Plugin for custom action (on database)

Questions

I’m trying to develop a plugin that will perform a very simple database action. For now the plugin puts an option on the card sidemenu that, upon selection, tries to show some data thru a javascript popup. (I’m past the problem of trying to use “onclick=” and implemented a listener instead).
But when I click, nothing happens. What I can say is that the function is not being called.

Of course, I must be doing something wrong, but I really need this functionality for my project, so I’ll be very thankful for any help on this.

Your script does nothing but call the controller with the task ID. Why not do it directly from the template?

<li>
    <?= $this->url->icon('info-circle', t('Show Task Details'), 'TaskConnectController', 'show', array('task_id' => $task['id'])) ?>
</li>

In case you still want to use the script, I’d recommend using jQuery.

$(function () {
    $('.task-connect-info').click(function(e){
        e.preventDefault();
        // ...
    })
}
