SOLVED
can I return a string in a customized dialog box created with app.execDialog()?
Adobe LiveCycle Designer Cookbooks by BR001: Using app.execDialog() in an Adobe Designer Form
I'm following the above post and trying to do the following:
I want to write the output from one of the list box selection from the dialog box back to PDF, what shall I script?
Something like document.write() in Javascript (see: http://www.tutorialspoint.com/javascript/javascript_dialog_boxes.htm ). I've tried to use document.write() in dialog box script, but it doesn't seem to work.
Or can the dialog box return a string value?
According to the PDF sample in the first link, This dialogObject is what's returned when you see a dialog box:
var dialogObject = {
LST1: ({}),
execDialog: function() {
return app.execDialog(dialogDescriptor);
},
selectedItem: function(control) {
if (typeof(control) === "string") {
control = this[control];
}
for (var item in control) {
if (typeof(control[item]) === "object") {
var r = this.selectedItem(control[item]);
if (r !== undefined) {
return r;
}
} else {
if (control[item] > 0) {
return control[item];
}
}
}
},
};
return dialogObject;

Apart from initialize function, I also need to pass the value into:
var dialogObject =
{
LST1: [some value]
}
So now it works, thank you!
Some more questions about dialog box:
I used to be a Java based developer, so some features of javascript are new to me. Please excuse me if I'm asking simple common sense questions, and perhaps give me some hint or reference so that I can do some more research accordingly. Big thanks!

From the sample PDF:
var list = { "Aland Islands":-248,
"Albania":-8,
"Algeria":-12,}
I'm curious why the map is defined in this way (and even though the value is a negative yet output is a positive!). There's a problem caused: the list is now displayed in alphabetical order. Yet I want to display the list in numeric order.
So I make the list in variable "Data" as:
list=
{248:"Aland Islands",
8:"Albania",
12:"Algeria"
}
In the code that generate the dialog box, please see my comment underlined:
var a = dialog();
a.LST1 = Data.list;
function dialog() {
var dialogDescriptor = {
...
"LST1": function(dialog) {
var lst1 = dialog.store()["LST1"];
for (var item in lst1) {
if (lst1[item] > 0) {
var selectedValue = item;
break;
}
}
app.alert("You selected " + selectedValue + " code " + dialogObject.selectedItem(lst1)); // output: 248 and 1
}
...
}
var dialogObject = {
selectedItem: function(control) {
if (typeof(control) === "string") {
control = this[control];
}
for (var item in control) {
if (typeof(control[item]) === "object") {
var r = this.selectedItem(control[item]);
if (r !== undefined) {
return r;
}
} else {
if (control[item] > 0) {
return control[item]; // when I select the first item of "list", item=248, control[item]=1. What does control[item] mean? // I was expecting it to be the string "Aland Islands".
}
}
}
}
}
}
What's more, the list now display:
I cannot find the code to change and display the value of map.
Or, instead of changing the "list" and respective code, can you think of any other way to sort the list according to the numbers, and display the string?
Aha I notice you are online, let me post this to you first! Thank you again for your patience and great help！
