Question

我是Apple脚本的新手，我有一个简单的苹果脚本，在下面 -

display dialog "Enter Your User Name:" default answer ""
set theUser to the text returned of the result

现在，如果用户未输入任何内容并点击OK，我会检查

if theUser = "" then
    display dialog "User name is mandatory" buttons {"OK"} with title "Missing parameter" with icon "stop"
    set theError to button returned of the result
    if theError is "OK" then quit
end if

但是当检查Resource wasn't found.条件时，它会弹出if个错误。我尝试了theUser is in {"",value missing}，theUser is missing value等，但这些也无效。这有什么不对吗？

停止不应该在引号中。我假设您希望脚本在发送“退出”命令时停止执行。您可以通过添加取消按钮参数来完成此操作。

display dialog "Enter Your User Name:" default answer ""
set theUser to the text returned of the result

if theUser = "" then
    display dialog "User name is mandatory" buttons {"OK"} default button {"OK"} cancel button {"OK"} with title "Missing parameter" with icon stop
end if

检查Applescript中的缺失值
