Google文档中的自动增量文件名？

Question

我如何为我的所有帐户添加文档功能，当我打开新文档的文件时，它想找到我现在的文件夹+最后文件名并增加1并保存。

对于名为“无标题文档”的默认Google Doc保存文档，但我希望将其保存：

folder_1.1001.doc folder_1.1002.doc

如果我在下一个Folder2中创建文件：

folder_2.001.doc folder_2.002.doc。

我的坏代码：

// Show current folder name & root folder name
function makeFilename() {

  // Get current folder name
  var ui = DocumentApp.getUi();
  thisFileId = DocumentApp.getActiveDocument().getId();

  var thisFile = DriveApp.getFolderById(thisFileId);
  var parentFolder = thisFile.getParents();
  var currentFolderName = parentFolder.next();
  ui.alert(currentFolderName);

  // get all files in currentFolderName
  var files = parentFolder;
  while (files.hasNext()) {
    var file = files.next();  
   //  Logger.log(file.getName());
   DocumentApp.getUi().alert(file.getName());
  }
}

这是一个示例代码：

// Show current folder name 
function makeFilename() {

  // Get current file name
  const ui = DocumentApp.getUi(),
    doc = DocumentApp.getActiveDocument(), //Added
    thisFileId = doc.getId(),
    thisFileName = doc.getName();

  const thisFile = DriveApp.getFileById(thisFileId);//Modified from getFolderById
  const parentFolder = thisFile.getParents();
  const currentFolder = parentFolder.next();//Modified from currentFolderName
  const currentFolderName = currentFolder.getName();//Added
  //ui.alert(currentFolderName);

  /*Store a init file in root to getLatestFileNumber*/
  var initIter = DriveApp.getFilesByName(currentFolderName + 'init000'),
    initBool = initIter.hasNext(),
    init;
  if (!initBool) {
    init = DriveApp.createFile(currentFolderName + 'init000', '0');
  } else {
    init = initIter.next();
  }

  /*Get current Number and format it to 4 digits*/
  var currentNum = init.getBlob().getDataAsString() * 1 + 1,
    formatNum = ('00000' + currentNum).substr(-4);

  /*If filename already contains folderName, do nothing*/
  if (!(thisFileName.search(currentFolderName) + 1)) {
    doc.setName(currentFolderName + formatNum).saveAndClose();
    init.setContent(currentNum);
  }
}
