DriveApp父文件夹 [英] DriveApp parent folder

问题描述

There is something i just don't understand about the logic in DriveApp scripting..the most basic example:

有些东西我只是不明白DriveApp脚本中的逻辑。 driveFile = DriveApp.getFileById（id）; //有意义，我可以访问文件
var name = driveFile.getName（）; //很有意义，我很容易得到文件名

var parentFolder = driveFile.getParents（）; //我得到folderIterator
var parentFolderName = //我如何得到这个？

var driveFile = DriveApp.getFileById(id); // makes sense, i can access the file var name = driveFile.getName(); // makes sense, i easily get the file name var parentFolder = driveFile.getParents(); // i get folderIterator var parentFolderName = // how do i get this???

如果我查看文档文件夹，迭代器只允许我访问它：

If i look the documentation folder iterator only lets me access this:

1. getContinuationToken（）String获取一个令牌，用于稍后恢复此迭代。
   
2. hasNext（）Boolean确定是否调用next（）将返回一个项目。


3. next（）文件夹获取文件或文件夹集合中的下一个项目。

如何获取该特定父文件夹的名称？

How do i get the name for that specific parent folder?

推荐答案

有多个父文件夹，即使只有一个父文件夹，父母仍会像列表或数组一样返回父母文件夹，并且必须循环才能检索单个父母

because files can have more than one parent folder the parents are returned like a list or array, even if there is only one parent folder, and you have to cycle through to retrieve individual parents

// Log the name of every parent folder
 var driveFile = DriveApp.getFileById(id); 
 var parentFolder = driveFile.getParents();
 while (parentFolder.hasNext()) {
   var folder = parentFolder.next();
   Logger.log(folder.getName());
 }

如果您确定该文件只有一位父母可以做类似：

if you were sure that the file has only one parent you could do something like:

var parentFolder = driveFile.getParents();
var folderName =parentFolder.next().getName()
