前台:

function SelectProject() {
var a = new Array;
var r = window.showModalDialog('SelProject.aspx', a, "dialogWidth=1000px; dialogHeight=600px; resizable: yes");

$("#hidProjectInnerID").val(arr[0]);
$("#txtProjectNo").val(arr[1]);
$.getJSON("../Handler/GetProjectInfor.ashx", { key: "PaymentStatement", InnerID: $("#hidProjectInnerID").val() },
function (json) {
$("#labFinalCustomer").text(json.finalclient);

var strDeviceTr = "";
$.each(json.workinghours, function (i, item) {
strDeviceTr += " " + item.description + "";
