jqgrid里边的触发器只能触发一次，有没有办法能够解决

//修改

        function update(rowid) {

            if (rowid != null) {

                var rowObject = $("#myTab").jqGrid('getRowData', rowid);

                var term = rowObject.termYear;

                var yeardate = textList(term, "YEAR");

                var quarterdate = textList(term, "QUARTER");

                var monthdate = textList(term, "MONTH");

                $("#myTab").setColProp("termYear", { editoptions: { value: yeardate} });

                $("#myTab").setColProp("termQuarter", { editoptions: { value: quarterdate} });

                $("#myTab").setColProp("termMonth", { editoptions: { value: monthdate} });



                $("#myTab").jqGrid('editRow', rowid, true);

                $("#myTab").setColProp(

                        "op",

                        {

                            formatter: function updFormatter() {

                                return '<a href="#" onclick=javascript:upd("' + rowid + '") >保存</a> '

                                      + '<a href="#" onclick=javascript:cancel()>取消</a>';
