[Jing Long]

I want to convert this code to plugin how can I do?

#target photoshop

function findLayerSetByName(name) {

    var layerSets = app.activeDocument.layerSets;

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

        if (layerSets[i].name === name) return layerSets[i];

    }

    return null;

}

function exportGroupAsWebJPG(groupName, baseName, exportFolder) {

    var doc = app.activeDocument;

    // First hide all language groups

    var kh = findLayerSetByName("kh");

    var vn = findLayerSetByName("vn");

    var eng = findLayerSetByName("eng");

    if (kh) kh.visible = false;

    if (vn) vn.visible = false;

    if (eng) eng.visible = false;

    // Show only current group

    var targetGroup = findLayerSetByName(groupName);

    if (!targetGroup) {

        alert("Group '" + groupName + "' not found.");

        return;

    }

    targetGroup.visible = true;

    // Set export options

    var exportOptions = new ExportOptionsSaveForWeb();

    exportOptions.format = SaveDocumentType.JPEG;

    exportOptions.includeProfile = false;

    exportOptions.interlaced = false;

    exportOptions.optimized = true;

    exportOptions.quality = 100;

    // Export

    var fileName = groupName + "_" + baseName + ".jpg";

    var file = new File(exportFolder + "/" + fileName);

    doc.exportDocument(file, ExportType.SAVEFORWEB, exportOptions);

}

function exportAllLanguageGroups() {

    var doc = app.activeDocument;

    var baseName = doc.name.replace(/\.[^\.]+$/, '');

    var exportPath = Folder.selectDialog("Choose export folder");

    if (!exportPath) return;

    var languages = ["kh", "vn", "eng"];

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

        exportGroupAsWebJPG(languages[i], baseName, exportPath);

    }

    alert("Exported all versions successfully!");

}

exportAllLanguageGroups();
