为什么我不能使用变量来设置iCal事件？

Question

我可以使用iCal制作新活动。

tell application "iCal"
    tell calendar "Todo"
        set new_event to make new event at end of events
        tell new_event
            set start date to date "Friday, May 6, 2011 4:00:00 PM"
            set end date to date "Friday, May 6, 2011 4:30:00 PM"
            set summary to "Feed ferret"
            set location to "Home 2"
            set allday event to false
            set status to confirmed
        end tell
    end tell
end tell

但是，当我使用变量替换字符串时，我收到了错误。

tell application "iCal"
    tell calendar "Todo"
        set new_event to make new event at end of events
        set m_date to "Friday, May 6, 2011 4:00:00 PM" --> variable m_date
        tell new_event
            set start date to date m_date --> Error
            set end date to date "Friday, May 6, 2011 4:30:00 PM"
            set summary to "Feed ferret"
            set location to "Home 2"
            set allday event to false
            set status to confirmed
        end tell
    end tell
end tell

Answer 1

因为'date'是一个将字符串转换为ical接受的日期格式的函数，所以你只需要在变量中加上'date'

on somefunction()
    set m_date to date "Friday, May 6, 2011 4:00:00 PM"
    my make_todo(m_date)
end somefunction

on make_todo(m_date)
    tell application "iCal"
        tell calendar "Todo"
            set new_event to make new event at end of events

            tell new_event
                set start date to m_date
                set end date to date "Friday, May 6, 2011 4:30:00 PM"
                set summary to "Feed ferret"
                set location to "Home 2"
                set allday event to false
                set status to confirmed
            end tell
        end tell
    end tell
end make_todo
