How to enqueue script based on post category?

I have scripts for various little tools I have made using some js and html. I want the js to load only on specific single posts in side a specific category. I have tried the following code and it does not work. I removed the “if” statement and the script does run and work so it’s a matter of fixing the if statement.

Here’s what I’ve got so far,

    if ( is_single() && in_category( 'mouse' ) ) {
wp_enqueue_script( 'mousescript');
}

Thank you very much for any and all help, it’s greatly appreciated!

Inside your theme’s functions.php add something like this:

function my_conditional_enqueue_script() {
    global $post;
    if (is_single($post->ID) && in_category('mouse', $post->ID)) {
        wp_enqueue_script('mousescript');
    }
}
add_action('wp_enqueue_scripts', 'my_conditional_enqueue_script');

Also, make sure you use wp_register_script before you attempt to enqueue.
