jQuery.extend({

        var params={url:url,data:null,callback:null,sender:null};
        for(var i=1;i<arguments.length;i++){
            if(arguments[i]!=null){
                var ptype=typeof(arguments[i]);
                if(ptype=="function"){

                        return null;
                }
                else if(ptype=="object"){
