            }
            return $data;
        }
        return view('posts');
    }
}

Step 6 – Create a blade view

<!doctype html>
<html lang="en">
  <head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
  <meta name="csrf-token" content="{{ csrf_token() }}">
  <title>Laravel 8 load more page scroll - Tutsmake.com</title>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" />
  
  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<style>
   .wrapper > ul#results li {
     margin-bottom: 2px;
     background: #e2e2e2;
     padding: 20px;
     width: 97%;
     list-style: none;
   }
   .ajax-loading{
     text-align: center;
   }
</style>
</head>
 
<body>
 
  <div class="container">
   <div class="wrapper">
    <ul id="results"><!-- results appear here --></ul>
     <div class="ajax-loading"><img src="{{ asset('images/loading.gif') }}" /></div>
   </div>
  </div>
</body>
</html>

This blade view file displays your all blog posts when you scroll the page down.

<script>
   var SITEURL = "{{ url('/') }}";
   var page = 1; //track user scroll as page number, right now page number is 1
   load_more(page); //initial content load
   $(window).scroll(function() { //detect page scroll
      if($(window).scrollTop() + $(window).height() >= $(document).height()) { //if user scrolled from top to bottom of the page
      page++; //page number increment
      load_more(page); //load content   
      }
    });     
    function load_more(page){
        $.ajax({
           url: SITEURL + "posts?page=" + page,
           type: "get",
           datatype: "html",
           beforeSend: function()
           {
              $('.ajax-loading').show();
            }
        })
        .done(function(data)
        {
            if(data.length == 0){
            console.log(data.length);
            //notify user if nothing to load
            $('.ajax-loading').html("No more records!");
            return;
          }
          $('.ajax-loading').hide(); //hide loading animation once data is received
          $("#results").append(data); //append data into #results element          
           console.log('data.length');
       })
       .fail(function(jqXHR, ajaxOptions, thrownError)
       {
          alert('No response from server');
       });
    }
