Select din Mysql si display cu Ajax fara refresh

[Alex Dumitru]

Codul de mai jos il pui pe pagina de comentarii. Comentariile in sine le bagi in div-ul cu id ReloadThis

    <script type="text/javascript">

      function Ajax()
      {
        var
          $http,
          $self = arguments.callee;

        if (window.XMLHttpRequest) {
          $http = new XMLHttpRequest();
        } else if (window.ActiveXObject) {
          try {
            $http = new ActiveXObject('Msxml2.XMLHTTP');
          } catch(e) {
            $http = new ActiveXObject('Microsoft.XMLHTTP');
          }
        }

        if ($http) {
          $http.onreadystatechange = function()
          {
            if (/4|^complete$/.test($http.readyState)) {
              document.getElementById('ReloadThis').innerHTML = $http.responseText;
              setTimeout(function(){$self();}, 10000);
            }
          };
          $http.open('GET', 'random.php' + '?' + new Date().getTime(), true);
          $http.send(null);
        }

      }

    </script>
    
    <script type="text/javascript">
      setTimeout(function() {Ajax();}, 10000);
    </script>
    <div id="ReloadThis"><?php /* Aici pui comentariile */ ?></div>

Apoi faci o pagina random.php cu codul asta in ea:

<?php
echo rand();
?>

Codul l-am gasit aici si l-am testat, merge.
