Globally configure all $.ajax requests to support retry on timeout

Question

I need a way to set some kind of timeout function globally with $.ajaxSetup that will allow my Phonegap application to keep retrying an ajax GET or POST every time there is a timeout due to a bad internet connection.

I use Backbone.js so most jquery plugins won't work for this, I would some help writing one global piece of code which will handle retries.

Thank you.

You can use jQuery.ajaxSetup(options).

Set default values for future Ajax requests. Its use is not recommended.

Example

$.ajaxSetup({
  timeout: TimeoutValue
});

Apart from that if you want perform call again on timeout, I will suggest you to create wrapper for ajax call like.

function myAjax(options){
    var myOptions = {
        timeout: TimeoutValue,
        error: function( jqXHR, textStatus, errorThrown) {
            //textStatus can one of these "timeout", "error", "abort", and "parsererror"
            if(textStatus === "timeout") {
                //Recall method once again
                myAjax(options)
            }
        }           
    };

    options = $.extend(true, myOptions , options);
    $.ajax(options)
}

And Use the function just like $.ajax

Hi Satpal, this is a good answer, but I need a global function that will handle ALL my application calls, this is why I wanted some kind of function done using $.ajaxSetup only. — Ilya Karnaukhov, Aug 27 '14 at 10:23

Found a solution to make all AJAX calls work with a retry timeout.

$(document).ajaxError(function (e, xhr, options) {
    if(xhr.status == 0){
        setTimeout(function(){
            console.log('timeout, retry');
            $.ajax(options);
        }, 5000);
    }
});
