I am reading through the developer site for Wordpress and am just at the beginning of my learning of it. I have gotten my CSS to work via the wp_enqueue_style() but my javascript won't work via the wp_enqueue_script().

I have not added any Javascript on the pages themselves, I have the functions.php file with the wp_enqueue_script() in it which points to my /js/functions.js file where I want the toggleNav() function to work in for displaying the navigation menu differently on mobile.

What am I doing wrong? Here is my code:



   function my_theme_scripts(){
   wp_enqueue_style( 'style', get_stylesheet_uri() );

   wp_enqueue_script( 'functions', get_template_directory_uri() . 
   'js/functions.js', array(), '1.1', true );

   add_action( 'wp_enqueue_scripts', 'my_theme_scripts' );



 function toggleNav() {
            var nav = document.getElementById("navbar");
            if (!nav.style.display || nav.style.display === "none") {
                nav.style.display = "block";
            } else {
                nav.style.display = "none";


I've even tried placing a function call in the footer.php but it doesn't work. When I add the javascript directly into the footer.php file it does work though.

Edit: Console output (I don't mind the images not being found as I'm just wondering about the js right now)enter image description here

  • did you check js file is enqueued properly or not ? can you see functions.js in view source ? Jun 20, 2019 at 11:29
  • In the source there is the following in the head (but I think it might be from the wp_head(), not sure): <script type="text/javascript"> window._wpemojiSettings =... </script> (I didn't add the whole script as it's too long for the comments)

    please check in your header.php have wp_head(); AND in footer.php have wp_footer(); ? Jun 20, 2019 at 12:20

You must have to include wp_head() in header.php and wp_footer(); in your footer.php


<!DOCTYPE html>
<html lang="en">
  <meta charset="UTF-8">


 <?php wp_footer();?>

if you do not add wp_head() AND wp_footer() Wordpress hook does not fire using wp_enqueue_scripts hook .
