I am pretty new in WordPress and I have the following doubt: I have to include JQuery into a theme and I am doing in this way:

I create the following function into functions.php theme file and I add it as action:

function load_java_scripts() {
    // Load FlexSlider JavaScript that handle the SlideShow:
    wp_enqueue_script('jQuery-js', 'http://code.jquery.com/jquery.js', array(), '1.0', true);
add_action('wp_enqueue_scripts', 'load_java_scripts');

So I think that I can add it as some other javascript or CSS local resources but I am not sure about this method because in this case the jquery.js is not a local resource but is an online resource (is the same thing?)

And I also have some doubts because searching online I have found some differents method to add JQuery to my theme, like this one: http://css-tricks.com/snippets/wordpress/include-jquery-in-wordpress-theme/

Can you give me some more precise information about how to correctly complete this task?



  • Why are you including an external copy of jquery? Is the included jquery library in WordPress not suitable for your uses?

When you register/enqueue your other scripts, simply pass jQuery as the third parameter and it will be loaded first and only once, from the local WordPress files:

wp_register_script( 'theme-js', get_template_directory_uri() . '/js/theme.js', array( 'jquery') );

If you only need the jQuery, simply use:


You can find a list here about the javascript libraries that are included in your default WordPress site:


  • mmm are you meaning that WP automatically load JQuery in some way and that I have not to manually load it but that I can only pass it as dependency of the other JavaScript that require it? Jan 21, 2014 at 11:41

    I mean jQuery is in WordPress by default, located in the wp-includes folder, so you don't need to use an external source to include the javascript file. You can find all of the libraries included in WordPress in the codex, i updated my answer with a link. Also worth to mention, that jQuery is in no-conflict mode, so instead of $(document).ready(function(){... you should start with jQuery(document).ready(function($){...
