Question

The use case would be if the response it gets isn’t what it wanted it can call itself again.

$.post(qrLoginAjax.ajaxurl, { 
    userID : '11234324'
},function( response ) {
    if (response.userID != 'undefined'){
        //do stuff
    } else {
        // call $.post again
    }
});

How would I do that?

Thanks

You could do something like this:

var sendAjax = function() {
    $.post('/foo', function(result) {
        if (response.userID != 'undefined') {
            // do stuff
        } else {
            // resend the AJAX request by calling the sendAjax function again
            sendAjax();
        }
    });
};

sendAjax();

But sending AJAX requests like this seems like a bad design decision in my opinion. You should ensure that you don’t get into an infinite recursion by using for example a number of retries counter.
