Infinite scroll using popup callback

Question

I use Infinite scroll and Magnific Popup.

The popup works with content that is "page 1", but after that it does not work. I tried using the callback for MagnificPopup in the infinScroll call.

$grid.infiniteScroll({
path: '.pagination__next',
append: '.grid__item',
outlayer: msnry,
status: '.page-load-status',
}, function( newElements ) {
  $('.open-pop').magnificPopup({
  type: 'inline',
  mainClass: 'mfp-fade',
  fixedContentPos: false,
   gallery: {
   enabled: true,
   navigateByImgClick: false,
   }
 });

 });

My question is similar to this Massive popup and endless scroll that I tried unsuccessfully to implement.

Potentially an additional complication, I use Freemasonry. This is my complete code:

// init Masonry

var $grid = $('.grid').masonry({
 itemSelector: 'none', // select none at first
 columnWidth: '.grid__col-sizer',
 gutter: 26,
 percentPosition: true,
 stagger: 30,
 // nicer reveal transition
 visibleStyle: { transform: 'translateY(0)', opacity: 1 },
 hiddenStyle: { transform: 'translateY(100px)', opacity: 0 },
});

// get Masonry instance
var msnry = $grid.data('masonry');

// initial items reveal
$grid.imagesLoaded( function() {
$grid.removeClass('are-images-unloaded');
$grid.masonry( 'option', { itemSelector: '.grid__item' });
var $items = $grid.find('.grid__item');
$grid.masonry( 'appended', $items );
});

$grid.infiniteScroll({
path: '.pagination__next',
append: '.grid__item',
outlayer: msnry,
status: '.page-load-status',
}, function( newElements ) {
 $('.open-pop').magnificPopup({
 type: 'inline',
 mainClass: 'mfp-fade',
 fixedContentPos: false,
 gallery: {
  enabled: true,
  navigateByImgClick: false,
 }
});

});

Answer 1

Use the onInitevent for the callback function.

onInit: function() { this.on( 'append', function() {...}) }
