python-3.x - 如何在 AppleScript 中验证用户输入

问题描述

这是我第一次使用 AppleScript，如何添加验证以使用户无法在输入字段中提交空白信息？

firstname = """
display dialog "What is your name?" default answer "" ¬
buttons {"Submit"}
"""

标签： python-3.xapplescript

解决方案

以下是如何确保用户输入内容的一个示例：

set textReturned to ""
repeat while textReturned is equal to ""
    set textReturned to text returned of (display dialog ¬
        "What is your name?" buttons {"Submit"} ¬
        default button 1 default answer "")
end repeat

如果您想确保用户键入的内容不是空格字符（或粘贴在制表符中），请添加，例如：

if (do shell script "sed 's/[[:blank:]]//g'<<<" & ¬
    textReturned's quoted form) ¬
    is equal to "" then set textReturned to ""

所以它会是，例如：

set textReturned to ""
repeat while textReturned is equal to ""
    set textReturned to text returned of (display dialog ¬
        "What is your name?" buttons {"Submit"} ¬
        default button 1 default answer "")
    if (do shell script "sed 's/[[:blank:]]//g'<<<" & ¬
        textReturned's quoted form) ¬
        is equal to "" then set textReturned to ""
end repeat
