Question

I have many jquery ajax requests, sent with one function.

function sendData(data){
    $.post("somepage", {"data": data}, function() {}, "json")
    .fail(function(jqXHR, textStatus, errorThrown){
        sendData(***previuoslySentData***);
    });
}
sendData(1);
sendData(2);
sendData(3);
...

as you can see, when a request fails I want to be able to send the request again with previously sent data.
how can I get back sent data on xhr error?
I thought it should be in xhr but I couldn’t find anything.
I’m also interested in any other solution for this problem.

The way you’ve wrapped your AJAX request in a function of its own, you’re effectively creating a new closure, which means that the data variable that you accept as an input parameter, will be still be usable in your .fail callback.
