Question

I remember having this problem once before but I dont’ know which project it was on or how I fixed it.

I have an ajax ‘add to favorite’ button, and I also have infinite scroll which ajax loads pages when you reach the bottom of the page. The problem is the ajax doesn’t apply to the newly appended content:

// Favorites
  $('.res-list .star').click(function(){
    var starLink = $(this);
    var listItem = $(this).parent().parent();
    
    if ($(starLink).hasClass('starred')) {
       $(starLink).removeClass('starred');
     } else {
       $(starLink).addClass('starred');
     }
     $.ajax({
       url: '/favorites/?id=' + $(starLink).attr('data-id'),
       type: 'PUT',
       success: function() {
         
         if ($(starLink).hasClass('starred')) {
           $(listItem).animate({
             backgroundColor: '#FFF8E4'
           }, 400);
         } else {
           $(listItem).animate({
             backgroundColor: '#ffffff'
           }, 400);
         }
       }
     });
     return false;
  });

Answer 1

You need live event

$('.res-list').on('click', '.star', function() {

   // code here
});

or use delegate()

$('.res-list').delegate('.star', 'click', function() {

       // code here
    });

read about delegate()
