How to automate exporting different layer combinations?

This is a script I use to export text layers to a file. Note the for loop and test for LayerKind. Your script would have different logic but otherwise be similar.

#target photoshop

textCopier2();

function textCopier2(){

    if(documents.length > 0){

        var originalDialogMode = app.displayDialogs;

        app.displayDialogs = DialogModes.ERROR;

        try{

            var fleLogFile2 = new File('~/Desktop/textExport2.txt');

            fleLogFile2.open('a:');

            for(var j = 0; j < documents.length; j++){

                var docRef = documents;

                var exportLine = docRef.name;

                for(var i = 0; i < docRef.artLayers.length; i++){

                    var LayerRef = docRef.artLayers;

                    if(LayerRef.kind == LayerKind.TEXT){

                        var layerText = LayerRef.textItem.contents;

                        layerText = layerText.replace('\r', ',');

                        layerText = layerText.replace(/,/g, '\r' + exportLine + '\t');

                        exportLine = exportLine + '\t' + layerText;

                        fileWriter2();

                        }

                    }

                }

            function fileWriter2(){

                fleLogFile2.writeln(exportLine);

                exportLine = docRef.name;

                }

            fleLogFile2.close();

            }

        catch(e){

            alert(e + e.line);

            }

        app.displayDialogs = originalDialogMode;

        }

    }
