Script for Open as Layer Without File Extension

Question

I have been searching for a script to open an image and rename a background layer into the file name. I found the below script which works perfectly; however, I'd like to have the layer name without a file extension.

Can someone please help me with editing the script?

Your help will be much appreciated.

/*
@@@BUILDINFO@@@ OpenAsLayer.jsx 1.0.0.0
*/

var begDesc = "$$$/JavaScripts/OpenAsLayer/Description=Assign this to the open document event. This will promote a document with only a background layer to a layer with the document name." // endDesc

// on localized builds we pull the $$$/Strings from a .dat file, see documentation for more details
$.localize = true;

if ( app.documents.length > 0 ) {
var doc = activeDocument;
if ( doc.layers.length == 1 && doc.activeLayer.isBackgroundLayer ) {
doc.activeLayer.isBackgroundLayer = false;
var docNameNoExtension = doc.name;
if (stripExtension) {
var extensionIndex = docNameNoExtension.lastIndexOf (".");
if (extensionIndex != -1) {
docNameNoExtension = docNameNoExtension.substr(0, extensionIndex);
}
}
doc.activeLayer.name = docNameNoExtension;
}
}

Modified code (not exhaustively tested, use at your own risk):

var begDesc = "$$$/JavaScripts/OpenAsLayer/Description=Assign this to the open document event. This will promote a document with only a background layer to a layer with the document name." // endDesc

$.localize = true;
if (app.documents.length > 0) {
    var doc = activeDocument;
    if (doc.layers.length == 1 && doc.activeLayer.isBackgroundLayer) {
        doc.activeLayer.isBackgroundLayer = false;
        var docNameNoExtension = doc.name.replace(/\.[^\.]+$/, '');
    }
}
doc.activeLayer.name = docNameNoExtension;

The script is intended to be driven via the File > Scripts > Scripts Events Manager:

It could be run manually though. Example location of the original script (backup before replacing):

Mac:

/Applications/Adobe Photoshop 2022/Presets/Scripts/Event Scripts Only/Open As Layer.jsx

Win:

C:\Program Files\Adobe\Adobe Photoshop 2022\Presets\Scripts\Event Scripts Only\Open As Layer.jsx
