I have this code, and when the stop button is clicked, I need to stop the ajax, but for some reason ajax is not aborting.

var started = false;
  $(document).ready(function () {
  $('#start').click(function () {
  var count = $("#names").val();
  var line = count.split("\n");
  started = true;
  line.forEach(function(value, index) {
      setTimeout(
              var ajaxCall = $.ajax({
                  url: url,
                  type: 'GET',
                  data: someData,
                  success: function(result) {
                      //some works here
                   }
              });
                      $('#stop').click(function () {
                      ajaxCall.abort();   //abort Ajax
                      $('#check').attr('disabled', false);
                      $('#stop').attr('disabled', 'disabled');

                  })
          }, 2000 * index);
       });
  });

});
