Jquery datatables在fnReloadAjax上保留现有fnServerParams

我试图修改fnReloadAjax，以将我之前设置的现有aoData保留在中

  fnServerParams:function(aoData) {
     var serializedForm = $('form#searchform').serializeArray();
     for (var n in serializedForm) {
        var tmpobj = serializedForm[n];
        var key = tmpobj['name'];
        var value = tmpobj['value'];
        aoData.push({"name":key,"value":value});
     }
}

它们被重新设置为

$.fn.dataTableExt.oApi.fnReloadAjax = function ( oSettings, sNewSource, fnCallback,bStandingRedraw )
...
...
...
var aData = []; # reset here

---

如何获取现有的aData参数，而不是将其重置为空数组？

fnReloadAjax不适用于bServerSide=true
