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 + =" "+ Item. description +" ";
StrDeviceTr + =" ";
StrDeviceTr + =" "+ Item. hoursdays +" ";
StrDeviceTr + ="0.8";
StrDeviceTr + =" "+ Item. workinghour +" ";
StrDeviceTr + ="0.8";
StrDeviceTr + =" "+ Item. workinghour +" ";
StrDeviceTr + =" ";
StrDeviceTr + ="";
});
$ ("# Infor"). append (strDeviceTr );
});
}
}
