jquery调用一般处理程序的多个方法

jquery调取方式：
<script type="text/javascript">
                            $(function () {
                                $.get("/Ashx/GetTraceabilityJson.ashx?" + new Date(), { ‘ProductCode‘: ‘<%=ProductCode %>‘, ‘BatchNumber‘: ‘<%=BatchNumber %>‘, ‘command‘: ‘GetFlowGraph‘ }, function (data) {
                                    if (data != null) {
                                        var data = $.parseJSON(decodeURIComponent(data));
                                        var nodes = eval(data[0].value);
                                        var links = eval(data[1].value);

                                        if (nodes.length > 0) {

                                            setLinks(links);
