit cache-busting arg.

 Trying to guess what you want to do: load the same script multiple times
 with different query strings (quite ineffective as the script will be
 fully loaded each time). The needed query string can be in `$src` and a
 `static` in your shortcode handling function can be used to make the
 handle unique:
 {{{
 function _my_shortcode_handler() {
   static $number = 1;

   wp_enqueue_script( 'my-script-' . $number, $src, array("jquery"), ... );
   $number++;
 }
 }}}

 Suggesting closing as invalid.
