JQuery Confirm 1.7 breaks $ .getJSON () in jQuery 1.5?

Good afternoon!

I run the plugin on jQuery 1.4.4 s getJSON(), after upgrading to 1.5, callback is not called. The returned JSON is valid (I checked with a validator).

I also noticed an extra get parameter ?callback=...that jQuery adds to the URL

I seem to understand how to create a test case, and it seems that the reason is JQuery validate 1.7 (latest version):

<script type="text/javascript">
$(function(){
    $.ajaxSetup({ cache: false });
    $('#clickme').click(function(){
        var params = {userid : 'some-user-id-to-choose-right-temp-FTP-folder-for-the-user'};
        $.getJSON('/ajax-page_material-edit-ftp-filelist.php', params, function(data) {
            console.log(data);
        });
    });
});
</script>

<a href="#" id="clickme">Click Me!</a>

</body>
</html>

Perhaps this code in the plugin is the reason:

// ajax mode: abort
// usage: $.ajax({ mode: "abort"[, port: "uniqueport"]});
// if mode:"abort" is used, the previous request on that port (port can be undefined) is aborted via XMLHttpRequest.abort() 
;(function($) {
    var ajax = $.ajax;
    var pendingRequests = {};
    $.ajax = function(settings) {
        // create settings for compatibility with ajaxSetup
        settings = $.extend(settings, $.extend({}, $.ajaxSettings, settings));
        var port = settings.port;
        if (settings.mode == "abort") {
            if ( pendingRequests[port] ) {
                pendingRequests[port].abort();
            }
            return (pendingRequests[port] = ajax.apply(this, arguments));
        }
        return ajax.apply(this, arguments);
    };
})(jQuery);
