function SelectProject() {



var a = new Array;

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

if (typeof (r) != 'undefined') {

var arr = r.split(";");

$("#hidProjectInnerID").val(arr[0]);

$("#txtProjectNo").val(arr[1]);

$.getJSON("../Handler/GetProjectInfor.ashx", { key: "PaymentStatement", InnerID: $("#hidProjectInnerID").val() },

function (json) {

$("#labFinalCustomer").text(json.finalclient);

$("#labOrderNo").text(json.orderno);

var strDeviceTr = "";

$.each(json.workinghours, function (i, item) {

strDeviceTr += "<tr><td><lable name="infor"> " + item.description + "</lable> </td>";

strDeviceTr += "<td> </td>";

strDeviceTr += " <td><lable name="infor"> " + item.hoursdays + "</lable></td>";
