限制对液滴的文件类型

Question

这问题并不局限于谁知道AppleScript的，如果你这样做可可等，你应该知道这个问题的答案的人：

  

我做的AppleScript中的液滴，其压缩JavaScript文件，所以很明显，我只想JavaScript文件被允许进入脚本。任何想法？

非常感谢。

Answer 1

property kJavascriptExtension : "js"
property pValidFileList : {}

on open of theFiles -- Executed when files are dropped on the script

    set fileCount to (get count of items in theFiles)

    repeat with thisFile from 1 to fileCount
        set theFile to item thisFile of theFiles
        set theFileAlias to theFile as alias

        tell application "Finder"
            set fileInfo to info for theFileAlias
            set fileName to name of fileInfo
        end tell

        set javascriptFileFound to isJavascriptFile(fileName) of me

        if (javascriptFileFound) then
            set end of pValidFileList to theFile
        end if
    end repeat

    display dialog "pValidFileList = " & pValidFileList
    -- do something with your files here
end open

on isJavascriptFile(theFilename) -- (theFilename as string) as boolean
    set AppleScript's text item delimiters to "."
    set fileNameList to every text item of theFilename
    set AppleScript's text item delimiters to ""

    try
        set theFileExtension to item 2 of fileNameList as string
    on error
        return false
    end try

    if theFileExtension is kJavascriptExtension then
        return true
    end if

    return false
end isJavascriptFile
