Call jqXHR.abort without triggering an error?

Question

I have a jqXHR object which I get from a backbone collection:

var xhr = this.collection.fetch({
  error: function() { alert("oh noes!"); }
});

Sometimes I then need to call xhr.abort(). But this is also triggering the error callback.

How can I call xhr.abort() without triggering an error?

The error function will always be called. But you can check if it was an abort in the error function and ignore it:

    var xhr = this.collection.fetch({
        error: function(model, jqXHR, options) {
               if (jqXHR.textStatus != "abort")
                  alert("oh no!");
        }
    });
