jquery/ajax/php big problem -

-

i've big problem creating intranet. made main page label menu, clicking on voices load form structure page in div , populate ajax, works problem starts when try add new data or update data, posted information sent several times php process page. sent 1 time other time 3-4 or more times, seems data cached in strange way... experience may problem? ajax code written in main page , load page may problem? better save in separated page?

thanks in advance , excuse me generic question..

ciao h.

that's piece of inserting code:

$("#new_def").live("click", function() {     var stringa = $("#new_def > div").attr("id");     var nodi=stringa.split("_");     $("#scheda_ris").html("");     $.post("./php/"+nodi[0]+".php",         {azione: "new_def", dati: $("form").serialize()},         function(xml)         {              if ($("status", xml).text()=="1")             {                 $("#scheda_ris").append("<img src='./img/validyes.png' alt='ok'><span style='color:green'>" +$("msg", xml).text()+ "</span>\n");                 $("#scheda_sch").html("");                 postadati("new", $("contratto", xml).text(), nodi[1]);             }             else             {                 $(xml).find("errore").each(function()                 {                     $("#scheda_ris").append("<img src='./img/validno.png' alt='errore'><span style='color:red'>"+$(this).text()+"<br></span>\n");                 });             }         }     ); });
