Stop all active ajax requests in jQuery

Question

I have a problem, when submitting a form all active ajax request fail, and that triggers error event.

How to stop all active ajax requests in jQuery without trigerri

Answer 1

Using ajaxSetup is not correct, as is noted on its doc page. It only sets up defaults, and if some requests override them there will be a mess.

I am way late to the party, but just for future reference if someone is looking for a solution to the same problem, here is my go at it, inspired by and largely identical to the previous answers, but more complete

// Automatically cancel unfinished ajax requests 
// when the user navigates elsewhere.
(function($) {
  var xhrPool = [];
  $(document).ajaxSend(function(e, jqXHR, options){
    xhrPool.push(jqXHR);
  });
  $(document).ajaxComplete(function(e, jqXHR, options) {
    xhrPool = $.grep(xhrPool, function(x){return x!=jqXHR});
  });
  var abort = function() {
    $.each(xhrPool, function(idx, jqXHR) {
      jqXHR.abort();
    });
  };

  var oldbeforeunload = window.onbeforeunload;
  window.onbeforeunload = function() {
    var r = oldbeforeunload ? oldbeforeunload() : undefined;
    if (r == undefined) {
      // only cancel requests if there is no prompt to stay on the page
      // if there is a prompt, it will likely give the requests enough time to finish
      abort();
    }
    return r;
  }
})(jQuery);
