如何在苹果脚本中制作对话框以等待用户输入

Question

我正在尝试使用苹果脚本在 mac 中获得一个对话框。

    tell application "System Events"
    activate
    display dialog "Enter your name:  " default answer "" buttons {"OK"}   default button "OK" with title "Good Name"
    set the Name to text returned of the result

我面临的问题是，当我不输入名称时，弹出窗口自行关闭并抛出错误。但我希望它在用户输入之前一直存在

您需要添加一个 repeat 来处理错误：

set theMessage to ""
set theIcon to note

tell application "System Events"
    activate
    repeat
        display dialog theMessage & "Enter your name:  " default answer "" buttons {"Cancel", "OK"} default button "OK" cancel button "Cancel" with title "Good Name" with icon theIcon
        set the theName to text returned of the result
        try
            if theName = "" then error
            exit repeat
        on error
            set theMessage to "Invalid. "
            set theIcon to caution
        end try
    end repeat
    display dialog "Your name is " & theName & "." buttons {"OK"} default button "OK" with icon note
end tell

当输入为“”时，重复 on error 被触发，这会给出一条 invalid 消息并重复输入对话框——否则脚本继续（名称输出作为示例添加）。
