Good day!

I’ve running plugin on jQuery 1.4.4 with getJSON(), after uprade to 1.5 callback is not called. The returned JSON is valid (I’ve checked with validator).

Before digging more I’d like to as if this a common problem? Also I noticed additional get parameter ?callback=... which jQuery adds to the URL

Thanks in advance!

Edit: It seems I figured out how to create a test case and it seems that JQuery validate 1.7 (latest version) is the cause:

$(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>

Maybe this code in plugin is the cause:

// 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);
