Is there any way to get frame count of timeline animation using JSX script?

[salithan73779666]

I want to extract frame count using JSX script?
I have used following code. But it seems not sharp as expected (In case of decimal point of seconds it seems not good)

function getTimelineLength() {

    var ref = new ActionReference();

    ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('duration'));

    ref.putClass(stringIDToTypeID('timeline'));

    var desc = new ActionDescriptor();

    desc.putReference(charIDToTypeID('null'), ref);

    var TC = executeAction(charIDToTypeID('getd'), desc, DialogModes.NO);

    TC = TC.getObjectValue(stringIDToTypeID('duration'));

    var M = 0;

    try { M = TC.getInteger(stringIDToTypeID('minutes')); } catch (e) { }

    var S = 0;

    try { S = TC.getInteger(stringIDToTypeID('seconds')); } catch (e) { }

    var F = TC.getInteger(stringIDToTypeID('frame'));

    var FR = TC.getInteger(stringIDToTypeID('frameRate'));

    var A = new Array();

    A.push([[M], [S], [F], [FR]]);

    return A;

}

//option 1

var frameCount = timeLineInfo[0][2]  ( But this returns "0" value with newly opened document)

//option 2

var timeLineInfo =  getTimelineLength()

var frameCount = timeLineInfo[0][1] * timeLineInfo[0][3]  ( This is not returns correct value with decimal value of seconds )

Anyone have a better solution?

// determine durations in a frame animation;

if (app.documents.length > 0) {
var myDocument = app.activeDocument;
var theNumbers = new Array;
var theCounter = 1;
var theCheck = selectFrame (theCounter);
//var theFrameCount = GetFrameCount();
while (theCheck != false) {
var theDur = getFrameDelay(theCounter);
theCounter++;
theNumbers.push(theDur);
var theCheck = selectFrame (theCounter);
};
alert ("durations\n"+theNumbers.join("\n"))
};

This panel works for frame animation, not the video style method. As @c.pfaffenbichler states, an simple example file would help pinpoint possible issue
