var doc = app.activeDocument;
var textFrames = doc.textFrames;
var numTextFrames = textFrames.length; for (var i = 0; i < numTextFrames; i++) { var tf = textFrames[i]; if (tf.kind == TextType.AREATEXT && tf.textPath.contents.length > 0 && tf.textPath.overflows) { alert("Overset text detected in text frame " + (i+1)); } }

can anyone here help me on this!

This returns error

or any other way to alert

Try this

var doc = app.activeDocument;
var textFrames = doc.textFrames;
var numTextFrames = textFrames.length;
for (var i = 0; i < numTextFrames; i++) {
    var tf = textFrames[i];
    if (tf.kind == TextType.AREATEXT &&
        tf.contents.length > 0 &&
        overflows(tf)) {
            alert("Overset text detected in text frame " + (i + 1));
            // tf.selected = true;
    }
}

function overflows(tf) {
    var lastLine = tf.lines[tf.lines.length - 1];
    var textRange1 = lastLine.contents;
    var textRange2 = "";
    var i = tf.characters.length - 1;
    var difference = (tf.characters.length - lastLine.contents.length) - 1;
    var lastChar = tf.characters[tf.characters.length - 1].contents;
    for (var j = 0; j < 32; j++) {
        if (lastChar == String.fromCharCode(j) && lastChar != "\t") {
            i--, difference--;
            break;
        }
    }
    for (i; i > difference; i--) {
        textRange2 = tf.characters[i].contents + textRange2;
    }
    return textRange1 != textRange2;
}

An alternative function (not rigorously tested).

var doc = app.activeDocument;
var textFrames = doc.textFrames;
var numTextFrames = textFrames.length;
for (var i = 0; i < numTextFrames; i++) {
    var tf = textFrames[i];
    if (tf.kind == TextType.AREATEXT &&
        tf.contents.length > 0 &&
        overflows(tf)) {
            alert("Overset text detected in text frame " + (i + 1));
    }
}

function overflows(tf) {
    var lastLine = tf.lines[tf.lines.length - 1];
    var textRange1 = lastLine.contents;
    var textRange2 = "";
    for (var i = tf.characters.length - 1;
        i > (tf.characters.length - lastLine.contents.length) - 1;
        i--) {
        textRange2 = tf.characters[i].contents + textRange2;
    }
    return textRange1 != textRange2;
}

    @m1b @femkeblanco 

    Thankyou both

    I am trying and testing both

    @m1b 

    One thing with the first method is the layers should be unlocked, also the sublayers, sub groups.
    sometimes with multiple elements, it returns an error, but I am analysing it.

    @femkeblanco 

    With your method as @m1b said is clear but i tried in multiple documents with multiple elements, it also alerts for multiple frames which does n't have any overset warning.

    Hi @femkeblanco, I tried your updated version and it worked perfectly on the sample file. As far as I can tell, you solved the problem, and when I tried I don't think I really even understood the issue of the extra linefeed correctly, so thank you for showing the way!

     

    @thirukumarans77083 You may replace my version with this one if you like. Personally I prefer @femkeblanco's version because it does no DOM manipulation (mine makes a temp layer and duplicate textframe), but in practice they are probably indistinguishable to the user. Bear in mind that you will need to deal with the locked or hidden layers/items problem by setting those to false (see example in my script above).

    @m1b @femkeblanco Thank you very much, I have tested it working well on the documents shared, but some of the tested files still show the display alert of the textbox which doesn't have the overset warning.

    Hi @thirukumarans77083, I've put together a function to do this, which I found in another area on this forum. See code for link. - Mark

    var doc = app.activeDocument;
var textFrames = doc.textFrames;
var numTextFrames = textFrames.length;
for (var i = 0; i < numTextFrames; i++) {
    var tf = textFrames[i];
    if (textFrameIsOverset(tf)) {
        alert("Overset text detected in text frame " + (i + 1) + ' ' + tf.name);
    }
}
