AppleScript - 當使用「從列表中選擇」時，變量命令不起作用

Question

我正在嘗試爲iTunes創建一個簡單的國際商店。

set country to (choose from list {"US", "CA", "UK"} with prompt "What country?") 

    if country = "US" then 
    tell application "iTunes" 
    activate 
    open location "itmss://itunes.apple.com/WebObjects/MZStore.woa/wa/switchToStoreFront?storeFrontId=143441" 
end tell 
end if 

當我點擊美國，它不會對iTunes做任何事情。我究竟做錯了什麼？

Answer 1

嘗試

if country as text = "US" then 

Answer 2

的問題是，choose from list命令返回從列表中選擇的項目列表。你可以做到以下幾點：

set country to (choose from list {"US", "CA", "UK"} with prompt "What country?") 

if country = {"US"} then 
    tell application "iTunes" 
     activate 
     open location "itmss://itunes.apple.com/WebObjects/MZStore.woa/wa/switchToStoreFront?storeFrontId=143441" 
    end tell 
end if 

或者，你可以說if item 1 of country = "US"。
