导出Library.scpt：执行错误：未定义变量ndx。 （-2753）它和＃34;本地＆＃34;行作为两个RECOGNIZED变量

Question

以下是相关代码：我相信错误正在＆＃34;重复＆＃34;阻止在最后。用于运行程序的命令行是：＆＃34; osascript Export \ Library.scpt / Users / bryandunphy / Development / iTunesLibraryConsolidator Testing.xml＆＃34;。

on run (clp)
    if clp's length is not 2 then error "Incorrect Parameters"
    local destination, libraryName, ndx
    set destination to clp's item 1
    set libraryName to clp's item 2
    menuClick({"iTunes", "File", "Library", "Export Library…"})
    tell application "System Events" to set the value of text field "Save As:" of window "iTunes" of process "iTunes" to libraryName
    tell pop up button 1 of group 1 of window "iTunes" of process "iTunes" of application "System Events" to click
    ndx = 1
    repeat
        if the title of menu item ndx is "" then
            select menu item (ndx - 1)
            exit repeat
        else
            ndx = ndx + 1
        end if
    end repeat
    my switchDir(destination, "iTunes", "iTunes", true, false)
    tell button "Save" of window "iTunes" to click
    return (destination & "/" & libraryName & ".xml")
end run

Answer 1

语言语义混乱。

sudo systemctl reload apache2语句声明变量但不定义（赋值）它（如在C中）。

声明

local

比较（当前未定义）变量ndx = 1 和1，

ndx

将值1赋值给变量set ndx to 1 （定义它）。

相若方式

ndx

行[{1}}后面的所有内容都必须位于set ndx to ndx + 1 告诉记录块
