jQuery Grid Plugin - jqGrid

I managed to handle this issue by modifying the jqGrid source code, as displayed below, to remove any functions exported with the grid.  I will look at submitting this change to the github later, when I have some time to sit down and understand that process.

        jqGridExport : function(o) {
            o = $.extend({
                exptype : "xmlstring",
                root: "grid",
                ident: "\t"
            }, o || {});
            var ret = null;
            this.each(function () {
                if(!this.grid) { return;}
                var gprm = $.extend({},$(this).jqGrid("getGridParam"));
                // we need to check for:
                // 1.multiselect, 2.subgrid  3. treegrid and remove the unneded columns from colNames
                if(gprm.rownumbers) {
                    gprm.colNames.splice(0,1);
                    gprm.colModel.splice(0,1);
                }
                if(gprm.multiselect) {
                    gprm.colNames.splice(0,1);
                    gprm.colModel.splice(0,1);
                }
                if(gprm.subGrid) {
                    gprm.colNames.splice(0,1);
                    gprm.colModel.splice(0,1);
                }

                /* BEGIN: Added by Mike Manard, 1/31/2012, to prevent export of invalid JSON */
                for (var param in gprm) {
                    if (typeof (gprm[param]) === 'function') {
                        delete gprm[param];
                    }
                }
                /* END: Added by Mike Manard, 1/31/2012 */

                gprm.knv = null;
                if(gprm.treeGrid) {
                    for (var key in gprm.treeReader) {
                        if(gprm.treeReader.hasOwnProperty(key)) {
                            gprm.colNames.splice(gprm.colNames.length-1);
                            gprm.colModel.splice(gprm.colModel.length-1);
                        }
                    }
                }
                switch (o.exptype) {
                    case 'xmlstring' :
                        ret = "<"+o.root+">"+xmlJsonClass.json2xml(gprm,o.ident)+"</"+o.root+">";
                        break;
                    case 'jsonstring' :
                        ret = "{"+ xmlJsonClass.toJson(gprm,o.root,o.ident,false)+"}";
                        if(gprm.postData.filters !== undefined) {
                            ret=ret.replace(/filters":"/,'filters":');
                            ret=ret.replace(/}]}"/,'}]}');
                        }
                        break;
                }
            });
            return ret;
        },
