this link now leads to a suspicious website.
By @Nishant.Kumar.2906
Thank you for the bump, yes, the site is now down and the original link is now redirecting to rubbish.
Here is the code from the original link:
var doc = app.activeDocument;
var filename = doc.name;
var foldername = doc.path.name;
var filepath = doc.path;
var parentfilepath = doc.path.parent
var jpegQuality = 70; // desired quality
var maxfilesize = 512000; // max size in bytes
var dec = 5; // decreasing step
var minimumqual = 50; //minumum desired quality
savefolder = new Folder(filepath + '/BATCH/');
savefolder.create();
saveFile = new File(savefolder + '/' + filename.split('.').slice(0, -1).join('.') + ".jpg");
doc.flatten();
doc.pathItems.removeAll();
doc.channels.removeAll();
function savebatchweb(saveFile, jpegQuality) {
var sfwOptions = new ExportOptionsSaveForWeb();
sfwOptions.format = SaveDocumentType.JPEG;
sfwOptions.includeProfile = true;
sfwOptions.interlaced = 0;
sfwOptions.optimized = true;
sfwOptions.quality = jpegQuality;
doc.exportDocument(saveFile, ExportType.SAVEFORWEB, sfwOptions);
}
savebatchweb(saveFile, jpegQuality);
while (saveFile.length > maxfilesize) {
jpegQuality = jpegQuality – dec;
saveFile = new File(saveFile);
saveFile.remove();
savebatchweb(saveFile, jpegQuality);
if (jpegQuality <= minimumqual) {
break
}
}
doc.close(SaveOptions.DONOTSAVECHANGES); //closes file

While outside of scripting, another batch method is ACR:

Going back to the original post, this isn't covered in standard DOM scripting, nor is it available to the scripting listner plug-in, so AFAIK, the AM scripting alternative isn't possible.
