Top ↑ Default Scripts and JS Libraries Included and Registered by WordPressīy default, WordPress installation includes many popular javascript libraries and scripts commonly used by web developers besides the scripts used by WordPress itself. Uses global: ( unknown type) $wp_scripts.Uses: WP_Scripts::add(), WP_Scripts::add_data() and WP_Scripts::enqueue().This is useful to keep in mind when debugging ancient themes. This means that it may not work with a few very old themes that do not call these functions. This function relies on the use of wp_head() and wp_footer() by the active theme.

jQuery UI Effects is not included with the jquery-ui-core handle.Instead, use wp_deregister_script() and register the script again with the new parameters. If you try to register or enqueue an already registered handle with different parameters, the new parameters will be ignored.

Calling it outside of an action hook can lead to problems, see the ticket #11526 for details. For the login screen, use the login_enqueue_scripts action hook. To call it on the administration screens, use the admin_enqueue_scripts action hook.
