AppleScript 编程/示例程序/计算器
< AppleScript 编程 | 示例程序
这个简单的计算器使用了我们在数字和字符串部分、显示对话框部分以及基本命令部分中学到的知识。它还包括“if”和“else”语句以及“tell”块。尝试将它放到脚本编辑器中并运行它。

set opr to the button returned of the result
if opr is "Add" then --you clicked add
display dialog "Current equation: ?+?" & r & r & "What is the first number?" default answer "" --displays the current equation and
--asks for first number
set num1 to the text returned of the result

--equation and asks for next number
set num2 to the text returned of the result
display dialog "Equation: " & num1 & "+" & num2 & r & r & "Answer: " & num1 + num2 --displays the equation and calculates the answer
else --you clicked subtract

--asks for first number

set num2 to the text returned of the result

end if
此计算器脚本阻止除数字以外的所有内容输入。尝试将它放到脚本编辑器中并运行它。
