Ajax calls and JQuery: stop previuos ajax calls -

in jsp page, when user clicks button, ajax call triggered. if user clicks again , again button, last ajax call valid , response considered.

i use:

  var lastrequest=null;   $('#button').click(function() {              if (lastrequest) {     lastrequest.abort();     lastrequest = null;   }    lastrequest = $.ajax({         type: "post",         url: "myaction.do",             success: function (response) {                   response= $('<div/>').append(response);               }       });          }); 

with firebug, see request aborted, not all. think if ajax call triggered, it's not possible ignore response, it?

edit

if set var in myaction.do , read in success callback, possible have conflict in success callback?

in case, how prevent behaviour?

my experience aborting ajax-calls can pretty random when works.

a workaround i've used once or twice counters:

var lastrequest=null; var started = 0, finished = 0; $('#button').click(function() {               ++started;   lastrequest = $.ajax({         type: "post",         url: "myaction.do",             success: function (response) {                   //only stuff on last active request                   if(++finished == started)                     response= $('<div/>').append(response);               }       });        });
