使用选择列表而不是收件箱时出现 Applescript 错误 1700

Question

我是 AppleScript 的新手，我遇到了一个简单的问题：

tell application "Mail"
    -- this works:
    set mylist to subject of every message of inbox

    -- but why this does not work? (error 1700)
    set mylist to subject of every message of selection

end tell

Answer 1

错误 1700 表示 "Can’t make «script» into type item"。尝试以列表形式遍历所选内容：

set mylist to {}
repeat with amessage in (selection as list)
    copy subject of amessage to end of mylist
end repeat
