How to Bypass "JPEG Options" when saving JPG Files (under Photoshop v23.1)

jpg and psd/psb are different file formats, so I wonder how you arrived at those conclusions. 

Fabulous!!! 😄

OK it appears that I needed to use a "switch" statement inside the while loop, my first use of switch! Anyway, here is a slightly refined v1.1 of the previous script, which accounts for "edge cases" of non-standard JPEG extension use:

        uuid[14] = '4'; // version 4
        for (var i = 0; i < 36; i++) {
            if (!uuid[i]) {
                r = 0 | rnd() * 16;
                uuid[i] = chars[(i == 19) ? (r & 0x3) | 0x8 : r & 0xf];
            }
        }
        return uuid.join('');
    }

    app.activeDocument.artLayers.add().name = "randomLyrName = " + uuid();
    app.activeDocument.activeLayer.remove();

    if (app.activeDocument.path) {
        app.activeDocument.close(SaveOptions.SAVECHANGES);
    }
}

// SAVE MODIFIED OR UNMODIFIED .JPG FILES USING NEW QUALITY LEVEL & OTHER OPTIONS
function jpg() {
    var saveFileJPG = new File(app.activeDocument.path + '/' + app.activeDocument.name);
    saveJPG(saveFileJPG);
    app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}

// JPEG SAVE OPTIONS
function saveJPG(saveFileJPG) {
    var jpgOptions = new JPEGSaveOptions();
    jpgOptions.formatOptions = FormatOptions.STANDARDBASELINE;
    jpgOptions.embedColorProfile = true;
    jpgOptions.matte = MatteType.NONE;
    jpgOptions.quality = 12;
    app.activeDocument.saveAs(saveFileJPG, jpgOptions, true, Extension.LOWERCASE);
}

You can use the following script to save and close all open, previously saved files with a .jpg file extension. You can change the fixed quality value from 12 to something more appropriate.

This script presumes that all open files have a .jpg extension and have been previously saved, the script will stop if a file does not meet these conditions

NOTE: I have been trying to add seamless options for gracefully handling files with the following criteria –

* Unsaved files (skip over and continue loop)

* Files without a .jpg extension (skip over and continue loop)

* Files with a non-standard .jpeg extension (skip over and continue loop or alert and handle  the save manually)

However, I keep hitting a brick wall where the script fails to continue looping over open files once one of these exceptions have been hit. Therefore the script will only work as intended if all open files have the .jpg extension. I thought that it was better to post the script as is, rather than waiting for a version that handled these exceptions when they may not be an issue.

An action can record the desired JPEG save settings with a fixed save path location, just don't change the filename when recording. This is not useful unless you always open and save to the same location, such as the desktop. Actions have limitiations.

A script could be used to save all open documents to their original location, with their original name with your desired JPEG settings without a dialog. If they were not originally JPEG then a new file would be created, otherwise JPEG files would be overwritten.

The files that close without dialog were most likely previously saved by Photoshop and so the JPEG options are known. The files that bring up the dialog most likely were never saved from Photoshop, so the JPEG options are not known.

Please provide meaningful information. 

How do you crop? »Delete Cropped Pixels« or not? 

If not then a jpg cannot be saved because it cannot contain any Layers except a Background Layer.
