Question

我正在尝试制作一个AppleScript，让我将桌面图片更改为硬盘上文件夹中的随机图片

tell application "Finder"
    set desktopPictures to folder "Path:To:Desktop:Pictures:"
set fileList to name of every file of desktopPictures
set theNum to random number from 1 to (count fileList) with seed ((time of (current date)) * 4)
set fileName to item theNum of fileList
set desktop picture to file fileName in desktopPictures
end tell

到目前为止它完美运行，我唯一的问题是当我连接另一台显示器时，他的桌面图片不会改变。我尝试使用the following code I found making a web search

解决此问题

tell application "Finder"
    set desktopPictures to folder "Path:To:Desktop:Pictures:"
    set fileList to name of every file of desktopPictures
    set theDesktops to a reference to every desktop 
    repeat with aDesktop in theDesktops
        set theNum to random number from 1 to (count fileList) with seed ((time of (current date)) * 4)
        set fileName to item theNum of fileList
        set picture of aDesktop to file fileName in desktopPictures
    end repeat
end tell

但是这段代码无法编译，因为我收到语法错误：

Expected class name but found property. 第4行突出显示desktop

您已从找到的代码中省略了tell应用程序“System Events”块。

在Applescript中，某些命令存在于特定应用程序的字典中，必须使用“tell application”块进行引用。在这种情况下，“每个桌面”调用都在“系统事件”应用程序中。

试试这个。

tell application "Finder"
    set desktopPictures to folder "Path:To:Desktop:Pictures:"
    set fileList to name of every file of desktopPictures
    tell application "System Events"
        set theDesktops to a reference to every desktop
    end tell
    repeat with aDesktop in theDesktops
        set theNum to random number from 1 to (count fileList) with seed ((time of (current date)) * 4)
        set fileName to item theNum of fileList
        set picture of aDesktop to file fileName in desktopPictures
    end repeat
end tell
