How can I get a list of selections in a select box? (Script on Page 387 of Acrobat JavaScript Scripting Refence not Working)

[Guest]

I am trying to use the well known code on page 387 of Acrobat JavaScript Scripting Reference:

var f = this.getField("myList");

var a = f.currentValueIndices;

if (typeof a == "number") // a single selection

console.println("Selection: " + f.getItemAt(a, false));

else {// multiple selections

console.println("Selection:");

for (var i = 0; i < a.length; i ++)

console.println(" " + f.getItemAt(a, false));

}

However, in my code, it is not working (please see: <ACRO_source>Room:Keystroke</ACRO_source> at the bottom of the listing).  Most of the time it just produces the text:

Selection: FIRST_ELEMENT

Sometimes it produces a short list, but never the correct list of the selected elements in the select box.

//<Document-Level>

//<ACRO_source>Main</ACRO_source>

//<ACRO_script>

/*********** belongs to: Document-Level:Main ***********/

var buildingRoom = {};

var oFile = this.getDataObjectContents("export.csv");

var cFile = util.stringFromStream(oFile, "utf-8");

var arr = cFile.replace(/\r\n/g, ",").split(",");

var building;

var room;

for(var i = 0; i < arr.length-1; i++)

{

   building = arr.replace(/\r?\n|\r|"/g,'');

   if(!(building in buildingRoom))

        buildingRoom[building]=[];

   room = arr[++i].replace(/\r?\n|\r|"/g,'');

   buildingRoom[building].push([room,room]);

}

var buildingArr = Object.keys(buildingRoom);

var buildingArrItems = [];

for(var i = 0; i < buildingArr.length; i++)

    buildingArrItems.push([buildingArr,buildingArr]);

this.getField("Room").setItems(buildingRoom[Object.keys(buildingRoom)[0]]);

this.getField("Building").setItems(buildingArrItems);

var f = this.getField("Room");

//</ACRO_script>

//</Document-Level>

//<AcroForm>

//<ACRO_source>Building:Keystroke</ACRO_source>

//<ACRO_script>

/*********** belongs to: AcroForm:Building:Keystroke ***********/

if(event.willCommit)

{

//console.println("buildingEvent");

//console.println(event.value);

//console.println(buildingRoom[event.value]);

this.getField("Room").clearItems();

this.getField("Room").setItems(buildingRoom[event.value]);

}

//</ACRO_script>

//</AcroForm>

//<AcroForm>

//<ACRO_source>Room:Keystroke</ACRO_source>

//<ACRO_script>

/*********** belongs to: AcroForm:Room:Keystroke ***********/

var a = f.currentValueIndices;

if (typeof a == "number") // a single selection

console.println("Selection: " + f.getItemAt(a, false));

else {// multiple selections

console.println("Selection:");

for (var i = 0; i < a.length; i ++)

console.println(" " + f.getItemAt(a, false));

}

//</ACRO_script>

//</AcroForm>

I don't see where you defined the value of the "f" parameter...

It is defined at document level.

I placed a button on the page and configured it to execute the code on mouse up and it works as expected.  It appears that putting the code in the keystroke event itself isn't how it was supposed to be used.  I should have figured this out yesterday evening, as I was observing the phenomenon where I see different results under seemingly identical circumstances, which indicates it is a timing issue.

During the keystroke event you get the old selection with your code, not the actual.
