Possible to populate the modal window with content for a post (clicked link)?

I have a page of blog post links and when I click one instead of going to a permalink and to a single.php template I would like it to open the post in a modal window with a close button like the contact form window.

How do I capture and pass the post ID from the link to the modal window so that I can show the correct post content?

BTW I am using the loop below to display the links on the original page.

[code]

<div class="cd-projects-wrapper"> <ul class="cd-slider"> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <li class="current"> <a href='#'> <img src='/portfolio/assets/img.png' alt='project image'> <div class='project-info'> <h2><a href="#" class="link" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2> <p>Description of project <?php echo $post_id; ?></p> </div> </a> </li>

        <?php endwhile;endif; ?>

    </ul> <!-- .cd-slider-navigation -->
</div> <!-- .cd-projects-wrapper -->

[/code]
