如何解决“无法继续计数”的问题处理参数的 AppleScript 应用程序中出现问题？

我正在尝试在网上找到的一个简单的 AppleScript：

on run argv
 set rtn to ((count of argv) as text) & " parameters passed.
The parameters were:
"
 repeat with arg in argv
  set rtn to rtn & "      " & (arg as text) & "
"
 end repeat

 return rtn
end run

我将其保存为应用程序。每次我从 Finder 中双击它时，都会弹出以下错误消息：

无法继续计数

我似乎找不到任何方法来解决这个问题。

运行 Mac OS X Snow Leopard 10.6.4。

I'm trying out a simple AppleScript I found online:

on run argv
 set rtn to ((count of argv) as text) & " parameters passed.
The parameters were:
"
 repeat with arg in argv
  set rtn to rtn & "      " & (arg as text) & "
"
 end repeat

 return rtn
end run

I saved it as an Application. Everytime I double click it from the Finder, I get the following error popup:

Can't continue count

I can't seem to find any way to solve this.

当您双击它时，您没有传递任何参数，因此没有什么可计算的......所以它会出错。您可以使用 try 块来解决错误。试试这个...

on run argv
    try
        set rtn to ((count of argv) as text) & " parameters passed.
The parameters were:
"
        repeat with arg in argv
            set rtn to rtn & "      " & (arg as text) & "
"
        end repeat
    on error
        set rtn to "There are no arguments to count!"
        display dialog rtn buttons {"OK"} default button 1 with icon note
    end try
    return rtn
end run

When you double-click it you aren't passing any arguments so there's nothing to count... so it errors. You can get around errors with a try block. Try this...

on run argv
    try
        set rtn to ((count of argv) as text) & " parameters passed.
The parameters were:
"
        repeat with arg in argv
            set rtn to rtn & "      " & (arg as text) & "
"
        end repeat
    on error
        set rtn to "There are no arguments to count!"
        display dialog rtn buttons {"OK"} default button 1 with icon note
    end try
    return rtn
end run
