限制对液滴的文件类型 [英] Restrict file types on droplet

问题描述

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中的液滴的COM presses 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？

太感谢了。

解决方案

 属性kJavascriptExtension：JS
属性pValidFileList：{}开放theFiles的 - 打开时执行的文件被删除的脚本    集fileCount到（获得theFiles项目数）    与thisFile从1到fileCount重复
    设置theFile为theFiles项目thisFile
    设置theFileAlias​​为theFile的别名    告诉应用程序发现者
    设置的fileInfo为theFileAlias​​信息
    设置文件名对FileInfo名
    告诉结束    设置javascriptFileFound我的isJavascriptFile（文件名）    如果（javascriptFileFound），然后
    pValidFileList的设置结束theFile
    \t万一
    重复结束    显示对话框pValidFileList =＆放大器; pValidFileList
     - 做一些与你的文件在这里
开放式结尾在isJavascriptFile（theFilename） - （theFilename作为字符串）作为布尔
    设置的AppleScript的文本项分隔符。
    设置fileNameList为theFilename的每一个文本项
    设置的AppleScript的文本项分隔符为    尝试
    设置theFileExtension为字符串fileNameList第2项
    出错
    返回false
    年底试    如果theFileExtension是kJavascriptExtension然后
    返回true
    万一    返回false
结束isJavascriptFile
 

This question isn't limited to people who know AppleScript, if you do Cocoa, etc., you should know the answer to this:

I'm making a droplet in AppleScript that compresses JavaScript files, so obviously, I only want JavaScript files to be allowed into the scripts. Any ideas?

Thanks so much.

解决方案

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
