How to add Jquery to content page ?

Hello,

I’m trying to add the following text animation to my frontpage :
https://unwrongest.com/projects/airport/

I’ve downloaded from the page above the jquery.airport-1.1.source.js file and transfered it to mytheme/js Folder

I’ve added the wp_enqueue_script to functions.php file :

function my_init() {
	if (!is_admin()) {
		// comment out the next two lines to load the local copy of jQuery
		wp_deregister_script('jquery');
		wp_register_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js', false, '1.3.2');
		wp_enqueue_script('jquery');
	}
}
add_action('init', 'airport');

Now, It’s not clear to me if I have to add the code below (taken from from the link above) on my content page in the backend :

jQuery(function ($) {
	$(  element  ).airport([ 'moscow', 'berlin', 'stockholm' ]);

If so, I’m doing something wrong as it is not working.

Some suggestions would be very helpful.
Thank you for your time.
