wp_dequeue_script page speed help

  • I have created a custom wp_dequeue script function in my functions.php, some of the dequeues work fine but others are simply ignored, i have cut the example code down to only include some of those that are not working:

    add_action('wp_enqueue_scripts','custom_conditional_loading');  

function custom_conditional_loading(){
	
	wp_dequeue_script('jquery-ui-core');
	wp_dequeue_script('moment-js');
	wp_dequeue_script('moment-core-js');
 if(! is_page(825))
   {
	
	 wp_enqueue_script('jquery-ui-core');
	 wp_enqueue_script('moment-js');
	 wp_enqueue_script('moment-core-js');
   }
}

    I am really trying to improve the performance on the website and there are a lot of unnecessary files being loaded, am I doing this wrong?

  • HI there.

    Take a quick look at the docs, you need to use a different action and add a priority to ensure it runs after your script is enqueued but before the script is actually printed.

    Thanks for the guidance, I have updated my code:

    add_action('wp_print_scripts','custom_conditional_loading', 100 );    

function custom_conditional_loading(){

   if(!is_page(825))
   {
	 wp_dequeue_script('jquery-ui-core');
	 wp_dequeue_script('moment-js');
	 wp_dequeue_script('moment-core-js');
   }
}

    But still no luck, I can deregister the scripts, but then they won’t load on the pages they are supposed to, I even tried copying and pasting the example you gave above and this didn’t work either, any ideas?
    thanks

    If you can deregister them then use is_page there.

    I tried to deregister and then register on a specific page using is_page but it didn’t register them?
