Hi Patrick,
To accomplish this, make a copy of /wp-content/plugins/the-events-calendar/resources/events.js and place in an ‘events’ folder in your theme. Then, open it up and comment out lines 14-19 which is the code for the tooltips in the big calendar. Then, add this to your themes functions.php file:
/*-------------------------------------------------------------------------------
Add Custom events.js
-------------------------------------------------------------------------------*/
function example_enqueue_scripts() {
wp_dequeue_script('tribe-events-calendar-script');
wp_register_script('custom-events-calendar-script', get_template_directory_uri().'/js/events.js'); // notice it's not the same script name as the original one, that's important - otherwise it re-enqueues the old version
wp_enqueue_script('custom-events-calendar-script');
}
add_action('wp_enqueue_scripts', 'example_enqueue_scripts');
That will remove the core events.js and load yours instead.
Please keep in mind that you will then be running your own modified copy of events.js and if we publish any updates to the plugin, you will need to manually merge those in to yuor customized version.
I hope this helps!
