如何解决“不能使类型日期缺少值”

Question

我正在尝试列出缺少截止日期的应用程序中的所有提醒，但出现上述错误。任何机构都知道在这种情况下如何检查缺失值？

代码如下：

set remListOut to ""
set curDate to current date

tell application "Reminders"
    activate
    repeat with theRemList in remLists
        tell list "@Call"
            set remList to (every reminder whose due date is missing value)
            repeat with theRem in remList
                log (get properties of theRem)
                set remListOut to remListOut & name of theRem & "
"
            end repeat
        end tell
    end repeat
end tell
return remListOut

Answer 1

我认为这是一个错误，代码正确。

作为解决方法，请使用第二个循环

set remListOut to ""
set curDate to current date

tell application "Reminders"
    repeat with aList in lists
        repeat with aReminder in reminders of aList
            if due date of aReminder is missing value then
                log (get properties of aReminder)
                set remListOut to remListOut & name of aReminder & return & tab & tab
            end if
        end repeat
    end repeat
end tell
return remListOut
