var version="VERSION";
var topicAlertId="ID";
jQuery.ajax({
        url: "/t"+topicAlertId+"-?view=newest",
        success: function(result) {
            var html = jQuery(result);
 
         
            if (version=="phpbb3") {
              var alertBody= html.find("div.post .content .codebox code").eq(-1).text();
              var id = html.find("div.post").eq(-1).attr("id");
            }
         
            if (version=="phpbb2") {
              var alertBody= html.find("tr.post .postbody .codebox .cont_code").eq(-1).text();
              var id = html.find("tr.post").eq(-1).attr("id");
            }
         
            if (version=="punbb") {
              var alertBody= html.find("div.post .postbody .entry-content .codebox .cont_code code").eq(-1).text();
              var id = html.find("div.post .postmain .posthead").eq(-1).attr("id");
            }
         
            if (version=="invision") {
              var alertBody= html.find("div.post .post-entry .codebox.contcode dd code").eq(-1).text();
              var id = html.find("div.post").eq(-1).attr("id");
            }
         
            if(localStorage.getItem(id)!='read' && sessionStorage.getItem(id)!=location.pathname) {
                  $('body').append(alertBody);
                  $('.realTime_alert .close').click(function() {
                    $(this).closest('.realTime_alert').fadeOut();
                    localStorage.setItem(id,"read");
                  });
            }
          if(sessionStorage.getItem(id)!=location.pathname) {
              sessionStorage.setItem(id, location.pathname);
          } else {
              sessionStorage.setItem(id, location.pathname);
          }
        },
});
return topicAlertId;
}
 
$(function(){
if($("#logout").length) {
  realTime_alert();
  setInterval('realTime_alert();', 30000); // Reactualisation toutes les 30s
}
});

• var topicAlertId = "ID"; devi sostituire ID con l'ID dell'oggetto creato (esempio: 232)
  
• var version = "VERSION"; devi sostituire VERSION con la versione del tuo forum (phpbb2, phpbb3, punbb o invision).
  
• Se desideri rendere questi avvisi visibili agli ospiti, devi sostituire:
  

  Codice:

  $(function(){
if($("#logout").length) {
  realTime_alert();
  setInterval('realTime_alert();', 30000); // Reactualisation toutes les 30s
}
});

  
  con:
  

  Codice:

  $(function(){
  realTime_alert();
  setInterval('realTime_alert();', 30000); // Reactualisation toutes les 30s
});
