Jquery Ajax error handling to ignore aborted

Error comes from when the web page refresh too much fast than it can load.

For example, a web page load a huge data, even with ajax pagination, and users refresh multiple times of this page

 

Solution which resolved this problem :

var unloaded = false;
$(window).bind('beforeunload', function(){
    unloaded = true;
});

$(document).ajaxError(function(event, request, settings) {
    if (unloaded || request.statusText == "abort") {
        return;
    }
    ...
}
