How to get the cookie value of number of favorites ?

Hi,

I get the number of favorites in javascript and show it in navigation.
So each clic increase or decrease the total.

But I sometime get weird results. For exemple, after one day, total is different from the number of favorite shown by the_user_favorites_list().

Configuration: anonymous users et cookies.

I get results with this script :

<script type=”text/javascript”>var count = <?php echo the_user_favorites_count();?></script>
<span class=”compteur”><?php the_total_favorites_count(); ?></span>

Updating it with:

jQuery(document).on(‘favorites-updated-single’, function(event, favorites, post_id, site_id, status){
if (status == ‘active’) {count++;}
else {count–;}
jQuery(‘.compteur’).text(count);
});

Did i miss something?
Is there a way to get the cookie value of the total of favorites?

Thanks
