“on switchDir”例程用于定位作为“目录”传递的路径的每个元素，然后单击它以使目录路径潜入以到达所需的最终输出目录。
用鼠标激活所需的行。正常情况下，必须双击 才能选择它！
这是“on switchDir”的代码：
on switchDir(directory, appName, selectDefault, createIt)
local compname, bootvolume
set compname to get computer name of (system info)
set bootvolume to get boot volume of (system info)
if directory is equal to "~" then set directory to system attribute ("HOME")
if directory starts with "~/" then set directory to (system attribute ("HOME")) & text 2 through -1 of (get directory)
if not checkPathExists(directory) then
if createIt then
do shell script ("mkdir -p " & (POSIX path of directory))
else
return false
end if
end if
if directory begins with "/" then
set directory to bootvolume & (get directory)
end if
tell application "System Events" to tell (process "iTunes"'s front window)
delay 1
click pop up button 1 of group 1 -- selects the drop-down box above the directory listing
set max to the count of menu items of menu 1 of pop up button 1 of group 1 -- number of items in the drop-down menu
set ndx to 1
repeat while ndx ≤ max
if the title of group 1's pop up button 1's menu 1's menu item ndx as string is equal to compname then -- found the absolute top-level directory
click group 1's pop up button 1's menu 1's menu item ndx - so choose it and go to next part of navigation
exit repeat
else -- keep looking
set ndx to (get ndx) + 1
end if
end repeat
if ndx > max then error "Never found " & compname
set thePath to every item of my splitString(directory, "/") -- thePath equals every individual folder in the path's name in order
repeat with dir in thePath
set max to the (count of rows in outline 1 of scroll area 1 of splitter group 1 of group 1) -- max equals the number of rows in the "directory contents" list box
log max

log "found " & dir & " at row " & ndx as string
select row ndx of outline 1 of scroll area 1 of splitter group 1 of splitter group 1 of group 1 -- included to make sure the reference in the "click" statement is correct
click row ndx of outline 1 of scroll area 1 of splitter group 1 of splitter group 1 of group 1 -- supposed to "click" the desired folder name to choose it and dive deeper, BUT IT DOESN'T ACTUALLY DO THAT!
exit repeat -- apparently never executed because the loop keeps going past finding the desired directory's name and crashes at the first blank row!
else
set ndx to (get ndx) + 1
end if
if ndx > max then error "Never found " & dir
end repeat
end repeat
end tell
error "success"
return true
end switchDir
“on switchDir”中出现错误，仅包含其余代码，以便代码将在“脚本编辑器”下执行。 “点击行ndx ......”语句和“退出重复”语句显然从未执行，因为循环继续运行“已发现”的日志记录。 。 。 。并因此在列表框中的第一个空白行崩溃。找到的（带引号）可以用作搜索词来查找代码。
完整的，可运行的应用程序代码如下：

我重构了你的onSwitchDir函数，使其在我的机器上运行，并使其更具可读性。
我还添加了大量日志记录以帮助排除故障，随时删除。
on switchDir(directory, appName, selectDefault, createIt)
local compname, bootvolume
set sysInfo to (system info) -- cache value to reduce processing time
set compname to get computer name of sysInfo
log "compname: " & compname

if directory is equal to "~" then set directory to system attribute ("HOME")
if directory starts with "~/" then set directory to (system attribute ("HOME")) & text 2 through -1 of (get directory)
if not checkPathExists(directory) then
if createIt then
do shell script ("mkdir -p " & (POSIX path of directory))
else
return false
end if
end if
if directory begins with "/" then
set directory to bootvolume & (get directory)
end if
tell application "System Events" to tell (process "iTunes"'s front window)
-- ensure view is set to expanded view
try
click pop up button 1 of group 1
on error
key code 81 using {command down} -- expand view

if isFound is false then

set theOutline to outline 1 of scroll area 1 of splitter group 1 of splitter group 1 of group 1
set max to the (count of rows in theOutline) -- max equals the number of rows in the "directory contents" list box

set ndx to 2 -- row 1 is just the column titles
repeat while ndx ≤ max

set theElement to text field 1 of UI element 1 of theRow

if the value of theElement is equal to dir as string then
-- set focus so we can use keyboard commands on it
set value of attribute "AXFocused" of theOutline to true
-- select the item in the list
select theRow
-- set boolean so we can avoid re-running the repeat loop

set libraryName to value of text field "Save As:" of window "New iTunes Library" of process "iTunes"
delay 0.5
click process "iTunes"'s window "New iTunes Library"'s button "Save"
end tell
return libraryName
值得注意的变化：
exit repeat发布后继续退出menu 1 of pop up button 1 of group 1等项的引用，使脚本不那么密集且更容易阅读keystroke "o"命令，但是在重复循环之后放置它（由于某种原因它在循环中不起作用）group 1引用将导致错误。通过确保窗口展开，group 1结算，我不再收到错误。请注意，此脚本的结果是iTunes警告，它无法在请求的位置创建新库。我相信这是因为我只有你整个剧本的片段。我想你有代码的另一端，这将解决问题。如果是这样，您应该能够毫不费力地将这些更改合并到您的项目中。
