How to detect if a request was aborted?

Question

I am making a request and then right after it I abort.

var x = $.get(url, function (d, e, xhr) { alert(d); });
x.abort();

The problem is that it executes the success function and returns empty data... (example here)

Is there a jQuery method to abort? or Is there a way to check if the xhr was aborted?

Answer 1

The best way to detect request abortion and avoiding false positive from offline mode :

$("#loading").ajaxError(function(event, xhr) {
  if (xhr.status === 0) {
    if (xhr.statusText === 'abort') {
      // Has been aborted
    } else {
      // Offline mode
    }
  }
});

Answer 2

I found here that the xhr will return with status 0. Seems to be a jQuery 1.4+ bug. On 1.3 it called the error handler.
