Turn on Auto-Size on all text frames that contain a Character Style

Hi @Rogerio5C09, how about this?

function main() {

    var doc = app.activeDocument;

    // reset grep prefs
    app.findGrepPreferences = NothingEnum.NOTHING;
    app.changeGrepPreferences = NothingEnum.NOTHING;

    // find criteria
    app.findGrepPreferences.appliedCharacterStyle = 'MyCharStyle';

    var found = doc.findGrep();

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

        for (var j = 0; j < found[i].parentTextFrames.length; j++) {

            var frame = found[i].parentTextFrames[j];

            if (frame.isValid) {
                frame.textFramePreferences.autoSizingReferencePoint = AutoSizingReferenceEnum.TOP_CENTER_POINT;
                frame.textFramePreferences.autoSizingType = AutoSizingTypeEnum.HEIGHT_ONLY;
            }

        }

}; // end main

app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Set Autosizing');
