Enqueuing Scripts In Functions.php
wp_enqueue_script helps add JavaScript to a WordPress site. It’s a built-in function. It ensures scripts load properly. This is important for site performance. The function needs two main things: script name and file path.
Link the JavaScript file correctly. Use the get_stylesheet_directory_uri function. This points to the child theme folder. Add the file path after it. The code should look like this:
function my_theme_enqueue_scripts() {
wp_enqueue_script('my-script', get_stylesheet_directory_uri() . '/js/my-script.js', array(), null, true);
}
add_action('wp_enqueue_scripts', 'my_theme_enqueue_scripts');

Testing The Javascript Integration
Integrating JavaScript into a WordPress child theme enhances functionality. Add the JavaScript file by using the `wp_enqueue_script` function in the theme’s `functions. php` file. This method ensures proper loading and compatibility with your website.
Verifying Script Loading
Check if the JavaScript file loads correctly. Open your website. Use the browser’s developer tools. Look for the console tab. It shows errors. Errors mean the file isn’t loading. Also, check the network tab. It lists all files loaded on the page. Your JavaScript file should be there. Ensure the path is correct. A wrong path stops loading.
Troubleshooting Common Issues
Sometimes scripts don’t work. Check your syntax. A small mistake can cause problems. Another issue is file location. Files must be in the right place. Check permissions. Files need permission to load. Ensure your child theme is active. Inactive themes don’t load scripts. Finally, test on different browsers. Some browsers might block scripts.
