// 打开一个对话框，让用户选择保存文件的文件夹
var folder = Folder.selectDialog("请选择保存文件的文件夹");

if (folder !== null) {
    
    
    // 遍历原始文档的所有图层
    for (var i = 0; i < originalDoc.artLayers.length; i++) {
    
    
        var layer = originalDoc.artLayers[i];
        originalDoc.activeLayer = layer; // 设置活动图层
        layer.copy(); // 复制图层内容

        // 创建一个临时文档用于存储每个图层
        var tempDoc = app.documents.add(originalDoc.width, originalDoc.height, originalDoc.resolution, "temp", NewDocumentMode.RGB, DocumentFill.TRANSPARENT);
        tempDoc.paste(); // 粘贴复制的内容

        // 保存图层为PNG
        var outputFile = new File(folder + '/' + layer.name + '.png');
        var pngOptions = new PNGSaveOptions();
        tempDoc.saveAs(outputFile, pngOptions, true);

        // 关闭临时文档并不保存更改
        tempDoc.close(SaveOptions.DONOTSAVECHANGES);
