    copied!<p>I have used a code that I got from a site for infinite scrolling using knockout js, with some changes in it.</p> <p>Here's my html and javascript code:</p> <pre><code>&lt;div id="main" data-bind="foreach: items, event: { scroll: scrolled }"&gt; &lt;div data-bind="text: name"&gt;&lt;/div&gt; &lt;/div&gt; &lt;script type="text/javascript"&gt; var viewModel = { items: ko.observableArray([]), scrolled: function(data, event) { var elem = event.target; if (elem.scrollTop &gt; (elem.scrollHeight - elem.offsetHeight - 200)) { getItems(6); } }, maxId: 0, pendingRequest: ko.observable(false) }; function getItems(cnt) { if (!viewModel.pendingRequest()) { var entries = []; for (var i = 0; i &lt; cnt; i++) { var id = viewModel.maxId++; entries.push({ id: id }); } viewModel.pendingRequest(true); $.ajax({ type: 'POST', url: 'echojson.php', data: { json: ko.toJSON(entries), delay: .1, id:id, cnt:cnt }, success: function(entries) { ko.utils.arrayForEach(entries, function(entry) { alert(entry); viewModel.items.push(entry); }); viewModel.pendingRequest(false); }, error: function() { viewModel.pendingRequest(false); }, dataType: 'json' }); } } ko.applyBindings(viewModel); getItems(6); &lt;/script&gt; </code></pre> <p>And here is the php file code from where I am getting the data:</p> <pre><code>&lt;?php include 'dbconfig.php'; $jsonarr=json_decode($_POST['json'],true); $cnt=$_POST['cnt']; if(isset($_POST['id'])){ $offset=$_POST['id']; } if($offset&lt;=$cnt){ $offset=0; } else{ $offset=$offset-($cnt-1); } $json=array(); $sql="SELECT * FROM user LIMIT $offset,".$cnt; $exec=mysqli_query($con,$sql); while($row=mysqli_fetch_array($exec)){ $name=strtoupper($row['fname'].' '.$row['lname']); $profilepic=$row['profilepic']; $city=$row['city']; $json[]=$name.' '.$profilepic.' '.$city; } echo json_encode($json); ?&gt; </code></pre> <p>On scroll, I get the correct number of div added but the data in <code>items</code> array is not displayed in the div with id <code>main</code>. </p> <p>When I alert elements in array items, I do get the values in it. But this updated array is not getting binded to the div it seems.</p> <p>Please help me fix this.</p>
