wp_query with ajax

So, i found a work around for this . I just display the excerpt() and then I link them to the permalink() of this post.

// to load the result from ajax

function filter_post_asb_clone()
{
    // ob_start();
    $args = array(
        'year' => $_POST['year'] ,
        'cat' => array(42 , 43)
    );
    $query = new WP_Query($args);
    if ( $query -> have_posts()) :
?>
    <div class="container">
        <ul class="display-posts-listing">
            <?php while($query -> have_posts()) : $query -> the_post(); ?>
            <a href="https://wordpress.stackexchange.com/questions/328651/<?php echo the_permalink(); ?>">
                <li class="listing-item">
                <h4><?php the_title();?></h4>
                <?php
                    echo the_excerpt();
                ?>
                <?php the_post_thumbnail();?>
               </li>
            </a>
            <?php endwhile ; ?>
            <?php wp_reset_postdata();?>
        </ul>
    </div>
<?php
    endif;
    exit;
}

Thank you very much
