Question

I am trying to create a commenting system whereby admins are able to moderate comments and users are able to post comments all in the one page load. I have all the backend knowledge on how to delete the comments, but I really have to know how the new comments could be loaded from the database and shown on the current page.

Edit: More specifically what would the actual javascript look like that would render the new replies?

Answer 1

You’ll want a periodic AJAX call to poll the server for new comments.

You should have a datetime of the latest answer the browser knows and the question ID to query the server, to optimize your traffic.

Using JQuery:

var refreshId = setInterval(function() {      $.getJSON('http://server.com/form?question=' + questionId + '?time=' + datetimeStamp',         function(data){           $.each(data.items, function(i,item){             $('#comments').append( // new div with content)           });         });  }, 3000);
