前台页面：组装json字符串

function passengersSelect() {

        var passengerList = new Object(); ////解析JArray字符串则new Array();

        $("#tbodyPass tr").each(function (trIndex) {

            var passenger = new Object();

            var tr = $(this);

            //旅客ID

            passenger["PsngrId"] = tr[trIndex].id.substring(3);

            tr.find("td").each(function (tdIndex, td) {

                //证件类型

                if (tdIndex == 4) {

                    passenger["CardType"] = $(td).find("option:selected").val();//选中的值

                }

                //证件号码

                if (tdIndex == 5) {

                    passenger["CardNum"] = td.innerText;

                }

            });

            passengerList[trIndex] = passenger;

        });

        //赋值给隐藏域

        //先清除

        $("#BookingTicket_PassengerList_HiddenField").val("");

        $("#BookingTicket_PassengerList_HiddenField").val(JSON.stringify(passengerList));
