title: Scrolling top of the Popup window with jQuery
body: <p>I have popup window and there is a  in it with the id of PopupDiv and I want to scroll top after returning the Ajax request made to the Controller (when there is an error, I return message with Json and I display it on the popup window). I have found many different ways on web and tried the methods below, but none of them is not working (they works a whole page instead of popup window). Any idea?</p>
  
  <p><strong>View:</strong></p>
  
  <pre><code>&lt;div id="PopupDiv" style="height: 421px; overflow-y: scroll; margin-top: -7px; margin-bottom:-14px "&gt;
  
  &lt;script&gt;
  $.ajax({
          type: "POST",
          url: '@Url.Action("Create", "Issue")',
          data: formdata,
          dataType: "json",
          processData: false,
          contentType: false, 
          success: function (response) {
          if (!response.success) {
  
          //I tried the following by one by one, but none of them is working:
          messageThread.scrollTop = messageThread.scrollHeight;
          $('html, form').animate({ scrollTop: $('#PopupDiv').position().top }, 'slow');          
          $(window).scrollTop(300);
          $("html, body").animate({ scrollTop: "1024px" }, 5000);
          var objDiv = document.getElementById("#PopupDiv");
          objDiv.scrollTop = objDiv.scrollHeight;
          }
      }
  });
  &lt;/script&gt;
  </code></pre>
