How to determine if a page is blank?

I use a series of dependent functions to determine if a page is empty. The example here tests the current page, but you can expand it to test all of the pages in a document. Note that this code considers a page empty if there is nothing in its Flow A text frame. Technically, there could be other text frames or graphics directly on the page and this script doesn't check for this. But in most cases, you are looking for a page with nothing in its Flow A text frame so this will work fine. Please let me know if you have any questions or comments.

#target framemaker
var doc = app.ActiveDoc;
// Test the current page.
var page = doc.CurrentPage;
// true for empty; false for not empty.
alert (pageIsEmpty (page));
function pageIsEmpty (page) {
    
    var textFrame;
    
    textFrame = getTextFrame (page, "A");
    if (textFrame) {
        if (textFrameIsEmpty (textFrame) === true) {
            return true;
        }
    }
    return false;
}
function getTextFrame (page, flow) {
    
    var frame, graphic;
    
    frame = page.PageFrame;
    graphic = frame.FirstGraphicInFrame;
    while (graphic.ObjectValid () === 1) {
        if (graphic.constructor.name === "TextFrame") {
            if (graphic.Flow.Name === flow) {
                return graphic;
            }
        }
        graphic = graphic.NextGraphicInFrame;
    }
}
function textFrameIsEmpty (textFrame) {
    
    if (textFrame.LastPgf.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastCell.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastAFrame.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastFn.ObjectValid () === 1) {
        return false;
    }
    else {
        return true;
    }
}
