applescript - 将网页内容保存为 PDF 的 AppleScript 引发错误：“无法将窗口“保存”设置为……”

Question

我正在尝试将我在 Safari 中打开的 URL 的 Web 内容保存为 PDF。我能够通过 Automator 成功实现它，但我想要一个 AppleScript 来做到这一点。

这是我试图运行的脚本，它给我一个错误：

error "System Events got an error: Can’t set window \"Save\" to \"~/Desktop/Reports/\"." number -10006 from window "Save"

我做的步骤：

1. 为另存为 PDF 创建了快捷方式...
2. 打开有一些网页内容的 Safari

3. 运行以下脚本：

   set destination_folder to "/Users/swatt/Desktop/Reports"
   tell application "System Events"
       keystroke "p" using {command down} -- activate print menu item
       delay myDelay
       keystroke "p" using {command down, option down, control down} -- to select the Save as PDF… option
       keystroke "g" using {shift down, command down} -- to select the folder location
   
       set value of text field 1 of sheet of window "Save" to destination_folder
   
       -- Now click the Go button
       click button "Go" of sheet of window "Save"
       delay myDelay
   
       -- Now that we are in our desired folder, set the file name and save
       set value of text field 1 of window "Save" to "TestResults.pdf"
   
       --click button "Save" of window "Save"
       click button "Go"
   end tell
   

Answer 1

键盘快捷键适用于最前面的应用程序，但对于 UI 元素（窗口、文本字段等），您必须指定进程

tell application "System Events"
    tell application process "Safari"
        keystroke "p" using {command down} -- activate print menu item
        --  other lines
        --
    end tell
end tell
