wordpress - WP: how to remove version number in wp_enqueue_script?

Question

I'm trying to remove the version number from appearing in the URL generated by wp_enqueue_script. It seems like I should pass a null on the 4th parameter per http://codex.wordpress.org/Function_Reference/wp_enqueue_script:

wp_enqueue_script('jquery', false, array(), null, false);

It's not working. I still see the version number. How do I remove that?

Also, how do I use wp_enqueue_script so that I get jQuery from the Google CDN?

Answer 1

You can either use

wp_enqueue_script('jquery', 'URL', array(), '', false);

or

wp_enqueue_script('jquery', 'URL', array(), null, false);

or you can put a generic name placeholder

wp_enqueue_script('jquery', 'URL', array(), 'custom', false);

But particularly with "jquery" I would deregister the default if you want to replace it

wp_deregister_script('jquery');
$GoogleJqueryURI = 'http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js';
wp_register_script('jquery', $GoogleJqueryURI, array(), 'custom', false);
wp_enqueue_script('jquery');
