Question

我想在特定时间播放iTunes文件夹播放列表，我自己想出了这个部分。但事实是，我想在之后将iTunes切换到迷你播放器。所以这是代码

tell application "iTunes" to quit
delay 5

tell application "iTunes"
    reopen
    activate
    set song repeat to all
    set shuffle enabled to true
    set sound volume to 35
    delay 5
    get name of AirPlay devices
    set selected of AirPlay device "Airport Express" to true
    play playlist "mom's music"
end tell

delay 20

-- here comes the part I don't get

tell application "System Events"
    tell process "iTunes"
        set frontmost to true
        if title of window 1 is "미니 플레이어" then
            click menu item 9 of menu 9 of menu bar 1
            delay 5
            click menu item 9 of menu 9 of menu bar 1
        else
            click menu item 9 of menu 9 of menu bar 1
        end if
    end tell
end tell

不要介意上半部分。请查看“系统事件”部分。

当屏幕保护程序没有运行时，它确实可以正常工作，但是当屏幕保护程序运行时却没有，但我无法弄清楚我错过了什么。

那么，在屏幕保护程序下运行applescript还有另一个限制我不知道吗？任何建议，将不胜感激。感谢。

当我按下“窗口”菜单项时，我注意到，iTunes（主要的）窗口消失了。这是否意味着我必须超越屏幕保护程序才能通过AppleScript对Windows做任何事情？

Answer 1

当屏幕保护程序运行时，脚本仍会运行但不会处理某些事件。解决方法是在运行任何依赖于UI脚本的代码之前停止屏幕保护程序。在这种情况下。

示例：

tell application "System Events"
    key code 53 -- # Esc key.
    delay 1 - # Adjust as necessary, the screen saver needs to have stopped before continuing.
    tell process "iTunes"
        set frontmost to true
        if title of window 1 is "미니 플레이어" then
            click menu item 9 of menu 9 of menu bar 1
            delay 5
            click menu item 9 of menu 9 of menu bar 1
        else
            click menu item 9 of menu 9 of menu bar 1
        end if
    end tell
end tell

Answer 2

试试这个版本

try
    tell application id "com.apple.ScreenSaver.Engine" to quit
end try

tell application "System Events"
    tell process "iTunes"
        set frontmost to true
        if title of window 1 is "미니 플레이어" then
            click menu item 9 of menu 9 of menu bar 1
            delay 5
            click menu item 9 of menu 9 of menu bar 1
        else
            click menu item 9 of menu 9 of menu bar 1
        end if
    end tell
end tell

激活屏幕保护程序时运行applescript
