infinite scroll manual trigger

Question

Just doesn't seem to work... :-( Have seen more complaints about it but I can't find the answer.

The Problem: Infinite scroll works but not the manual trigger. When I click the link, nothing happens. Firebug gives

Infinite Scroll

My code:

    <?php echo ('<ul id="infinite">'); ?>
<?php 
$wp_query = new WP_Query();
$wp_query->query('paged='.$paged.'&cat=5&showposts=3&meta_key=video_video&orderby=meta_value&order=ASC'  . $post->ID);
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<?php if ( get_post_meta($post->ID, 'video_video', true) ) : ?>
    <li class="video"><?php $home = array("h" => 290, "w" => 380, "zc" => 1, "q" =>100);
            //echo get('video_video');
            echo ('With: ');
            echo get('participant_first_name');
            echo ('&nbsp;');
            echo get('participant_last_name');
            echo ('</li>');?>

<?php endif;?>


<?php endwhile;?>

<?php if (get_post_meta($post->ID, 'video_video', true) ) { ?>
    <?php if ($wp_query->max_num_pages > 1) : ?>
        <nav id="nav-below" >
        <div id="next" >
        <?php next_posts_link( __( 'Scroll down for more', 'intowntheme' ) ); ?></div>
        </nav>
    <?php endif; //end nav ?>
<?php } else {  ?>
<p>There are no interviews at the moment </p>
<?php }   ?>     
</ul>     

And my script:

jQuery('ul#infinite').infinitescroll({ 
    navSelector  : "#next",  // selector for the paged navigation (it will be hidden)
    nextSelector : "#next a",   // selector for the NEXT link (to page 2)
    itemSelector : "ul#infinite li",  // selector for all items you'll retrieve
    errorCallback: function() { 
          // fade out the error message after 2 seconds
          $('#infscr-loading').animate({opacity: 0.8},2000).fadeOut('normal');   
        },   
    loading         : {
         msgText: "<em>Loading the next year of Grantees...</em>",
        finishedMsg: "<em>You've reached the end of the Interviews.</em>"
    },
  });

  //kill scroll binding
    jQuery(window).unbind('.infscr');
    //setTimeout("jQuery('#next').slideDown();", 1000);
     //hook up the manual click guy.

    jQuery('#next a').click(function(){
        jQuery('#next a').infinitescroll('retrieve.infscr');
     return false;
    });

also tried

jQuery(document).trigger('retrieve.infscr');

instead of

jQuery('#next a').infinitescroll('retrieve.infscr');

but no luck.

Firebug then says trigger(retrieve.infscr) called incorrectly

Pfoe, found it... Long live good documentation (NOT with this plugin!)

This:

 jQuery('#next a').click(function(){
    jQuery('#next a').infinitescroll('retrieve.infscr');
 return false;
});

Should be:

jQuery('#next a').click(function(){
    jQuery('ul#infinite').infinitescroll('retrieve');
 return false;
});

the biggest problem was the .infscr which shouldn't be there.. Hope it helps someone else..

Documentation-like solution:

jQuery("#clickable_element").click(function(){
    jQuery('#main_content_container').infinitescroll('retrieve');
        return false;
});

Note:
You may have to add the manual trigger behavior if you are working with masonry or isotope in order to make it work. Just include manual-trigger.js after infinitescroll and pass the behavior by passing behavior: 'twitter' when calling the plugin.

Answer 2

I made the following tweak to ensure the navigation link showed up after being clicked the first time:

jQuery("#clickable_element").click(function(){
    jQuery('#main_content_container').infinitescroll('retrieve');
    jQuery('#pagination').show();
    return false;
});

Hi Divot, is there a way of hiding the button when there are no more posts? If I do what you have suggested, the button will show all the time even with no more posts. – Felipafelipe

Answer 3

Maybe... $('#next a').click(); ?

No I wish it was that simple, everything else in my script only loads with jQuery(document).ready(function(){ } function. And the infinite scroll does work (which proves jQuery instead of $) just not the manual trigger. – Statuesque

seems this should work... jQuery('ul#infinite').infinitescroll('retrieve') – Bedder

If that's the case, perhaps editing your original answer as .click() does NOT work. and a Maybe... answer is unhelpful. I prefer not to down vote or edit myself, so please edit. – Adams
