AppleScript - 获取文件夹中唯一文件的名称？

Question

下面的AppleScript代码获得最后添加的文件，

tell application "Finder" 
    set latestFile to item 1 of (sort (get files of (path to downloads folder)) by creation date) as alias 
    set fileName to latestFile's name 
end tell

但是，如果该文件夹中只有一个文件失败。如何解决这个问题？

Answer 1

该脚本应该与一个文件一起使用。但是如果有没有文件，则会报错。

您可以用try块

tell application "Finder" 
    try 
     set latestFile to item 1 of (sort (get document files of (path to downloads folder)) by creation date) as alias 
     set fileName to latestFile's name 
    end try 
end tell
