Save for web jpg , file name the active layer name

Thank you, Conrad, for your reply

Your suggestion is not fits my needs  unfortunately.

This is my final  solution,  a beginner code,  but it works

// Save for web, jpg
// file name =  layer parent group name 
#target photoshop
var outputFolder = Folder.selectDialog("Choose a folder to save your  file.");
var theLayer = activeDocument.activeLayer;
var theName = theLayer.parent.name;
var doc = app.activeDocument;
var activeLayer = doc.activeLayer;
var newName = theName+'.jpg';
//jpg options
var jpgoptions = new ExportOptionsSaveForWeb();
jpgoptions.interlaced = false;
jpgoptions.quality = 50;
jpgoptions.includeProfile = false;
jpgoptions.format = SaveDocumentType.JPEG; // Document Type
doc.exportDocument(File(doc.path+'/'+newName),ExportType.SAVEFORWEB,jpgoptions);
