How to Add Custom JavaScript to Your WordPress Website

Adding custom JavaScript to your WordPress website can be a powerful way to extend its functionality and enhance the user experience. Whether you want to add a custom script for a specific feature or simply make some small tweaks to the way your website works, you’ll need to know how to add JavaScript to your WordPress site to make it happen.

In this post, we’ll show you 3 different methods you can use to add custom JavaScript to your WordPress website in a few simple steps.

Prerequisites

Before we get started, there are a few things you’ll need:

• A WordPress website
• Access to the WordPress dashboard
• Basic knowledge of HTML and JavaScript

Method 1: Using a Plugin

The easiest way to add custom JavaScript to your WordPress website is by using a plugin. There are several plugins available that allow you to easily add custom scripts to your site without the need to edit any code.

Here are a few popular plugins that you can use:

• Insert Headers and Footers
• Custom JS
• Simple Custom CSS and JS

To use these plugins, simply install and activate them from the WordPress plugin repository. Once activated, you can go to the plugin’s settings page and add your custom JavaScript code. The plugin will then automatically add the script to your website’s header or footer, depending on the plugin’s settings.

However, if you don’t want to add unnecessary plugins to your WordPress website, you can follow one of the next methods to add the Javascript code to your WordPress website without installing new plugins.

Method 2: Editing the Functions.php File

Another way to add custom JavaScript to your WordPress website is by editing the functions.php file of your theme. This method is slightly more advanced and requires some coding knowledge, but it can be useful if you want to add a script that is specific to your theme.

To add custom JavaScript to your WordPress site using the functions.php file, follow these steps:

1. Log in to your WordPress dashboard and go to Appearance > Themes.
2. From the theme editor, click on the functions.php file in the right-hand menu.
3. Add your custom JavaScript code to the file. It’s generally a good idea to wrap the code in a script tag, like this:

function custom_javascript() {
  ?>
  <script>
    // Your custom JavaScript code goes here
  </script>
  <?php
}
add_action( 'wp_footer', 'custom_javascript' );

4. Save the functions.php file and upload it to your website.

Your custom JavaScript code should now be added to your WordPress website.

If for some reason you can’t access the functions.php file or your code doesn’t work that way, you can try the following method to add your custom Javascript code to your WordPress website.

Method 3: Using the WordPress Customizer

If you don’t want to install a plugin or edit code, you can also add custom JavaScript to your WordPress site using the built-in WordPress Customizer. This method is quick and easy, but it’s only suitable for small snippets of JavaScript code.

To add custom JavaScript to your WordPress website using the Customizer, follow these steps:

1. Log in to your WordPress dashboard and go to Appearance > Customize.
2. From the Customizer menu, click on the Additional CSS option.
3. In the CSS editor, add your custom JavaScript code. Make sure to wrap it in a script tag
4. Click the Publish button to save your changes.

Your custom JavaScript code should now be added to your WordPress website.

Conclusion

Adding custom JavaScript to your WordPress website can be a great way to extend its functionality and improve the user experience. Whether you use a plugin, edit the functions.php file, or use the WordPress Customizer, there are several easy ways to add custom JavaScript to your site.
