  if $('#infinite-scrolling').size() > 0
    $(window).on 'scroll', ->
      more_posts_url = $('.pagination .next_page a').attr('href')
        if more_posts_url && $(window).scrollTop() > $(document).height() - $(window).height() - 60
            $('.pagination').html('<p> loading <p>')
            $.getScript more_posts_url
        return
      return

Answer 1

more_posts_url 变量后面有一个额外的缩进 block :

if $('#infinite-scrolling').size() > 0
  $(window).on 'scroll', ->
    more_posts_url = $('.pagination .next_page a').attr('href')
    if more_posts_url && $(window).scrollTop() > $(document).height() - $(window).height() - 60
      $('.pagination').html('<p> loading <p>')
      $.getScript more_posts_url
    return
  return
