jquery - ajax call not reset old data -

i using ajax in website, working fine not success data on next call, mean if on first call, data 1 , 0 , on second call data 0 , 1, showing on 2nd call 1, 0, 0, 1

function checkform(){ var userid = $("#userid").val(); var email = $("#email").val(); $.ajax({     url:path+"ajax_getpass.php",     data:{userid : userid, email : email},     cache:'false',     type:'post',     datatype:"json",     success: function(data_send){         $(document).ajaxcomplete(function(event, request) {             //data = $.parsejson(data);             alert(data_send.email);             alert(data_send.userid);         });     } }); return false; } 

please tell me wrong.

this because add more , more functions ajaxcomplete() every time ajax request successful. when success code called first time, 1 function called ajaxcomplete(). next request, function added, 2 functions called.

use code instead:

$.ajax({     url:path+"ajax_getpass.php",     data:{userid : userid, email : email},     cache:'false',     type:'post',     datatype:"json",     success: function(data_send){         alert(data_send.email);         alert(data_send.userid);     } }); 

you need $.ajaxcomplete() when want respond ajax requests sent other part of code (i.e. in places can't specify success function).

think of kind of global "success" function.
