如何获取文件夹的第一个子路径（当第一个子路径是文件夹时）？

假设你有...

Folder 1 ¬
  File 1
  File 2
  Folder 2 ¬
    File A
    File B
    File C
    File D

用例：

我 select 一批文件夹，都与 Folder 1 处于同一级别： set foldersToProcess to choose folder with multiple selections allowed

然后，我遍历每个排队的文件夹 foldersToProcess，在此过程中我想查看 Folder 1 的第一个子文件夹（即 Folder 2），每一次。

我该怎么做？

Answer 1

您应该使用 try block 因为可能某些选定的文件夹根本不包含子文件夹。因此，如果没有 try 块，它会在请求空列表的文件夹 1 时抛出错误。

获取第一个文件夹作为系统事件的文件夹引用:

set chosenFolders to (choose folder with multiple selections allowed)

set firstFolders to {}
repeat with anAlias in chosenFolders
    try
        tell application "System Events" to ¬
            set end of firstFolders to folder 1 of folder (anAlias as text)
    end try
end repeat

要获取第一个文件夹的 HFS 路径，请编辑相应的代码行：

tell application "System Events" to ¬
            set end of firstFolders to path of folder 1 of folder (anAlias as text)

要获取第一个文件夹的 Posix 路径，编辑相应的代码行：

tell application "System Events" to ¬
            set end of firstFolders to POSIX path of folder 1 of folder (anAlias as text)
