Syntax Applescript语法错误“；预期“；else”；，等，但找到了脚本的结尾。”；

我在applescript中遇到问题：

display dialog "Open Which Application" buttons {"Chrome", "AppleScript", "Textedit"} 
set the button_pressed to the button returned of the result
if the button_pressed is "Chrome" then
Open application "Google Chrome"-- action for 1st button goes here
if the button_pressed is "Applescript" then
Open application "Applescript Editor"-- action for 2nd button goes here
if the button_pressed is "Textedit" then
Open application "Textedit"-- action for 3rd button goes here
end

它一直在说语法错误：应该是“else”，等等，但找到了脚本的结尾

我该怎么办

您有三个

if

语句，但您只有

结束

其中一个

您可能需要的是

否则，如果

：

display dialog "Open Which Application" buttons {"Chrome", "AppleScript", "Textedit"}
set the button_pressed to the button returned of the result
if the button_pressed is "Chrome" then
    open application "Google Chrome" -- action for 1st button goes here
else if the button_pressed is "Applescript" then
    open application "AppleScript Editor" -- action for 2nd button goes here
else if the button_pressed is "Textedit" then
    open application "TextEdit" -- action for 3rd button goes here
end if

（另外，您实际上应该使用

end if

，而不仅仅是

end

，AppleScript编辑器将为您解决这一问题。）

或者，您可以

结束

每一项：

display dialog "Open Which Application" buttons {"Chrome", "AppleScript", "Textedit"}
set the button_pressed to the button returned of the result
if the button_pressed is "Chrome" then
    open application "Google Chrome" -- action for 1st button goes here
end if
if the button_pressed is "Applescript" then
    open application "AppleScript Editor" -- action for 2nd button goes here
end if
if the button_pressed is "Textedit" then
    open application "TextEdit" -- action for 3rd button goes here
end if

但是，这些情况显然是相互排斥的，因此没有理由不使用

else if

如果有帮助，请逐个键入这些行，然后查看AppleScript Editor是如何缩进它们的：

display dialog "Open Which Application" buttons {"Chrome", "AppleScript", "Textedit"} 
set the button_pressed to the button returned of the result
if the button_pressed is "Chrome" then
    Open application "Google Chrome"-- action for 1st button goes here
    if the button_pressed is "Applescript" then
        Open application "Applescript Editor"-- action for 2nd button goes here
        if the button_pressed is "Textedit" then
            Open application "Textedit"-- action for 3rd button goes here
        end

这会让问题变得显而易见。

试试：

display dialog "Open Which Application" buttons {"Chrome", "AppleScript", "Textedit"}
set the button_pressed to the button returned of the result
if the button_pressed is "Chrome" then tell application "Google Chrome" to activate -- action for 1st button goes here 
if the button_pressed is "Applescript" then tell application "AppleScript Editor" to activate -- action for 2nd button goes here 
if the button_pressed is "Textedit" then tell application "TextEdit" to activate -- action for 3rd button goes here end
