[wp-hackers] wp_enqueue_script() and URLs with 2+ parameters

[Glenn Ansley]

Hi Mike,
I've done this before, but I don't have the code anymore because the
project was scratched (i'm an idiot for deleting code)

Maybe I can point you in the right direction though...
* There is a function in wp-includes/formatting.php called clean_url
* To make a long story short, wp_enqueue_script runs your src through
that before spitting it out.
* Luckily, there is a filter on the return and the original url is
preserved at the top of the clean_url() function.
* First, you will have to hook into that filter (remember to ask for
more than the 1 default accepted arg: <?php add_filter($tag,
$function_to_add,  $priority = 10,  $accepted_args = 1); ?>)
* Second, you will have to determine if it's filtering you're src (do
strpos() or something)
* If you get a match, return the original rather than the clean url.

Something like that... let me know if you have trouble.
