I am trying to learn WP theme development. And I just learned that WP already has a jQuery version included. Until now I have been using the jQuery from Google's CDN.

So I just now deleted the CDN link from my code. And of course all my jQuery code stopped working.

So I guess I am missing something. What do I need to do if I want to use WordPress's local jQuery?

When I search SE QA and Google all I can find is how to un-register the local jQuery version and then register CDN. But that is not what I want to do. I want to use the local jQuery.

So what am I missing?

  • search WPSE before you ask a question. It's great possibility that it has been answered already. wordpress.stackexchange.com/a/111569

  • Well I did search first. And I also said I already been searching in my Question. And all I could find was how to deregister and that was not what I was trying to do :)

WP's jQuery is not mapped to $ like you may expect, it is loaded in noConflict mode so you'll need to use jQuery() instead of $(), unless you map it yourself.

When you include your js file you'll want to make sure to set jQuery as a dependency as well:

wp_enqueue_script( 'your-script-handle', get_stylesheet_directory_uri() . '/js/your-script.js', array( 'jquery' ), '1.0.0' );

In order to enqueue jQuery from WP-installation you can:

function custom_enqueue_scripts() {
    // Jquery enqueue

add_action('wp_enqueue_scripts', 'custom_enqueue_scripts');

Additionally, using this trick you can enqueue jQuery into footer (wp_footer)

function custom_enqueue_scripts() {
    // Jquery - to the footer of template
    wp_register_script('jquery', includes_url('/js/jquery/jquery.js'), false, NULL, true);

add_action('wp_enqueue_scripts', 'custom_enqueue_scripts');


Expanding the answer.

Using wp_register_script you can register your custom scripts. After, they can be wp_enqueue_script by the $handler.

Generally it grant a benefit of code length reduction [Related Answer], but I'd like to emphasize your attention on WordPress pre-registered scripts (local in your meaning).

Visit this Codex Page [Handles and Their Script Paths Registered by WordPress]. There you will find a $handler's for jQuery UI and other usefull stuff, that you can enqueue as on example above.
