如何用AppleScript关闭弹窗？PDF转TXT的AppleScript代码技术问询

我之前在做类似的PDF批量转TXT脚本时，也碰到过Acrobat弹出各种确认、警告弹窗的情况，下面给你几个实用的解决思路和代码修改方案：

方案1：用System Events自动识别并点击弹窗按钮 #

这是最直接的方法，通过AppleScript调用System Events来监测弹窗，自动点击确认/取消按钮。你可以把这段代码嵌入到你的循环里，处理每个文件转换时的弹窗：

set homeFolder to path to home folder as text
set sourceFolder to homeFolder & "pdffolder:"
set txtFolder to homeFolder & "txtfolder:"

tell application "Finder"
    set fileSet to get every file of folder sourceFolder whose name ends with ".pdf" -- 只筛选PDF文件，避免非PDF文件触发错误
end tell

activate application "Adobe Acrobat Pro"
-- 先尝试关闭Acrobat的默认警报提示
tell application "Adobe Acrobat Pro"
    set display alerts to false
end tell

repeat with aFile in fileSet
    set currentFile to aFile as text
    set currentFileName to name of aFile
    set outFile to txtFolder & text 1 thru -5 of currentFileName & ".txt"
    
    -- 打开PDF并执行转换（补全你原有的转换逻辑）
    tell application "Adobe Acrobat Pro"
        open currentFile
        export active document to file outFile as text
        close active document saving no
    end tell
    
    -- 监测并关闭可能出现的弹窗
    tell application "System Events"
        -- 替换成你实际遇到的弹窗标题，比如中文环境的"Adobe Acrobat"或"警告"
        if exists window "Adobe Acrobat" of application process "Adobe Acrobat" then
            try
                click button "确定" of window "Adobe Acrobat" of application process "Adobe Acrobat"
            end try
        end if
        -- 可根据实际弹窗添加更多判断
        if exists window "警告" of application process "Adobe Acrobat" then
            try
                click button "确定" of window "警告" of application process "Adobe Acrobat"
            end try
        end if
    end tell
end repeat

方案2：修改Adobe Acrobat偏好设置，从根源避免弹窗 #

很多弹窗是可以通过Acrobat的内置设置关闭的，比如保存提示、OCR自动检测提示等，你可以在脚本开头先配置这些选项，从根源减少弹窗：

tell application "Adobe Acrobat Pro"
    -- 全局关闭警报弹窗
    set display alerts to false
    -- 关闭保存时的确认提示
    set save without prompt to true
    -- 如果涉及扫描件PDF，关闭自动OCR提示
    tell preferences
        set auto OCR to false
    end tell
end tell

这个方法更高效，推荐优先尝试，能大幅减少后续的弹窗处理逻辑。

方案3：添加错误捕获，处理弹窗引发的脚本中断 #

有时候弹窗会直接触发AppleScript的错误中断，你可以用try...on error块捕获错误，并针对性处理：

repeat with aFile in fileSet
    set currentFile to aFile as text
    set currentFileName to name of aFile
    set outFile to txtFolder & text 1 thru -5 of currentFileName & ".txt"
    
    try
        tell application "Adobe Acrobat Pro"
            open currentFile
            export active document to file outFile as text
            close active document saving no
        end tell
    on error errMsg number errNum
        -- -1708是常见的用户交互阻塞错误码，可根据实际情况调整
        if errNum = -1708 then
            tell application "System Events"
                -- 直接点击当前弹窗的确认按钮
                click button "确定" of window 1 of application process "Adobe Acrobat"
            end tell
            -- 重新尝试处理当前文件
            tell application "Adobe Acrobat Pro"
                open currentFile
                export active document to file outFile as text
                close active document saving no
            end tell
        end if
    end try
end repeat

关键注意事项 #

• 务必给脚本和Acrobat开启辅助功能权限：在系统偏好设置→安全性与隐私→隐私→辅助功能中，添加Script Editor和Adobe Acrobat程序，否则System Events无法控制弹窗。
• 弹窗的标题和按钮名称要和你实际遇到的一致（比如英文环境是"OK"，中文是"确定"），需要对应修改代码里的文字。
