Jquery-ajax control data post -

-

i not understand why when use .post() function data posted more 1 time how can control , stop think? in advance.

best regards that's code:

case "mod" :             $.post("./php/"+eti[indice]+".php",                 {azione: "carica", contratto:contratto},                 function(xml)                 {                     if ($("status", xml).text()=="1")                     {                         scorridati(xml);                         $.post("./php/"+eti[indice]+".php",                         {azione: "vedi", contratto: contratto },                         function(xml)                         {                             if ($("status", xml).text()=="1")                             {                                 var lun=$("#"+eti[indice]+"_"+indice).length;                                 if (lun == 0)                                 {                                     $("#scheda_sch").append("<div style='clear:both'><div style='float:right' id='mod_def'><div id='"+eti[indice]+"_"+indice+"' class='bt'>modifica</div></div></div>");                                     scorridati(xml);                                 }                             }                             else                             {                                 $("#scheda_ris").html("<p><img src='./img/validyes.png' alt='ok'> attenzione!<br>codice non trovato!</p>");                             }                         },'xml');                     }                     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");                         });                     }                 },'xml'             );         break;

the problem generated when click on modifica, more 1 button , data posted several times..

ciao h

generally kind of things happens when end users having habit double click buttons uses app. may cause post request twice if not disabling button after first click

i hope if add code appropriately handle thing , resolve problem. can following things solution:

  • disable control causes post event on first occurrence
  • you can bind click , double click both events same function , use global variable stores count of click, if count > 1 don't click it. in result of post can make count 0 again.

hope help
