[jQuery] ajaxcfc - if ajax call fails - how does it get handled?

[Duncan]

I have a page that submits checkboxes as they are checked on the way
down a form.

The click hides the checkbox for a loading gif, submits the ID via
ajax, and on its return changes the loading icon to a tick image.

What I want to know is how to handle a failure of the ajax request.

currently I have the following:

$.AjaxCFC({
                  url: "/packages/ajax/primaryInvitee.cfc",
                  method: "addInvitee",
                  data: options,
                  success: function(r) {
                        thisCheck = "check_" + r.LOGINID;
                        thisLoad = "load_" + r.LOGINID;
                        if(r.RESULT > 0){
                                
$('#'+thisLoad).attr("src","/pics/icon_tick_grey.gif");
                        }else{
                                $('#'+thisCheck).css("display","");
                                $('#'+thisLoad).css("display","none");
                        }
                        //sDumper(r);
                  }

I cant find a failure equivalent to "success:".

What about a timeout? How would I handle this?

Thanks in advance!
