AppleScript启用编辑框

Question

我的脚本从AppA获取一些文本并将其粘贴到AppB上的文本编辑中。当AppB启动时（通过脚本），文本编辑被禁用，当用户执行操作时变为启用状态。该行动需要保持手动。

该脚本在用户有时间处理任何事情之前执行错误。我的想法是检查是否启用了编辑，但是出现此错误。 “无法获得应用程序”系统事件“的AppB的AppB窗口>”AppB“，它只会抛出一次错误。

如何避免错误？尝试阻止只吃错误更好？

on idle 
tell application "System Events" to set AppAIsOpen to (application process "AppA" exists) 
if (AppAIsOpen) then 
    set AppAWasOpen to true 
    tell application "AppA" 
    set hdg to TxRprt 
    set beam to hdg as string 
    end tell 
    if ((count beam) < 3) then set beam to text -3 thru -1 of ("000" & beam) 
    if (beam is not previousText) then 
     tell application "AppB" to launch 
     tell application "System Events" 
      tell application process "AppB" 
     if text field 1 of window "AppB" is enabled then -- error here 
      set value of text field 1 of window "AppB" to beam --or here 
     end if 
     end tell 
    end tell 
    set previousText to beam 
     end if 
    return checkInterval 
else if (AppAgWasOpen) then 
    quit 
     return 1 
end if 

结束闲置

通常我进入一个重复循环并为您的文本字段（或任何界面元素），试图用它做任何事情之前变得可用。这样的事情会工作，并应消除你的错误

不是冰我也加入了一个时间检查这个过程，以便我不会陷入重复循环。在这种情况下，我最多等待5秒以使文本字段可用。

tell application "System Events" 
    -- wait for the text field to become available 
    set startTime to current date 
    repeat until exists (text field 1 of window "AppB" of application process "AppB") 
     if (current date) - startTime is greater than 5 then 
      error "Could not find text field 1 of window AppB of application process AppB" 
      exit repeat 
     end if 
     delay 0.2 
    end repeat 

    tell application process "AppB" 
     if text field 1 of window "AppB" is enabled then -- error here 
      set value of text field 1 of window "AppB" to beam --or here 
     end if 
    end tell 
end tell
