Introduction:
Adding JavaScript to your WordPress site can enhance your site’s functionality and make it more interactive. However, adding JavaScript to specific pages in WordPress can be quite tricky, especially if you’re not familiar with coding. Fortunately, there is a simple solution to this problem: editing your functions.php file.

In this guide, I, a WordPress enthusiast, will walk you through the steps on how to use functions.php to add JavaScript to specific pages in WordPress. Regardless of your programming knowledge, you will be able to follow along and add JavaScript to your WordPress site.

Step One: Before you Begin
Before we proceed, it’s essential to take precautions. You must backup your existing functions file before making any changes, so you can avoid losing your data if anything goes wrong.

To do this, go to the “Appearance” tab in WordPress and click on the “Editor” option. From there, select the functions.php file and copy the entire contents. Paste it into a notepad or any other text editor. Save this as backup_functions.php in case you need to restore it.

Step Two: Editing functions.php
Now that you have backed up your functions.php file let’s move onto adding the code to include the Javascript to our WordPress page.

  1. Identify the specific page which needs Javascript and it’s ID on the dashboard.

  2. Open up the functions.php file and add the following code: 

function add_script() 
if (is_page(ID)) 
wp_enqueue_script('script-name', get_template_directory_uri() . '/js/script.js', array(), '1.0.0', true);


add_action('wp_enqueue_scripts', 'add_script');

In the above code, replace the ID with your chosen page’s ID and “script-name” with any name you’d like to give to your script.

  1. Save the changes made to the functions.php file. Now your JavaScript will be added to your WordPress page.

Step Three: Testing Your Addition
It’s essential to test your new addition to ensure it’s working correctly.

  1. Visit the page you added the JavaScript.

  2. Right-click on the page and click on “View Page Source”.

  3. Look for the script that you added.

If you see the script file, then congratulations! You have successfully added JavaScript to your specific WordPress page!

Conclusion:
As you can see, adding JavaScript to specific pages in WordPress is not that difficult. Using the functions.php file to add JavaScript is a simple and efficient way to do this. With the above-mentioned steps, you can easily add JavaScript to your WordPress site without the use of a plugin.
