通过Applescript抛出错误获取活动窗口，“无法获得进程的窗口1”

Question

剧本：

global frontApp, frontAppName, windowTitle

set windowTitle to ""
tell application "System Events"
    set frontApp to first application process whose frontmost is true
    set frontAppName to name of frontApp
    tell process frontAppName
        tell (1st window whose value of attribute "AXMain" is true)
            set windowTitle to value of attribute "AXTitle"
        end tell
    end tell
end tell

return {frontAppName, windowTitle}

它可以工作一些时候，但其他时候我得到的东西如下：[2021-03-15 19:43:53.947] [error] Error: 339:344: execution error: System Events got an error: Can’t get window 1 of process "Adobe Premiere Pro 2020" whose value of attribute "AXMain" = true. Invalid index. (-1719)

有什么想法吗？

谢谢!

添加到您的repeat loop代码中的下面这个AppleScript代码应该可以做到这一点

global frontApp, frontAppName, windowTitle

set windowTitle to ""
tell application "System Events"
    set frontApp to first application process whose frontmost is true
    set frontAppName to name of frontApp
    tell process frontAppName
        repeat until exists of ¬
            (1st window whose value of attribute "AXMain" is true)
            delay 0.1
        end repeat
        tell (1st window whose value of attribute "AXMain" is true)
            set windowTitle to value of attribute "AXTitle"
        end tell
    end tell
end tell

return {frontAppName, windowTitle}
